'''Basic Attack:''' Gravity Suppression\\
'''Skill:''' Edge of the Void\\
'''Ultimate:''' Synthetic Black Hole\\
'''Talent:''' Time Distortion\\
'''Technique:''' Gravitational Imprisonment\\\

An enigmatic man with a storied past. Hailing from a distant universe, Welt, then known as the Herrscher of Reason, led his organization, Anti-Entropy, against an omnicidal force known as the "Honkai" in a desperate battle for the survival of Earth. After a long, drawn-out war, the Honkai were expelled and Welt settled down working at an animation studio, but as luck would have it events conspired to separate him from his home universe. Following a long journey, Welt happened upon the Astral Express and joined its crew in hopes of finding his way back home. As the Herrscher of Reason, Welt possesses the ability to create perfect copies of any object that he understands, and by using his power to recreate the Star of Eden, Welt can manipulate gravity and black holes.\\

Wielding a cane which channels the power of the Star of Eden, a superweapon made from the core of a Herrscher, Welt manipulates gravity to rein in his enemies. His Skill, ''Edge of the Void'', slashes away at an enemy, as well as two other random targets, with a chance to reduce their Speed for two turns, while his Ultimate, ''Synthetic Black Hole'', has Welt create a black hole that sucks in all enemies and inflicts Imprison on them, which significantly delays their actions and reduces their Speed. His Talent, ''Time Distortion'', inflicts additional damage against Slowed enemies, while his Technique, ''Gravitational Imprisonment'', generates a high-gravity space which halves the Speed of enemies inside as well as Imprisons them for one turn.\\
\\
As Welt continues to draw on his past experiences, ''Synthetic Black Hole'' gains the ability to inflict a damage boost against enemies struck for two turns as well as regenerate additional Energy, and he can now inflict more damage against Weakness Broken enemies. When Welt decides to put his full might as the Herrscher of Reason on display, ''Synthetic Black Hole'' gains the ability to augment the next two instances of either ''Gravity Suppression'' or ''Edge of the Void'' with an additional attack, triggering ''Time Distortion'' can now generate some Energy, and ''Edge of the Void'' sees an increased chance to inflict its Speed reduction effect, as well as gains an extra random hit.\\
\\

* AreaOfEffect: ''Gravitational Imprisonment'' generates a force field that lasts fifteen seconds, within which enemies see their movement speeds halved, as well as Imprisons them for their first turn.

** March complains about Welt's uncanny ability to eavesdrop on conversations in some dialogue lines, alluding to Welt's SuperHearing power.

* CoolOldGuy: Welt is fairly kind and easygoing in spite of his stern appearance, and he has quite a few moments where he proves to be NotSoAboveItAll.
* DamageIncreasingDebuff: Welt's second-ascension Bonus Ability, ''Retribution'', gives ''Synthetic Black Hole'' a 100% base chance to increase incoming damage against enemies by 12% for two turns afterwards.

'''Basic Attack:''' Sawblade Tuning\\
'''Skill:''' Molten Detonation\\
'''Ultimate:''' Heavenly Flare\\
'''Talent:''' Victory Rush\\
'''Technique:''' Incomplete Combustion\\\

Along her journeys through the stars, Himeko specializes in pure damage-dealing by swinging around her circular saw disguised as a briefcase through her Basic Attack and Skill, ''Sawblade Tuning'' and ''Molten Detonation'', respectively, with the latter able to hit enemies adjacent to her target, while her Ultimate, ''Heavenly Flare'', has her command a satellite from high up in space to fire a laser beam on all her enemies, which also restores some of her Energy whenever enemies are defeated. Her Talent, ''Victory Rush'', allows Himeko to collect one stack of "Charge" whenever the party inflicts Weakness Break on an enemy, which are then consumed once three are collected to follow up her allies' attacks by summoning a drone that attacks the target with her saw, while her Technique, ''Incomplete Combustion'', creates a fiery field that, at the start of battle, reduces her enemies' Fire Resistance.\\
\\
As Himeko continues on her journey through the stars, all her attacks gain a chance to inflict Burn on her enemies for two turns, which gradually damage them at the start of their turn; ''Molten Detonation'' increases in damage potency against Burnt enemies; and she gains a boost to Critical Rate while her HP is very high. Once Himeko draws on the full extent of her experience, ''Victory Rush'' gains the ability to increase her Speed for two turns, all her attacks increase in power against enemies with less than half their HP, and ''Heavenly Flare'' gains two extra hits on random enemies.

* ChainsawGood: Her regular attack patterns involve swinging around a briefcase containing a circular saw.

* DamageIncreasingDebuff: ''Incomplete Combustion'' creates an area-of-effect that lasts fifteen seconds; if a battle is started within its radius, all enemies suffer a 10% boost to incoming Fire damage for two turns.

* GatheringSteam: ''Victory Rush'' allows Himeko to gather stacks of Charge whenever the party Weakness Breaks an enemy (with one stack prepared at the start of battle), which are then consumed once three have been gathered to allow Himeko to trigger a follow-up attack.[[note]]Damage is equivalent to 70–175% of her Attack stat[[/note]] In addition, her first Eidolon Resonance, ''Childhood'', allows the Talent to boost her Speed by 20% for two turns, while her fourth, ''Dedication'', grants her another stack of Charge whenever ''Molten Detonation'' triggers a Weakness Break.
* GuestStarPartyMember: Himeko becomes a temporary fourth party member (alongside the Trailblazer, March 7th, and Dan Heng) during an early exploration-related prologue quest in the Herta Space Station.
* HerdHittingAttack: ''Molten Detonation'' damages Himeko's target and surrounding enemies, with a higher damage to the former.[[note]]Depending on Trace levels, damage is equivalent to 100–250% of her Attack stat against her target, 40–100% to surrounding enemies[[/note]]
* KillSat: ''Heavenly Flare'' has Himeko calling down a massive OrbitalBombardment from a satellite floating in space and rain down hell on her enemies, with an opportunity to restore Energy for every enemy defeated.[[note]]Depending on Trace levels, damage is equal to 138–276% of her Attack stat[[/note]] Her sixth Eidolon Resonance, ''Trailblaze!'', adds two extra hits, each dealing damage worth 40% of the original damage to random enemies.

* ManaDrain: ''Heavenly Flare'' restores 5 Energy for Himeko for every enemy defeated.
* MsFanservice: Himeko is certainly quite the lovely sight, with her sensual outfit that accentuates her breasts and curves, as well as a refined appearance and mannerisms, including casually sipping coffee while ''Heavenly Flare'' rains down hell on her enemies.

-->(Ultimate activation) ''"Perhaps you still don't understand..."''
-->(Normal speed and ×2 speed) ''"Humanity never conceals its desires to control the heavens, and I am no exception."''

** Her fourth-ascension Bonus Ability, ''Magma'', increases the damage potency of ''Molten Detonation'' by 20% against Burnt enemies.

* UpgradeArtifact: A variant--her third Eidolon Resonance, ''Poised'', adds two levels to ''Molten Detonation'' and one to ''Sawblade Tuning'', while her fifth, ''Aspiration'', adds two each to ''Heavenly Flare'' and ''Victory Rush''.
* WeaponSpecialization: A variant--Himeko's associated Light Cone is "[[https://honkai-star-rail.fandom.com/wiki/Night_on_the_Milky_Way Night on the Milky Way]]" (5★), whose "Meteor Swarm" passive gives its wearer up to five stacks of a 9–15% Attack boost for every enemy in the field (to a maximum of 45–75%), as well as boosts their damage output by 30–50% for one turn after dealing a Weakness Break. Given that Himeko specializes in dealing with enemy mobs, this helps her swiftly dispose of them, as well as improves her viability against elite- or boss-grade enemies by increasing the power of all her attacks, manual or follow-up, whenever she breaks them.

* SmallRoleBigImpact: For the most part, Messenger is just a regular NPC you can interact with on the Astral Express, up until [[spoiler:you take March 7th's Companion Quest and discover that Messenger is responsible for suppressing March 7th's memories on orders from the Garden of Recollection]].

'''Basic Attack:''' Frigid Cold Arrow\\
'''Skill:''' The Power of Cuteness\\
'''Ultimate:''' Glacial Cascade\\
'''Talent:''' Girl Power\\
'''Technique:''' Freezing Beauty\\\

In the defense of her loved ones, March 7th specializes in erecting Shields and stopping enemies in their tracks, with her offensive potential typically limited to her Basic Attack, ''Frigid Cold Arrow''. Her Skill, ''The Power of Cuteness'', has March 7th install a Shield onto an ally that lasts up to three turns and draws enemy aggression onto them as long as their HP is not dangerously low, while her Ultimate, ''Glacial Cascade'', has her fire an icy arrow that rains down a series of icy stuffed toys that hit all enemies and randomly Freeze them, forcing them to lose a turn and take some damage. In addition, her Talent, ''Girl Power'', has her automatically counterattack whenever a Shielded character gets attacked, up to twice in between her turns, while her Technique, ''Freezing Beauty'', attacks enemies from a distance, hence automatically initiating battle, as well as Freezes a random enemy.\\
\\
As March 7th continues her journey to find herself, ''The Power of Cuteness'' gains the ability to remove a negative status effect from the targeted ally and the duration of the Shield it generates is extended to four, while ''Glacial Cascade'' sees an increased chance to Freeze enemies. Once March 7th nears the culmination of her journey, she can now regenerate Energy whenever ''Glacial Cascade'' freezes enemies, as well as gains the ability to automatically generate a Shield for the ally with the lowest remaining HP at the start of battle; ''Girl Power'' can now be activated thrice, in addition to a heightened damage output; and her generated Shields gain the ability to heal protected allies for every turn it is active.

* AntiDebuff: Her second-ascension Bonus Ability, ''Purify'', allows her to remove one debuff from the ally whom she uses ''The Power of Cuteness'' on.

* BarrierWarrior: ''The Power of Cuteness'' erects a Shield around an ally for three turns,[[note]]Depending on Trace levels, damage absorption is equivalent to (38–66.5%)+(190–973.75) of March 7th's Defense stat[[/note]] in addition to a DrawAggro effect if the ally has at least 30% HP. Her fourth-ascension Bonus Ability, ''Reinforce'', extends the Shield's duration to four turns, while her second Eidolon Resonance, ''Memory of It'', allows March 7th to automatically grant a less potent Shield to the ally with the lowest remaining HP percentage for the first three turns of the next battle,[[note]]Damage absorption is equivalent to 24%+320 of her Defense stat[[/note]] and her sixth, ''Just Like This, Always...'', heals the Shielded ally based on 4%+106 of their Max HP for every turn the Shield is intact.

* CounterAttack: ''Girl Power'' allows March 7th to immediately counter enemy attacks against a Shielded character up to twice in between her turns.[[note]]Depending on Trace levels, damage potency is equivalent to 50–125% of her Attack stat[[/note]] Her fourth Eidolon Resonance, ''Never Forfeit Again'', allows the Talent to be triggered thrice, in addition to a damage boost equivalent to 30% of her Defense stat.

* JackOfAllTrades: When fully upgraded, March 7th's kit has a little bit of everything. Alongside the powerful Shield, counterattack, and reasonably reliable area-of-effect Freeze in her base kit, her fourth Eidolon Resonance, ''Never Forfeit Again'', gives her counterattack a third charge and lets its damage additionally scale with her Defense, while her sixth, ''Just Like This, Always..'', adds a healing-over-time effect to her shield.
* KillItWithIce: ''Glacial Cascade'' has a base 50% chance to inflict Freeze on enemies for one turn, forcing them to lose that turn and take damage,[[note]]Damage equivalent to 30–75% of March 7th's Attack stat, in addition to 90–180% from the Ultimate[[/note]], while ''Freezing Beauty'' is guaranteed to Freeze a random enemy at the start of battle.[[note]]With subsequent damage equivalent to half of March 7th's Attack stat[[/note]] Her sixth-ascension Bonus Ability, ''Ice Spell'', increase the base rate to 65%.
* LineOfSightName: Sort of. Since the Astral Express crew found her on March 7, they simply picked that as her name.
* InsaneTrollLogic: March 7th tends to veer into this whenever she tries to piece something together on her own. An example appears in Luocha's Companion Quest, where she watches camera footage of Luocha entering an alley, then another clip that shows that Yinshu was the only person shown leaving the area for two hours afterwards. Her conclusion? Yinshu ''is'' Luocha, having somehow genderbent and de-aged himself into a little girl.

* MultipleChoicePast: While March 7th is investigating her past with Fu Xuan, she comes across several memory projections that throw out possible stories about her past, ranging from [[spoiler:being a refugee from either the disasters caused by the Propogation or Nanook, to being a fallen Aeon who has been cut off from its Path]].

* ThePollyanna: March 7th isn't the type of person to dwell in despair or even concern herself with the circumstances behind her own MysteriousPast. She simply lives her life for the moment, full of optimism, determination, and adding positive vibes to the Astral Express' journey even during the darkest moments.

-->(Ultimate activation) ''"Gotta try hard sometimes."''
-->(Normal speed) ''"Check out this awesome move!"''
-->(×2 speed) ''"Watch this awesome move!"''

* RegeneratingMana: March 7th's first Eidolon Resonance, ''Memory of You'', automatically restores 6 Energy for herself for every enemy Frozen with ''Glacial Cascade''.

-->'''March 7th''': [[spoiler:"No! That end won't come to pass while we're around!"]]

* SupportPartyMember: March 7th's kit packs an impressive amount of utility. ''The Power of Cuteness'' allows her to erect a Shield onto her allies (with her second-ascension Bonus Ability, ''Purify'', also adding a debuff removal effect), while ''Glacial Cascade'' has a hefty chance of inflicting Freeze on all enemies in addition to a respectable damage output. Should you unlock her Sixth Eidolon, her shield even gets a healing effect taped onto it.

* TookALevelInCynic: The events of Jarilo-VI has left her more distrustful of other people’s intentions as when Tingyun leads them to the Palace of Astrum, she’s openly questioning whether it’s a matter of time before Tingyun orders the Cloud Knights to arrest them. She also seems to dislike people of authority as she openly complains about Yukong’s chilly reception and has reservations about staying at a hotel after their last experience.

* UpgradeArtifact: A variant--her third Eidolon Resonance, ''Memory of Everything'', adds two levels to ''Glacial Cascade'' and one to ''Frigid Cold Arrow'', while her fifth, ''Never Forget Again'', adds two each to ''The Power of Cuteness'' and ''Girl Power''.
* WeaponSpecialization: A variant--March 7th's associated Light Cone is "[[https://honkai-star-rail.fandom.com/wiki/Day_One_of_My_New_Life Day One of My New Life]]," whose "At This Very Moment" increases its wearer's Defense by 16–24%, thus making her even tougher than she already is, as well as increases the party's Damage Resistance by 8–12%, hence expanding her defensive repertoire.

* PreAssKickingOneLiner:
-->(Ultimate activation) ''"The truth of life and death, revealed in an instant."''
-->(Normal speed and ×2 speed) ''"This sanctuary... is but a vision. Break!"''

* PreAssKickingOneLiner:
-->(Ultimate activation) ''"Rules are made to be broken."''

* PreAssKickingOneLiner:
-->(Ultimate activation) ''"Lance ablaze!"''
-->(Normal speed) ''"Flaming lance... forward!"''
-->(×2 speed) ''"Lance... forward!"''

* PreAsskickingOneLiner:
-->(Enemy Target Found) "We need a strategy."
-->(Battle Begins: Weakness Break - Destruction) "This is our chance."
-->(Battle Begins: Weakness Break - Preservation) "Time to go on the offensive."
-->(Battle Begins: Danger Alert) "Stay alert."

--> (Enemy Target Found) "That enemy certainly isn't friendly."
--> (Battle Begins: Weakness Break) "It's too late to repent."
--> (Battle Begins: Danger Alert) "Move carefully."

-->''"Humanity never conceals its desires to control the heavens, and I am no exception."''

* BoringButPractical: Their Preservation form is also rather simplistic, their Skill acting as a simple taunt and their Ultimate being an all-encompassing attack. However, their Attack stat barely changes from their Destruction form which allows them to deal respectable damage for what is otherwise a defensive Path,[[note]]With the damage of their Ultimate being calculated based on 50–125% of their Attack stat + 75–187.5% of their Defense, at high Trace levels it is comparable to that of their Destruction form's multi-target Ultimate against the primary target[[/note]]. Relatively speaking, however, they're less simple than their Destruction form due to their "Magma Will" mechanic and their intended role of tanking enemy attacks.

* UpgradeArtifact: Using "Shadows of Preservation" unique to them, their third Eidolon Resonance, ''Trail-Blazing Blueprint'', adds two levels each to ''Ever-Burning Amber'' and ''Treasure of the Architects'', and their fifth, ''Spirit-Warming Flame'', adds two to ''War-Flaming Lance'' and one to ''Ice-Breaking Light''.

'''Basic Attack:''' Cloudlancer Art: North Wind\\
'''Skill:''' Cloudlancer Art: Torrent\\
'''Ultimate:''' Ethereal Dream\\
'''Talent:''' Superiority of Reach\\
'''Technique:''' Splitting Spearhead\\\

With his trusty spear Cloud-Piercer on hand, Dan Heng fights with the swiftness of the wind and an ability to slow down his enemies. His Skill, ''Cloudlancer Art: Torrent'', is a four-hit strike that will inflict Slow on his target for two turns, which reduces his target's Speed, while his Ultimate, ''Ethereal Dream'', traps his enemy in a painting-like landscape, where he impales them with his spear, with a further increase in power if his target is Slowed. In addition, his Talent, ''Superiority of Reach'', allows his next attack to bypass a fraction of his target's Wind Resistance after receiving a buff from his allies, while his Technique, ''Splitting Spearhead'', increases his Attack stat for the first three turns of the next battle.\\

Once Dan Heng stops running away from his troubles, he gains the ability to avoid being targeted by enemies whenever his HP falls below half, he gains a chance to boost his Speed whenever he attacks, and ''Cloudlancer Art: North Wind'' can now enjoy a power boost against Slowed enemies. When Dan Heng fully resolves to take on his inner demons, he can now enjoy a boost to Critical Rate against enemies with over half their HP remaining, the cooldown time between successive activations of ''Superiority of Reach'' is reduced, his action turn is immediately put forward whenever he defeats an enemy with ''Ethereal Dream'', and the Slow status inflicted by ''Cloudlancer Art: Torrent'' further increases in penalty.\\
\\

* ArmorPiercingAttack: ''Superiority of Reach'' increases the Wind Resistance Penalty of Dan Heng's next attack[[note]]By 18–45% depending on Trace levels[[/note]] whenever he receives a StatusBuff from his allies, activated at least every two turns.
* CatapultNightmare: After leaving Jarilo-VI, Dan Heng has a nightmare involving Blade and wakes in this fashion, suddenly sitting up in a panic and breathing heavily. [[spoiler:Unfortunately for him, Kafka directs the Astral Express to the Xianzhou Luofu in pursuit of Stellaron activity, where none other than Blade is getting involved with Xianzhou authorities.]]
* ChainLethalityEnabler: His fourth Eidolon Resonance, '' Roaring Dragon and Soaring Sun'', allows him to take another turn if his Ultimate finishes an enemy off.

* CriticalHitClass: Players are incentivized to build up Dan Heng's Critical Rate to get a lot of mileage out of ''Cloudlancer Art: Torrent'', which is guaranteed to inflict Slow on his target whenever it scores a critical hit, as well as, indirectly, ''Ethereal Dream'', which enjoys greater damage against an afflicted enemy. In addition, his first Eidolon Resonance, ''The Higher You Fly, the Harder You Fall'', increases his Critical Rate by 12% whenever his target's HP is over half.
* DarkAndTroubledPast: While he refuses to outright discuss his past, he's got some particularly bad blood with the Xianzhou Luofu to the point where he's essentially "kill on sight" if he ever dares step foot in it again. It's also mentioned in one of his stories that he's changed his appearance numerous times while running from whatever it is he's running from. That said, he fears Blade even more than the Alliance, [[spoiler:which causes alarm bells to go off when he finds out that Blade is on the Xianzhou Luofu and convinces him to board the ship to warn his friends]].

* ExtraTurn: In a variant, his fourth Eidolon Resonance, ''Roaring Dragon and Soaring Sun'', [[CooldownManipulation automatically pushes forward his next action]] whenever he defeats an enemy with ''Ethereal Dream''.

* GlassCannon: Dan Heng can deal very high damage and is very fast, as expected of his Hunt archetype, but he has low HP and Defense, and can't take a hit very well, though this can be ameliorated through his second-ascension Bonus Ability, ''Hidden Dragon'', which reduces the chance of enemies targeting him whenever his HP falls below half.

* IChooseToStay: [[spoiler:After completing his Companion Mission, Dan Heng is offered a chance to resettle in his homeland by Jing Yuan, with the former's banishment having been revoked. Inverted however, as Dan Heng insists that the Astral Express still needs him and is staying with them through thick and thin]]

* MartialPacifist: If his combat voice lines are any indication, Dan Heng doesn't particularly enjoy fighting and typically tries to avoid it whenever possible. In Belobog, [[spoiler:he was [[ProperlyParanoid justifiably opposed]] to telling Cocolia all the details about the Astral Express's purpose and the Stellaron, fearing it would lead to conflict.]]
-->''"I have no interest in conflict."''
-->''"Fighting is meaningless."''
* MythologyGag: Dan Heng is the ''Honkai: Star Rail'' counterpart of Xiao, as well as to some extent Kaedehara Kazuha, from an earlier [=miHoYo=] RPG, ''VideoGame/GenshinImpact''--in general, all three are handsome, youthful-looking men with wind-aligned powers and are haunted by {{Dark and Troubled Past}}s; in particular, Dan Heng shares Xiao's mastery of the spear and origins in a place with a Chinese cultural aesthetic, as well as Kazuha's maple-leaf aesthetic and fugitive status.

-->(Ultimate activation) ''"The truth of life and death, revealed in an instant."''
-->''"This sanctuary... is but a vision. Break!"''
* ReduceAggro: His second-ascension Bonus Ability, ''Hidden Dragon'', reduces the chances of enemies targeting him whenever his HP falls below half.
* SimpleYetAwesome: Of the three starter characters, Dan Heng's kit is the most straightforward, lacking the Trailblazer's adaptability or March 7th's sheer utility. The choice between using his Basic Attack, Skill, and Ultimate can be boiled down to how hard he wants to hit one enemy at a time. Relative to his fellow Hunt Pathstriders, Dan Heng also lacks additional gimmicks (e.g., Seele's ExtraTurn, Yanqing's FullHealthBonus, or Sushang's damage bonus against Weakness Broken enemies), the closest being that his Ultimate deals bonus damage against [[SituationalSword Slowed enemies]]. Despite this, Dan Heng is one of the strongest DPS units in the early game, and among the launch characters his single-turn damage is second only to Seele.[[labelnote:note]]Seele and Dan Heng are calculated on single-turn damage, without Eidolon Resonances, with their respective optimal Relics, equivalent critical hit stats, and Superimposition 5 Cruising in the Stellar Sea, where Dan Heng deals about 1% less than Seele. However, because of Seele's ExtraTurn ability, the difference is more pronounced in practice. See [[https://www.prydwen.gg/star-rail/dps-rankings/ here]] for more details.[[/labelnote]]
* SinsOfOurFathers: [[spoiler:Even though Dan Feng's sins were supposed to be extinguished after his reincarnation into Dan Heng, Dan Heng was still punished for the acts of his previous incarnation by being banished from the ''Luofu'']].
* SituationalSword: ''Ethereal Dream'' increases in damage potency against Slowed enemies.[[note]]Depending on Trace levels, its damage is equivalent to 240–480% of Dan Heng's Attack stat by default, 312–624% against a Slowed enemy[[/note]] In addition, Dan Heng's sixth-ascension Bonus Ability, ''High Gale'', adds a 40% damage boost for ''Cloudlancer Art: North Wind'' against Slowed enemies.

* StatusBuff: ''Splitting Spearhead'' boots Dan Heng's Attack by 40% for the first three turns of the next battle, while his fourth-ascension Bonus Ability, ''Faster Than Light'', grants him a 50% chance to enjoy a 20% Speed boost for two turns whenever he attacks.
* StatusInflictionAttack: ''Cloudlancer Art: Torrent'' has a guaranteed chance to inflict Slow on Dan Heng's target for two turns whenever it lands a critical hit (specifically, by imposing a 12% penalty on their Speed). His sixth Eidolon Resonance, ''The Troubled Soul Lies in Wait'', increases the penalty to 20%.
* TheStoic: He never talks about his past and is quite serious, putting him in contrast with March. The only time that he has displayed more expressive emotion is after waking up in a panic from a nightmare in the "Nightmare" trailer. [[spoiler:In the game proper, his mask of stoicism also has a rock taken to it when he realizes Blade is on the Luofu, and the Trailblazer, March 7th, and Welt have marched right on board, blissfully unaware of just who or what they're facing.]]

* UpgradeArtifact: A variant--his third Eidolon Resonance, ''Seen and Unseen'', adds two levels to ''Cloudlancer Art: Torrent'' and one to ''Cloudlancer Art: North Wind'', while his fifth, ''A Drop of Rain Feeds a Torrent'', adds two each to ''Ethereal Dream'' and ''Superiority of Reach''.
* WeaponSpecialization: A variant--Dan Heng's associated Light Cone is "[[https://honkai-star-rail.fandom.com/wiki/Only_Silence_Remains Only Silence Remains]]" (4★), whose "Record" passive increases his Attack stat by 16–32%, as well as Critical Rate by 12–24% if there are less than two enemies in the field. With the way his kit works, the latter boost increases his chances of inflicting Slow with his Skill (thus increasing his Ultimate's chance to deal more damage), especially when there are a few enemies left or when facing off against bosses.

Long ago, the Aeon of the Trailblaze, Akivili, yearned to travel the universe. To accomplish this, they created the Star Rail, and established tracks to link together every world in the galaxy. During their travels, they amassed a group of like-minded individuals who would join them on their adventures. Though the original group and Akivili are long gone, their legacy continues. At some point in her life, a scientist named Himeko discovered the remains of the Star Rail, and repaired it herself. Now she and her companions roam the universe lending a hand to those who need it.

* AllPowerfulBystander: Himeko and Welt, the two elder members of the Nameless, possess far more experience than their younger peers and incredible powers that would easily match many of the things the Trailblazer faces. But Himeko feels that HelpingWouldBeKillStealing and that the younger members deserve to get to experience the adventure on their own. That said, Himeko and Welt aren't averse to providing "off-site" help when it's warranted, [[spoiler:such as when Himeko uses her KillSat attack to disable one arm of the [[HumongousMecha Engine of Creation]], saving the heroes from a messy fate.]]

* TheSleepless: Downplayed. The Trailblazers can go for days without sleep thanks to Akvili's blessing, but once they do go to sleep, they need to catch up on all those days they missed. So it's frequent for them to sleep in extra late after a lot of exertion.

* DubNameChange: In the Chinese dub, the female and male Trailblazers' {{Canon Name}}s are respectively 星 (''Xīng'', "star") and 穹 (''Qióng'', "sky")[[note]]A rarely used character which is not interchangable in everyday Mandarin with 空 (''kōng'', also "sky"), the Chinese name for Aether, the male Traveler of ''VideoGame/GenshinImpact''[[/note]], both of which form part of the Chinese name for ''Honkai: Star Rail'' (崩坏：星穹铁道, ''Bēnghuài: Xīngqióng Tiědào''). In Japanese, the same characters can be read as "Hoshi" (ほし) and "Sora" (そら) via ''kun'yomi'' (native Japanese reading), and in Korean as "Seong" (성) and "Gung" (궁), whereas the English dub uses their respective German and Latin counterparts.

* MysteriousPast: They definitely existed prior to the start of the story, as Kafka specifically knows them and they recognize her on sight. But their [[AmnesiacHero memory loss]] is an intentional part of the plan to get them traveling alongside the Astral Express in search of the truth.
** Blade confirms in Kafka's Companion Quest that [[spoiler:the Trailblazer had been traveling with Kafka long before the events of the game and was apparently a close companion of hers]].

* RedOniBlueOni: Downplayed since both gender of the Trailblazer are generally TheStoic, but there is a slight difference in personality between Stelle and Caelus, particularly when delivering their PreAssKickingOneLiner during battle. The former is calm and elegant, while the latter is aggressive and brutal.
* ReligiousAndMythologicalThemeNaming: Caelus is named after the [[https://en.wikipedia.org/wiki/Caelus Roman primordial sky god]].

'''Basic Attack:''' Farewell Hit\\
'''Skill:''' RIP Home Run\\
'''Ultimate:''' Stardust Ace\\
'''Talent:''' Perfect Pickoff\\
'''Technique:''' Immortal Third Strike

Upon catching the attention of Nanook, the Aeon of Destruction, the Trailblazer is endowed with the Path of Destruction, dealing Physical damage with their bat, either to a single enemy with their Basic Attack, ''Farewell Hit'', or to multiple foes with their Skill, ''RIP Home Run''. Their Ultimate, ''Stardust Ace'', supercharges their bat, transforming their next use of ''Farewell Hit'' or ''RIP Home Run'' into a ''Blowout'', dealing massive damage, while their Talent, ''Perfect Pickoff'', grants them a stacking Attack boost whenever they break an enemy's Weakness. Out of combat, their ''Immortal Third Strike'' technique heals the entire party for a percentage of their max HP.\\
\\
As the Trailblazer continues to walk the path of Nanook and dedicate themselves to eradicate the threat of the Antimatter Legion, they unlock Traces and Eidolons to enhance their abilities: they gain Energy at the start of battle, receive a Defense boost from ''Perfect Pickoff'' stacks, and deal increased damage with ''RIP Home Run'', as well as restore Energy whenever they defeat enemies with ''Blowout''-enhanced attacks, heal some of their HP based on their Attack stat when they damage enemies weak to Physical, gain bonus Critical Rate when attacking Weakness Broken enemies, and also receive ''Perfect Pickoff'' stacks from defeating enemies.

* CrutchCharacter: Somewhat downplayed, as the Trailblazer of Destruction can remain viable in more difficult content, such as the Hall of Memory or the later levels in the Simulated Universe, but once the player has access to other damage dealers, the Trailblazer ends up lagging behind in terms of damage output, as [[JackofAllStats they don't truly specialize]] in any one area.
* GatheringSteam: ''Perfect Pickoff'' gives the Trailblazer a stack of an Attack buff (of which they can hold up to two at a time) whenever they inflict Weakness Break on an enemy. Their fourth-ascension Bonus Ability, ''Perseverance'', allows each stack to also improve their Defense, and their sixth Eidolon Resonance, ''A Trailblazing Will'', also allows them to gain stacks via landing kills.
* HealingFactor: ''Immortal Third Strike'' is an on-demand field heal that restores the party's HP based on 15% of each character's Max HP, while the Trailblazer's second Eidolon Resonance, ''An Unwilling Host'', restores their HP based on 5% of their Attack stat whenever they hit enemies weak to Physical attacks.
* HerdHittingAttack: ''RIP Home Run'' hits up to three enemies at once, one on either side of the Trailblazer's principal target.[[note]]Damage is equivalent to 62.5–156.25% of the Trailblazer's Attack stat[[/note]] In its Blowout form, the principal target will take more damage.[[note]]180–325% to the target, 108–189% to surrounding enemies[[/note]] The Trailblazer's sixth-ascension Bonus Ability, ''Fighting Will'', adds a fixed 25% damage boost to both forms.

* MechanicallyUnusualFighter: Their Ultimate of this path, ''Stardust Ace'', is the only one with two modes of operation (Single Target or Blast) and whose animation plays immediately upon activation before selecting the target.

* PreAssKickingOneLiner:
-->''"Rules are made to be broken."''
* RegeneratingMana: Their second-ascension Bonus Ability, ''Ready for Battle'', restores 15 Energy at the start of battle, while their first Eidolon Resonance, ''A Falling Star'', restores 10 Energy whenever either ''Blowout: Farewell Hit'' or ''Blowout: RIP Home Run'' defeat at least one enemy.
* StanceSystem: ''Stardust Ace'' allows the Trailblazer to unleash upgraded "Blowout" forms of either ''Farewell Hit'' or ''RIP Home Run'', with heightened damage against the principal target of the latter, and even more so with the former.[[note]]For the former, damage is equivalent to 300–525% of the Trailblazer's Attack stat compared to 50–130% in its base form; for the latter, 180–325% to the target and 108–189% to surrounding enemies, compared to a uniform 62.5–156.25% in its base form[[/note]]
* StatusBuff: ''Perfect Pickoff'' boosts the Trailblazer's Attack[[note]]by 10–25%[[/note]] each time they land a Weakness Break, which can be stacked up to two per battle.[[note]]Equivalent to 20–50%[[/note]] Their fourth-ascension Trace, ''Perseverance'', also allows each stack to grant a 10% Defense boost (to a maximum of 20%), while their sixth Eidolon Resonance, ''A Trailblazing Will'', automatically triggers the Talent whenever they defeat at least one enemy.
* UpgradeArtifact: A variant--their third Eidolon Resonance, ''A Leading Whisper'', adds two levels each for ''RIP Home Run'' and ''Perfect Pickoff'', and their fifth, ''A Surviving Hope'', adds two for ''Stardust Ace'' and one for ''Farewell Hit''.

'''Basic Attack:''' Ice-Breaking Light\\
'''Skill:''' Ever-Burning Amber\\
'''Ultimate:''' War-Flaming Lance\\
'''Talent:''' Treasure of the Architects\\
'''Technique:''' Call of the Guardian

When their desire to protect their loved ones brings the favor of Qlipoth, the Trailblazer gains the ability to draw enemies away from their allies and scorch them with their fiery lance, in particular by gathering stacks of "Magma Will" through their Basic Attack, ''Ice-Breaking Light'', which are then consumed once four are gathered to allow the Basic Attack to hit enemies around their target. Their Skill, ''Ever-Burning Amber'', has the Trailblazer goad enemies into targeting them, all the while taking up a defensive stance that increases their Damage Reduction as well as adding a stack of Magma Will, while their Ultimate, ''War-Flaming Lance'', scorches all enemies with damage based on a sum of fractions of their Attack and Defense stats, as well as automatically upgrades the next ''Ice-Breaking Light'' used, with a negated Magma Will consumption. In addition, their Talent, ''Treasure of the Architects'', allows them to gather up to eight stacks of Magma Will whenever they take a hit, as well as automatically boost the next ''Ice-Breaking Light'' and bestow Shields upon the party whenever they attack enemies, and their Technique, ''Call of the Guardian'', erects a Shield around the Trailblazer that lasts for their first turn.\\
\\
As the Trailblazer continues to walk the path of Qlipoth, ''Ever-Burning Amber'' gains the ability to boost their allies' Defense, the enhanced form of ''Ice-Breaking Light'' can now simultaneously heal the Trailblazer, and they can enjoy increased Attack and restore some Energy for every turn their Shield is intact. Once the Trailblazer's desire to protect their loved ones burns brighter than ever, both the damage of ''Ice-Breaking Light'' and the damage absorption of Shields they erect increase in potency based on a fraction of their Defense stat, they are now automatically granted four stacks of Magma Will at the start of battle, and both the enhanced form of ''Ice-Breaking Light'' and ''War-Flaming Lance'' gain the abilty to increase their Defense.

* BarrierWarrior: ''Treasure of the Architects'' erects Shields onto the party whenever the Trailblazer hits enemies for two turns.[[note]]Damage absorption is equivalent to (4–7%)+(20–102.5) of the Trailblazer's Defense stat[[/note]] In addition, ''Call of the Guardian'' allows the Trailblazer to erect a Shield that lasts through the first turn;[[note]]Damage absorption is equivalent to 30%+384 of the Trailblazer's Defense stat[[/note]] their sixth-ascension Bonus Ability, ''Action Beats Overthinking'', increases their Attack stat by 15% and restores 5 Energy for every turn the Shield is intact; and their second Eidolon Resonance, ''Time-Defying Tenacity'', further increases the Shield's resiliency.[[note]]Absorption is increased based on 2%+27 of the Trailblazer's Defense stat[[/note]]
* BoringButPractical: Their Preservation form is also rather simplistic, their Skill acting as a simple taunt and their Ultimate being an all-encompassing attack. However, their Attack stat barely changes from their Destruction form which allows them to deal respectable damage for what is otherwise a defensive Path,[[note]]With the damage of ''War-Flaming Lance'' being calculated based on a sum of 50–125% of the Trailblazer's Attack stat and 75–187.5% of their Defense, at high Trace levels it is comparable to that of ''Blowout: RIP Home Run'' against the primary target[[/note]] especially with their Talent that turns their Basic Attack into splash damage for every four times they are hit.
* DamageReduction: Their second-ascension Bonus Ability, ''The Strong Defend the Weak'', allows ''Ever-Burning Amber'' to reduce the party's incoming damage by 15% for one turn.
* DrawAggro: ''Ever-Burning Amber'' goads enemies into targeting the Trailblazer for one turn, who in turn gathers one stack of Magma Will and takes up a defensive stance that increases their Damage Reduction.[[note]]By 40–55% depending on Trace Levels[[/note]]

* GatheringSteam: The Trailblazer of Preservation can collect up to eight stacks of Magma Will whenever they use ''Ice-Breaking Light'' or ''Ever-Burning Amber'' or are damaged. Once at least four are collected, the former will be upgraded to increase damage as well as damage range.[[note]]Damage is equivalent to 90–168.75% of the Trailblazer's Attack stat against primary target (compared to 50–130% in its base form), 36–67.5% to surrounding enemies[[/note]] ''War-Flaming Lance'' automatically upgrades the next ''Ice-Breaking Light'' and negates its Magma Will cost. On a related note, the Trailblazer's first Eidolon Resonance, ''Earth-Shaking Resonance'', increases the damage potency of ''Ice-Breaking Light'' based on 25% of their Defense stat, twice so on its upgraded form, while their fourth, ''Nation-Building Oath'', automatically grants four stacks of Magma Will at the start of battle.
* HealingFactor: Their fourth-ascension Bonus Ability, ''Unwavering Gallantry'', restores their HP by 5% of its maximum value whenever they use the upgraded form of ''Ice-Breaking Light''.
* KnightInShiningArmor: The Trailblazer's Preservation form was unlocked out of a desire to protect Belobog from [[spoiler:a Stellaron-addled Cocolia]]. Fittingly, their weapon is a jousting lance.
* LegendaryWeapon: The "Everwinter City Museum Ledger of Curiosities" limited-time event reveals that the lance they use in their Preservation form once belonged to Alisa Rand, the first Supreme Guardian of Belobog.

* MightyGlacier: Unlike other [[StoneWall Preservation]] characters. On top of the shield they can regenerate with every action, ''Ever-Burning Amber'' reduces all damage by almost half even at at base level and can boost their defence to an insane degree, allowing them to take a lot of punishment from enemies. They can also put out impressive damage with their enhanced basic attacks and Ultimate ability. Their speed stat also becomes lower in this form; this gives them less chances of attacking and more for defending[[note]]Though optimally, they'll like to be faster than most enemies so that they can use their defensive skills first[[/note]].

* PlayingWithFire: The Trailblazer's lance is infused with flaming hot magma. Burying it in the ground with 4 stacks of ''Magma Will'' causes bursts of fire to erupt from the ground. Meanwhile, their Ultimate ability, ''War-Flaming Lance'', has them rush past their foes, causing a trail of explosions before making the battlefield erupt with an enormous plume of fire.
* PreAssKickingOneLiner:
-->(Ultimate activation) ''"Lance ablaze!"''
-->(Normal speed) ''"Flaming lance... forward!"''
-->(×2 speed) ''"Lance... forward!"''

* StatusBuff: Their sixth Eidolon Resonance, ''City-Forging Bulwarks'', increases their Defense stat by 10% whenever they trigger the enhanced form of ''Ice-Breaking Light'' or ''War-Flaming Lance'', to a maximum of three stacks (equivalent to 30%).
* UpgradeArtifact: A variant--their third Eidolon Resonance, ''Trail-Blazing Blueprint'', adds two levels each to ''Ever-Burning Amber'' and ''Treasure of the Architects'', and their fifth, ''Spirit-Warming Flame'', adds two to ''War-Flaming Lance'' and one to ''Ice-Breaking Light''.
