* PapaWolf: [[spoiler:The motivation for his RoaringRampageofRevenge against the IPC, as they killed his family.]]

* TooManyBelts: Besdies the typical JRPG belts dotting her outfit, Black Swan also has a leather belt prominently wrapped over the top of her ''veil'' of all things.

* AlternateSelf: Of Raiden Mei from [=Gun Girl Z=] and ''VideoGame/HonkaiImpact3rd'', sharing her Chinese and Japanese voice actresses. [[spoiler: Izumo's downfall heavily mirrors that of HI3's Previous Era (with some elements from the present-day story), and she admits to finding the veiled story Welt tells of Kevin Kaslana and Project Stigma familiar.]]

* AxCrazy: When he realizes he's speaking with Black Swan and not Acheron over the phone, his first assumption is that she's there to be Acheron's bodyguard, so he immediately offers to put a bullet in Black Swan's head and asks her to clean her forehead in preparation for it. [[spoiler: Turns out he has a pretty good reason to be off his rocker too.]]

* GoshDangItToHeck: He's actually rather foul-mouthed, but a malfunction in his [[TranslatorMicrobes Synesthesia Beacon]] causes his dirty language to come off as sounding cutesy or corny instead.

* {{Revenge}}: According to his introduction post, he has a score to settle with the [=IPC=].

** It is speculated the Stellarons are artifacts of Nanook spread across the universe in the Aeon's effort to systematically destroy everything. However, whether or not this is the case remains to be seen. At one point Nanook blesses the Trailblazer to fight against a Doomsday Beast of Nanook's own Antimatter Legion. Yet, not long after that Qlipoth the Preservation also does the same; the fact multiple Aeons could bless a single person with a Stellaron inside them strongly suggests they are not particularly affiliated with a single Aeon.
** It is shown the powers of Stellarons can freely influence and interact with those of Aeons. Not only can Stellarons in general affect Imaginary Energy which Akivili's Astral Express relies on for space travel, the Stellaron inside the Trailblazer can harness both Nanook and Qlipoth's blessings for the host's use. And in Luofu, another Stellaron displays it can accelerate the side effects of Yaoshi's blessing of immortality in the citizens of Xianzhou, making them turn into Mara-Stricken monsters at a much more rapid pace. All of these suggest there is a certain degree of connection between the nature and powers of Aeons and Stellarons.
* BeCarefulWhatYouWishFor: Jarilo-VI Stellaron first responded to a wish to stop a planet-destroying threat by essentially rendering said planet inhabitable as a frozen landscape. The Luofu Stellaron also responds to the local population of immortal-hating people by accelerating the degeneration and monster transformation of the people. If all Stellarons are sentient, this might in fact be their modus operandi.

* JackassGenie: The Jarilo-VI Stellaron was first contacted by the Supreme Guardian Alisa Rand, who wished to eliminate the invading Antimatter Legion. It did so... by summoning the Eternal Freeze, which froze most of the world in the process. It wiped out or stopped cold both the invading Legion and just about every person on the planet outside of Belobog.

** As seen so far with Jarilo-VI and the Xianzhou Luofu, the Stellarons grants people their wishes but with a negative consequence, this method is very similar to how Sa is able to destroy bubble universes by granting them their wishes.

* RealityWarper: Stellarons harness Imaginary Energy, i.e. the very energy which sustains reality and its phenomenons. One Stellaron freezes an entire planet along with a horde of the Antimatter Legion -- an entire army blessed by Nanook, who is also this trope -- and another Stellaron can affect the immortality blessing of Yaoshi on mortals, implying Stellarons might be this trope on a scale comparable to [[PhysicalGod Aeons themselves]].

!!Acheron

An interstellar-wide nation that perished due to a Swarm invasion. It was once known for their advancements in warfare technology, chiefly the "Iron Cavalry Regiment" that relentlessly fought against the Swarm, and their leader, Empress Titania; however, the sheer amount of debris from the war blotted out their world's sun, and their civilization eventually faded away. It's the subject of the Planar Ornament "Firmament Frontline: Glamoth".

* AmbiguousSituation: While the "river of debris" did exist as the aftermath of the war, the Intelligensia Guild has different interpretations as to how the war ended: one side believes that the Swarm completely destroyed them, while another side believes that the nation "completely overshot its enemy".
* ArchEnemy: TheSwarm, as much of the known history about Glamoth is about the war between the two.

* KnightInShiningArmor: According to the dream of the "Welkin Empire", Glamoth's Iron Cavalry was described as "silver-white iron knights", and that "their arrival was like a gift from the gods, bringing the light of day back to the human world".

* SuperSoldier: the Iron Cavalry Regiment is this in a nutshell, warriors with PoweredArmor and highly destructive capabilities. The way they're described, they were implied to be [[TykeBomb raised from a young age to shape them all as soldiers]].

** Her Basic Attack has a additional 50--68% chances of inflicting more Arcana for each damage-over-time debuff (i.e., Wind Shear, Burn, Bleed, Shock) active on her target. Her second-ascension Bonus Ability, ''Viscera's Disquiet'', gives her Skill a 65% base chance to also inflict Arcana in the same manner.

Dr. Ratio castigates all who fail to meet his standards with his Talent, ''Cogito, Ergo Sum'', which grants a chance to hurl a high-velocity piece of chalk as a follow-up attack when striking with his single-target Skill, ''Intellectual Midwifery'', that increases for each debuff on the enemy; or his Ultimate, ''Syllogistic Paradox'', where he summons a giant pillar to collapse onto his target and inflicts them with Wiseman's Folly, which guarantees him to attack twice with his Talent whenever the marked foe is struck by his allies. In addition, his Technique, ''Mold of Idolatry'', generates a plaster statue of himself that draws enemy aggression as well as reduces their Speed for the first two turns of battle.[[note]]When fully upgraded, his damage output increases against foes with at least three debuffs, with a further boost proportional to the number of further debuffs; his Skill gains up to six stacks of a Critical Rate and Damage boost proportional to the number of debuffs on his target (with a further upgrade increasing the cap to ten and allows him to immediately gather four at the start of battle), as well as sees a heightened chance to reduce his target's Effect Resistance for two turns; his Talent's follow-up attack is augmented with additional hits depending on the number of his target's debuffs, as well as restores some Energy; and Wiseman's Folly can now trigger his Talent thrice.[[/note]]

* BreakingOldTrends: Dr. Ratio is the first unit of the Hunt Path whose kit has no innate means of increasing his speed or advancing his actions, instead representing the path's focus on rapidity through a deluge of hard-hitting follow-up attacks.

* TheComicallySerious: He's prone to some odd behaviors like wearing a plaster head cover, making flamboyant poses (including in his statues) or speaking in fancy terminology. And he does all that with complete seriousness.

** His second Ascension bonus ability, ''Summation'' has him gain an increase to his Critical Rate and Damage by 2.5% and 5%, respectively, [[StatusEffectPoweredAbility for every debuff the enemy has]] when he uses his skill on them ([[GatheringSteam up to six]], for a max of 15% and 30% respectively), lasting for the entire battle. His first Eidolon Resonance ''Pride Comes Before a Fall'' increases the maximum stack count to ten (for a maximum 25% and 50%), and immediately grants four stacks at the start of combat.
* DeathFromAbove: His Ultimate has him summon a giant column, which then crumbles and topples onto a single enemy for massive damage.[[note]]Its damage is 144%–259.2% of his ATK[[/note]]
* DiscOneNuke: For players who started playing between the second phase of Version 1.6 and the end of Version 2.1, Dr. Ratio can be immediately obtained from the mail as soon as the prologue Trailblaze mission, "A Moment of Peace", is completed, allowing Dr. Ratio to become part of their initial starting roster. Being a 5★ Imaginary Hunt unit, he can become a strong source of Imaginary damage early on for players who do not have Welt, Luocha, or Imbibitor Lunae (all three of them are also 5★, with the latter two being on a time-limited banner), long before obtaining the 4★ Yukong, who is given for free significantly later in the story.

* DudeWheresMyRespect: Even if he is critical of the Genius Society and his accomplishments are on par with theirs, his character story implies that he always wanted to join the Genius Society but was unable to do so as Nous never gave their gaze upon him. Recognizing this, he set out to spread knowledge and possibly make everyone on par with the people who shared Nous' gaze and privileges instead.
--> '''Dr. Ratio:''' If this day I have not gained the recognition of Nous - then it stands to reason that I never will at any point in the future.

* ExactWords: [[spoiler:Sunday asks Dr. Ratio if he would be willing to betray Aventurine, which Dr. Ratio denies. Sunday bribes him with the promise of Stellaron research anyways and Dr. Ratio reveals Aventurine's entire plan to him. However, the scholar never actually said he would betray Aventurine, and the plan he leaked was really a decoy to throw Sunday off]].

* GlassCannon: He's capable of decent damage but has low defenses like other Hunt Pathstriders.

* ShapingYourAttacks: His Skill takes the form of summoning a tetrahedron made of light to strike at his target (representing a math problem).[[note]]Depending on Trace levels, the damage of his Skill is equivalent to 75–165% of his Attack stat[[/note]]

** His combat kit performs at its best against enemies suffering from debuffs and damage-over-time effects, which is primarily the domain of Nihility characters. Quite fitting that an educator whose purpose is to fill vacant minds with knowledge would be at his prime when working off other characters whose Path represents emptiness.

* StatusEffectPoweredAbility: This is his main gimmick.
** His Talent has him [[ChuckingChalk toss a chalk at enemies]] as a [[OutOfTurnInteraction follow-up attack]] [[note]]Depending on Trace levels, its damage is equivalent to 135–297% of his Attack stat[[/note]]; his Skill gives him a base 40% chance to trigger his Talent, with an additional 20% for each debuff his target has (meaning it is guaranteed if they have at least three debuffs). His Ultimate also applies Wiseman's Folly to his target, allowing any attack from other party members that hit the marked enemy to trigger his follow-up attack, up to two times. With his sixth Eidolon Resonance, ''Vincit Omnia Veritas'', Wiseman's Folly can be triggered one additional time, and the damage dealt by these follow-up attacks increases by 50%.
** His sixth-ascension Bonus Ability, ''Deduction'', increases his damage output against foes with at least three debuffs by 10% per debuff (hence 30% increase at minimum), capped at 50% (i.e 5 debuffs).

* CriticalHitClass: His Talent allows him to build up to ten stacks of Apotheosis, which boost his Critical Rate, for every foe he hits throughout the duration of battle.[[note]]Depending on Trace levels, by 1–2.8%, hence a maximum of 10–28%[[/note]] In addition, his second-ascension Bonus Ability, ''Piety'', automatically grants him one stack at the start of battle, while his first Eidolon Resonance, ''A Lacuna in Kingdom of Aesthetics'', adds a 4% Critical Damage boost to each stack (hence a maximum of 40%), and his fourth, ''Trumpet's Dedication'', allows him to gather two more stacks at the start of battle (hence three at optimal) as well as extends his stack capacity to twelve.[[note]]Meaning his maximum Critical Rate and Damage boosts grow to, respectively, 12–33.6% and 48%[[/note]]

* EncounterRepellent: His Technique inflicts "Daze" on nearby enemies in the overworld, which will make them stop pursuing you. Attacking them in this state will inflict damage on all enemies based on Argenti's ATK on the first turn, and recover 15 energy for him.

* LimitBreak: His schtick. Argenti can charge up his ultimate twice to unleash a much more powerful attack, denoted by an outer ring around the Ultimate gauge. The skill icon additionally starts out as a rosebud that blooms when the second energy level is met. The fully-charged Ultimate also [[RandomizedDamageAttack deals six additional damage bursts on a random foe]]. [[note]]Depending on Trace levels, its damage is equivalent to 96–172.8% of his Attack stat in its base form, 168–302.4% in its upgraded form, and the power of the random damage is equivalent to 57–102.6% of his Attack stat[[/note]]

* SimpleYetAwesome: Argenti isn't at all difficult to operate - Use his Skill to quickly gain Energy and stack his Crit Rate buff, then pop his Ultimate when it's completely filled for its bonus damage. ''Extremely'' effective.

Sparkle revels in chaos by encouraging her allies to use their Skills with reckless abandon through her Talent, ''Red Herring'', which increases the party's Skill Point pool by two as well as their damage output up to thrice for two turns whenever they consume SP. Her Skill, ''Dreamdiver'', summons a phantasmal carp that increases an ally's Critical Damage for one turn, as well as forwards their turn (except if used on herself); her Ultimate, ''The Hero with a Thousand Faces'', has her wear a fox mask that restores 4 SP as well as bestows the "Cipher" effect onto the party for two turns, which further bolsters her Talent's damage boost; and her Technique, ''Unreliable Narrator'', bestows the "Misdirect" effect onto the party, rendering them invisible to enemies and adding 3 SP at the start of battle.[[note]]When fully upgraded, she automatically increases the party's Attack stat, with increasing potency proportional to the number of her Quantum-type allies; her Talent can now add three Max SP, while its damage buff gains the ability to ignore a fraction of enemies' Defense proportional to the number of stacks; her Skill's Critical Damage buff is now extended to the start of the buffed ally's next turn, as well as also applied to allies with Cipher whenever she uses either her Skill or her Ultimate--the latter, if at least one ally is already buffed; and the Cipher effect is extended to three turns, as well as gains a direct Attack buff.[[/note]]

* ArmorPiercingAttack: Her second Eidolon Resonance, ''Purely Fictitious'', allows each stack of her Talent to allow the party's attacks to ignore 8% of enemy Defense (hence a maximum of 24%).

** Her Skill boosts an ally's Critical Damage for one turn, as well as [[CooldownManipulation advances their turn by 50%]] (unless used on herself).[[note]]Depending on Trace levels, equivalent to 12--26.4% of her own Critical Damage, with an additional 27--48.6%[[/note]]. Her fourth-ascension Bonus Ability, ''Artificial Flower'', extends its duration to the start of the buffed ally's next turn (hence bolstering [[OutOfTurnInteraction Ultimates and follow-up attacks]]), while her sixth Eidolon Resonance, ''Narrative Polysemy'', adds a further boost equivalent to 30% of Sparkle's own, as well as expands the buff on all allies endowed with Cipher whenever she uses either her Skill or her Ultimate (with at least one ally already buffed).
* CuteAndPsycho: Do not let Sparkle's cheery, childish personality and mannerisms fool you- she is an absolutely nasty piece of work that has a tendency to do things for her own entertainment, morals be damned.

* EncounterRepellent: Sparkle's Technique renders the party undetectable for 20 seconds, as well as adds 3 SP should they enter battle.

* HollywoodHypeMachine: [[https://youtu.be/IpuQvbTwCWU Her Myriad Celestia trailer]] suggests that "Sparkle" was originally a character a promising young actress played, before the constant string of performances (upwards to '''''990''''' fully-booked showings) eventually made her snap, [[BecomingTheMask adopting the "Sparkle" identity]] for real and becoming the Masked Fool she is today...that is, [[UnreliableNarrator assuming anything in it isn't another show she concocted to gather sympathy.]]

* MundaneUtility: Her Technique of giving her temporary stealth makes her one of the best characters for Trotter Catch in Simulated Universe: Expansion Module, as Trotters will not run from you and thus become absolutely trivial to catch. Sparkle's stealth can also be inherited by another character via switching, so you can team her up with a character with good mobility like Imbibitor Lunae or good offensive technique like Kafka to make the room even more of a joke.

* OohMeAccentsSlipping: In "Masquerade Duet", she directly voices all of the "Sweet Dreams Troupe" members that Sampo and Black Swan meet during their "murder investigation game." When Sampo is talking to the "Sheriff" that Sparkle likes to arrange her own death, "Sheriff's" voice slips up to Sparkle's own (angry) voice before "he" speaks normally again.

** [[spoiler: Although rude and aggressive in her first meeting with Aventurine, she seemed charmed enough that he actualy sort her out to leave him with a clue. While cryptic and delivered as an insult, Aventurine later admits it helped set him down the right path to achieving his aims on Penacony.]]
** [[spoiler: While approaching Sunday in the disguise of his dead sister was undoubtedly Sparkle twisting the knife, she seems to have been sincere about playing the role of Robin to keep up the masquerade for the Family, with Dr Ratio's later comment suggesting that its greatly helped the Family to pretend that everything is going smoothly for Robin's planned performance.]]

** Sparkle's second-ascension Bonus Ability allows her Skill's Critical Damage boost to carry over until the start of the buffed ally's next turn, hence enhancing their Follow-Up Attacks (as well as Ultimates). In the context of the Simulated Universe, where the path of Elation is centered around empowering such attacks, this means Sparkle's actively supporting her Path.
* SoftSpokenSadist: As one of the more radical members of the Masked Fools, Sparkle sees people's suffering as a toy for her own amusement and is shown to be an unrepentant sadist who loves to annoy people without ever raising her voice.

** Her Talent increases the party's SP pool from 5 to 7, as well as bestows up to three stacks of a damage boost for two turns whenever they consume SP[[note]]Depending on Trace levels, her Talent's damage multiplier is 3--6.6% per stack hence a standard maximum of 9--19.8%[[/note]] This makes Sparkle a fantastic companion to such SP-hungry damage-dealers like Qingque and Imbibitor Lunae.
** Aside from regenerating 4 SP, her Ultimate bestows the Cipher effect onto the party that further increases her Talent's damage buff for two turns.[[note]]Depending on Trace levels, by 6--10.8%, hence her Talent's damage boost raises up to 27--52.2%[[/note]] Her first Eidolon Resonance, ''Suspension of Disbelief'', extends its duration to three turns as well as adds a 40% Attack buff, while her fourth, ''Life Is a Gamble'', extends the SP regeneration to 5 points and raises the SP cap to 8.
* TwoFaced: Not her per say, but her fox mask is evenly split into white and red halves, which fits her trickster personality.

'''Type:''' [[CastingAShadow Quantum]]\\\

** [[spoiler: Sparkle repeatedly offers a prized possession as a gift, the 'Mutually Assured Destruction Button.' That she promises when pressed, will completely obliterate herself and the Penacony dreamscape. For a moment Aventurine is incredulous that she would be allowed to bring such a destructive device anywhere near Penacony, but then realises that with her outlandish claims and silly persona, it could actually be a case of CrazyEnoughToWork.]]

!Giovanni di Giorgio da Epsilon

[[folder: Hakuhatsu Ki]]

** Her sixth Eidolon Resonance, ''Apocalypse, the Emancipator'', increases her Resistance Penetration against all damage types by 20%, in addition to allowing her Basic Attack and Skill to [[AntiArmor shred through Toughness Gauges regardless of her foes' weaknesses]] and change the properties of these attacks such that they are considered Ultimate damage.

** Her Ascension voiceline says "Never turn back -- the path behind is gone." It's an oblique reference to one of Mei's victory quotes, "To move forward is my only choice."

[[folder:The Republic/Welkin Empire of Glamoth]]

''The Republic of Glamoth was, [[ExactlyWhatItSaysOnTheTin as the name suggests]], a republican-style government headquartered on the planet Glamoth.''

'''(The glorious [[InsistentTerminology Welkin Empire]] of Glamoth stretched tens of thousands of light-years across the stars, from its root upon the world for which it was named.)'''

''The Republic, once upon a time, became a target for the Swarm of Tayzzyronth, the next victim of THEIR spread across the cosmos.''

'''(The expansion of the fruits of civilization to the frontiers of the universe was halted by the raging insectoids, the hope of Glamoth nearly extingushed.)'''

''In their desperation, the Glamothi turned to genetic experimentation, creating the entity known as "Titania" and a military force for her to command: the Iron Cavalry Regiment.''

'''(And then one day, Her Majesty Empress Titania's gleaming, silver-white iron knights descended from the sky and drove back the invading Swarm. They took the fight to the enemy, swearing to preserve the Empire as a paradise for humanity for ever.)'''

'''(But the people began to fear. Were the Iron Cavalry becoming like their foe, blotting out the sun just like the vile Swarm had on that terrible day? And yet they fought on, fighting the foe that drowned out the stars themselves, bearing the hopes and dreams of an empire and their Empress.)'''

''The Iron Cavalry fought many desperate battles that created a literal ring of shattered mecha, ruined ships and butchered insectoids in the Glamoth star system. And when the guns finally fell silent, there was peace... for life on Glamoth was no more. By one hand or another.''

[[UnreliableNarrator ...Well, those narratives don't quite agree, do they?]]

The nation of Glamoth, whatever its true nature, was an interstellar state that came under massive attack from the Swarm - possibly prior, or adjacent to, the destruction of Tayzzyronth proper. It is most notable today for its leftover technology (which plays a role in the story of ''Star Rail'') and for the mystery surrounding its history - in-universe, sources disagree wildly on the nature of the state, the exact nature of the entities that defended it, and on how it reached its ultimate fate, with the matter being researched and debated by the Intelligentsia Guild to this day. You can learn much of the history of Glamoth via certain ornaments from the Simulated Universe, and the Trailblazer even has a chance to interact with a survivor of Glamoth in the main quest.

* ArchEnemy: The Swarm is outright described as such for Glamoth in one of the given narratives, and it's not hard to see why - both the extant narratives posit that the Swarm was dead-set on consuming Glamoth entirely and were the cause of untold suffering for the nation's people and their defenders.
* CoolSpaceship: The narratives agree that Glamoth did have the ability to build these, and they formed the backbone of the force that fought the Swarm. They also ended up forming a substantial part of the River of Death that now encircles Glamoth's home solar system.
* TheEmpress: Another point on which the existing history fragments disagree heavily. One describes "Empress Titania" as the head of state of Glamoth, commanding the fleets and worlds of the "Welkin Empire" in her glory and wisdom, with the Iron Cavalry reporting directly to her... and the other narrative describing Titania as the end result of Glamoth's genetic experiments, purpose-made to be the Cavalry's commander and otherwise an "Empress who holds no power". Which narrative is true, and just how "powerless" Titania would have been if people like Sam were willing to follow her orders, is a major point of interpretation.
* GoodRepublicEvilEmpire: ''Heavily'' played with. One of the history fragments, the one possibly written more from the perspective of Titania and the Iron Cavalry, describes the government as an Empire and, while portraying itself heroically, uses a lot of the sort of language that an "evil empire" might use in its own internal propaganda (down to outright "vowing to bring the fruits of civilization to all the barbaric borders" of the Empire). The fragment more from the perspective of the Intelligentsia Guild, outward looking in, identifies the nation as a Republic (and claims that the "Empire" was non-existant), but the descriptions of the Republic's methods of trying to preserve themselves are less than flattering and suggest, among other things, rampant human rights abuses in the creation of the {{Super Soldier}}s of the Iron Cavalry. The player is also provided with certain evidence that members of the Iron Cavalry were either lab-grown from conception or were recruited at a ''very'' young age. The true nature of the nation remains ambiguous and heavily up to interpretation, particularly the idea of elements of the depictions being more true or less true at various points in the struggle.
* HumongousMecha: Some of the language used in the existing history fragments suggests Glamoth may have used larger machines alongside the PoweredArmor suits which we can still see an example of today, but it's unclear what the exact nature of the "mecha" were or if this just refers to the armors under a different term.
* KnightInShiningArmor: The more propagandistic of the existing narratives presents the Iron Cavalry as this outright, calling them "silver-white iron knights" and saying "their arrival was like a gift from the gods, bringing the light of day back to the human world". Sam, for his part, laments that he mostly serves as an engine of destruction these days, and would like to be seen in a less violent light more in line, perhaps, with this ideal.
* PoweredArmor: The surviving example of Glamoth "mecha" we see in the game is this, and is similar in proportion, form and function to a [[Anime/TekkamanBlade Tekkaman]] and/or a [[VideoGame/{{Warframe}} Warframe]], with some elements of a Franchise/KamenRider as well. Although it is not HumongousMecha-sized, the example we see is still easily seven feet tall or more.
* SuperSoldier: One place the narratives agree, and that you can see in action with Sam in a few of the trailers, was that the military of Glamoth ended up dominated by soldiers of this sort, formed into the Iron Cavalry Regiment. The one living example we see employs a suit of PoweredArmor which is both incredibly adept at physical combat and exerts incredible control over fire and ignition. If Sam is representative of the power of the average Cavalryman, the Iron Cavalry were an incredibly potent military force.
* UnreliableNarrator:
** Pretty much the main gimmick of Glamoth in the game proper. The items that provide the bulk of their lore (the two pieces of the "Firmament Frontline: Glamoth" ornament set from Simulated Universe World 8) outright contradict each other in their narratives and details, and the "Glamoth's Silent Tombstone" Link Rope notes that the veracity of the narratives and how Glamoth met its end is heavily debated among historians of the Intelligentsia Guild in the present day. Between the items, and some other information you're provided from another source, it's possible to piece together a narrative of what might have happened, but the details are still left up to the player to interpret.
** From the narratives provided, even the more "neutral" Intelligentsia Guild-flavored one, it's also unclear precisely ''when'' this happened. Given the strength of the Swarm as described in both narratives, it seems as if Glamoth must have come under attack from the Swarm while Tayzzyronth was still active, but THEY apparently died ''thousands'' of years ago. And even if the conflict happened after Tayzzyronth perished, the conflict is sufficiently separated from the current day that the exact events are heavily contested, and very few eyewitnesses remain. So when exactly this all happened, and how Sam could still be alive after all that time, remains another matter of speculation and interpretation.

A full listing of tropes concerning Sam can be found in his folder on the Characters/HonkaiStarRailStellaronHunters page. Note that this folder does contain spoilers for the ''Star Rail'' main Trailblaze Quest for Penacony.

'''(The glorious Welkin Empire of Glamoth stretched tens of thousands of light-years across the stars, from its root upon the world for which it was named.)'''

* CompositeCharacter: its Basic Attack is an [[HerdHittingAttack AOE attack]] like Trotter of Destruction, while its Skill is a [[HealingHands whole party heal]] like Trotter of Abundance. Its Ultimate is a SuperMode that adds the property of its skill into its basic attack, in addition to buffing all allies' damage output for 20% for a turn.

* TheReveal: the event organizer, Wilder, later reveals that [[spoiler:this Aether Spirit was part of Asta's collection, and that its "lifelike quality" is because of an anomaly that occurred when uploading its data during its creation; somehow, its data was uploaded completely instead of selectively, hence how it acts life-like and almost sentient.]]
* StarterMon: it becomes the first Aether Spirit that you acquire in the event's story, and it'll be a major focus of the story as the Traiblazer's SignatureMon.
* StatusBuff: its Talent is to increase the ATK of other party members for a turn after it takes a hit.

* RevolversAreJustBetter: He wields a futuristic revolver that can transform into a laser HandCannon as his primary weapon.

Acheron sends her foes to oblivion with swift, precise swordsmanship. Her Talent, ''Atop Rainleaf Hangs Oneness'', allows the party to simultaneously build one stack of Slashed Dream for Acheron and one of Crimson Knot onto their foes whenever they inflict debuffs (to a maximum of nine each), with the latter prioritizing building stacks upon the foe with the most such stacks, receiving them should the inflicting attack hit multiple foes, as well as inheriting stacks from another marked foe should they fall. For her part, Acheron can build both stacks through her Skill, ''Octobolt Flash'', where she slashes onto her foes and leaves afterimages that hack away immediately after. Once she has nine stacks of Slashed Dream, her Ultimate, ''Slashed Dream Cries in Red'', is unlocked, during which she traps all her foes in a monochrome dimension and inflicts them with penalties to all kinds of type resistance, then hacks away at one foe at a time with three strikes of ''Rainblade'', each of which consume up to three Crimson Knots to be able to damage adjacent foes (and whose potency increases proportional to the number of stacks consumed), before ending with a reality-shattering ''Stygian Resurge'' slash on all foes that clears all remaining Knots. In addition, her Technique, ''Quadrivalent Ascendance'', is a swift slash that instantly defeats normal enemies, while against elite- or boss-grade foes and Trotters, it damages all foes at the start of a new wave and chips at their Toughness Gauges regardless of resistances, and grants her a same-named buff that automatically builds a stack of Slashed Dream and Crimson Knot (on a random foe) after using her Ultimate.[[note]]When fully upgraded, she automatically builds a stack of both kinds at the start of her turn, as well as gains a boost to raw damage proportional to the number of fellow Nihility Pathstriders in her party and to Critical Rate when attacking debuffed enemies; new enemies that enter battle suffer greater damage whenever she uses her Ultimate; she automatically gains five stacks of Slashed Dream and Crimson Knot (against a random foe) at the start of battle, as well as up to three stacks of her Technique's buff whenever she builds Slashed Dream beyond the maximum; the preliminary slashes of her Ultimate allows her her to build up to three stacks of a damage boost that last for three turns afterwards whenever she attacks foes afflicted with Crimson Knots, while its finisher is augmented with six additional strikes; and all her attacks can now shred Toughness Gauges regardless of enemy resistances.[[/note]]

** Her sixth Eidolon Resonance, ''Apocalypse, the Emancipator'', increases her Resistance Penetration against all damage types by 20%, in addition to allowing her Basic Attack and Skill to [[[[AntiArmor shred through Toughness Gauges regardless of her foes' weaknesses]] and change the properties of these attacks such that they are considered Ultimate damage.

* GatheringSteam: Besides inflicting Crimson Knots on debuffed foes, Acheron can build up to nine stacks of Slashed Dream to unlock her Ultimate. In addition, her second-ascension Bonus Ability, ''Red Oni'', instantly builds five stacks of both kinds at the start of battle (the Knots on a random foe), as well as allows her to build up to three stacks of that conferred by her Technique (see "ResourceReimbursement" below) whenever she tries to gather Slashed Dream beyond its maximum nine stacks (hence automatically reimbursing three stacks of Slashed Dream for herself and Crimson Knot on a random foe after using her Ultimate).

* {{Ronin}}: As a wandering swordswoman from a lost world with a Japanese cultural motif, Acheron fits the role in all but name.

* SheathStrike: Her announcement post mentions that she always strikes with her scabbard without drawing her sword, as shown in [[spoiler:her fight with Sam]] where she swings it despite not removing it from its sheath. Despite this, the "White Night" music video has her wielding her sword without said scabbard. Her basic attack has her swing her blade onto enemies while it's still sheathed.

* SwordBeam: She launches several while fighting Sam during the ''White Night'' music video announcing v2.0, [[spoiler:and sends a single giant red slash towards Aventurine that shatters his domain along with him in the climax of the ''Cat Among the Yawning Pigeons'' Trailblaze Mission]].

** Her Basic Attack has a additional 50--68% chances of inflicting more Arcana for each damage-over-time debuff (i.e., Wind Shear, Burn, Bleed, Shock) active on her target. Her second-ascension Bonus Ability, ''Viscera's Disquiet'', gives her Skill a 65% base chance to also inflict Arcana in a like manner.

Black Swan condemns enemies afflicted by damage-over-time debuffs with up to fifty stacks of Arcana imposed by her Talent, ''Loom of Fate's Caprice'', which explode at the start of their turn before resetting to one stack, in addition to expanding its damage radius to adjacent foes (also with a chance to inflict Arcana) if they have at least three stacks and allowing damage-over-time debuffs to ignore a fraction of their Defense with at least seven. For her part, Black Swan can inflict at least one stack through her Basic Attack, ''Percipience, Silent Dawn'', which has additional infliction windows depending on the number of her target's Wind Shear, Bleed, Burn, and/or Shock debuffs; one a time with her Skill, ''Decadence, False Twilight'', where she drops down a magic circle on her target and adjacent foes, with an additional chance to inflict a Defense penalty for three turns; and repeatedly at the start of battle on all eneimes with her Technique, ''From Façade to Vérité'', with decreasing chances for every stack successfully imposed. Her Ultimate, ''Bliss of Otherworld's Embrace'', summons phantasmal arms to squeeze the life out of all her foes, as well as imposes Epiphany for two turns, which increases their damage intake during their turn and simultaneously counts their Arcana damage as Wind Shear, Bleed, Burn, and Shock effects, as well as negates the first Arcana stack reduction whenever it is triggered.[[note]]When fully upgraded, she gains a chance to automatically impose stacks of Arcana, whenever her Skill hits enemies afflicted with damage-over-time debuffs, a new foe enters the field, or whenever they are attacked (with an additional window should they manually trigger such debuffs), as well as impose a penalty to her foes' Wind, Physical, Fire, and/or Lightning Resistances if they have the corresponding debuffs; defeating enemies afflicted with Arcana has a high chance to impose six stacks on adjacent foes; and the Epiphany effect imposes an Effect Resistance penalty, as well as restore some of Black Swan's Energy either at the start of the afflicted's turn or whenever they are defeated.[[/note]]

* DamageOverTime: Black Swan has her own unique form of such an effect called Arcana, which stacks up to fifty times and explodes to deal Wind damage at the start of the afflicted enemy's turn before the stacks are reset to one, and whose potency is tied to her Talent's Trace levels. Black Swan has a chance to manually impose the stacks--one at a time with her Basic Attack (depending on Trace levels)[[note]]By 50--68%[[/note]], on her target and adjacent foes with her Skill (a 100% base chance), and repeatedly on all foes at the start of battle with her Technique (a 150% base chance, with a 50% reduction to success rate for each time a stack is successfully imposed)--and when the enemy's turn comes up, each active damage-over-time debuff an enemy has also has a chance to impose stacks (again tied to her Talent) before Arcana deals damage.[[note]]Depending on her Talent's Trace levels, the infliction rate of Arcana per each damage-over-time debuff is 50--68%, and base damage is equivalent to 96--264% of her Attack stat, with a 4.8--13.2% damage multiplier per stack (hence a maximum of 240--660%)[[/note]] Furthermore, her sixth Eidolon Resonance, ''Pantheon Merciful, Masses Pitiful'', gives her a 65% chance to inflict Arcana on any foe attacked by her allies, with another 50% chance to inflict an extra stack for each one she is applying onto enemies (from any source).

* MythologyGag: Her role in the Fables About the Stars trailer is remarkably similar to that of Dainsleif in VideoGame/GenshinImpact's [[https://www.youtube.com/watch?v=TAlKhARUcoY Teyvat Chapter Storyline Preview]], that of a mysterious narrator who provides descriptions and {{Foreshadowing}} of the future characters and plotlines.

* NightmareHands: Her Ultimate has her summon a horde of sinister glass hands to crush all enemies in their grasp[[note]]Depending on Trace levels, damage is equivalent to 72--129.6% of her Attack stat[[/note]], as well as impose Epiphany for two turns, which [[DamageIncreasingDebuff increases her victims' damage intake during their turn]] (e.g., damage-over-time or Arcana activation) for the next two turns[[note]]Depedning on Trace levels, damage multiplier increases by 15--27%[[/note]], negates the stack reset of the first Arcana damage, and [[LiteralWildCard makes Arcana count as Wind Shear, Bleed, Burn, and Shock effects for any ability that involves them]] (such as Luka's enhanced Basic Attack, which triggers Bleed damage, or Hook's Burn-based abilities).

* OhCrap: When Black Swan tries to peer into Acheron's memories, she is utterly horrified by whatever it is she saw and later admits she made a terrible mistake in trying to view the Galaxy Ranger's past.

* PercentBasedValues: Her sixth-ascension Bonus Ability, ''Candleflame's Portent'', increases her damage output equivalent to 60% of her Effect Hit Rate, to a maximum of 72% (i.e., if said stat is at least 120%).

** Her Skill hits a target and adjacent foes[[note]]Depending on Trace levels, damage is equivalent to 45--99% of her Attack stat to all affected foes[[/note]], with a 100% base chance to inflict a stack of Arcana and also a 100% rate to inflict a [[DamageIncreasingDebuff Defense penalty]] for three turns.[[note]]Depending on Trace levels, by 14.8--22%[[/note]]
** If an enemy has at least three stacks of Arcana when their turn comes up, it'll additionally trigger a blast that deals damage to adjacent enemies and inflict 1 stack of Arcana on them.[[note]]Depending on her Talent's Trace levels, splash damage is fixed as equivalent to 72--198% of her Attack stat, and the Arcana infliction rate is 50--68%, identical to the regular rate[[/note]]

** Her Basic Attack has additional chances of inflicting more Arcana for each damage-over-time debuff (i.e., Wind Shear, Burn, Bleed, Shock) active on her target[[note]]Depending on Trace levels, the chance is 50--68% each[[/note]]. With her 2nd ascension Bonus Ability, ''Viscera's Disquiet'', her Skill will also gain this trait, with 65% base chance.
** Her fourth-ascension Bonus Ability, ''Goblet's Dredges'', gives her 65% base chance to automatically inflict a stack on new enemies that enter the field, as well as gives the party's attacks that manually triggers damage-over-time debuffs (e.g., Kafka's Skill) a 65% base chance to inflict up to three stacks of Arcana at a time (one for each DOT debuffs triggered).

* WildCard: [[spoiler: For the sake of solving the mystery of Penacony, Black Swan is willing to ally with multiple of the involved factions. This includes striking up an alliance with Aventurine, before also making one with the Nameless out of both faith in their abilities and as part of her deal with Aventurine, who wanted the [[PlayerCharacter Trailblazer]] brought to him to strike a deal.]]
