Glossary

The recurring terms of Teyvat, explained — the words the story assumes you remember.

AbyssAbyssal: The dark realm beneath and beyond Teyvat, Celestia's opposite, whose power corrupts almost anything it touches. Its taint is what maddened Dvalin in the prologue, and its monsters keep resurfacing from Mondstadt all the way to Natlan.
Abyss HeraldBosses: An elite Hydro-wielding commander of the Abyss Order, cloaked and masked in Khaenri'ahn fashion. Dainsleif hunts one through Liyue and another into the Chasm; cornering the first in Jueyun Karst is what finally brings the Traveler face to face with their own sibling.
Abyss LectorBosses: The spellcasting priest-rank commander of the Abyss Order, counterpart to the Abyss Herald. One of them activates the device deep in the Chasm meant to strip Khaenri'ah's curse away, which instead tortures every cursed soul at once; Halfdan dies stalling it before the Traveler destroys both Lector and machine.
Abyss MageBosses: The hooded elemental spellcasters that make up the Abyss Order's rank and file, each sheltered behind a shield of its own element. One of them turns the newly summoned Dvalin against the party at Starsnatch Cliff and leaves the Holy Lyre in pieces; another, run down at Diluc's winery, releases in death the energy that shows Venti what has been severing his bond with the dragon.
Abyss Orderthe Order: The organized faction of the Abyss, led by the Traveler's own missing sibling and made up largely of cursed survivors of Khaenri'ah. Their goal is revenge on Celestia and the gods for the Cataclysm, which makes them the story's most persistent antagonist.
Adeptiadepti · Adeptus: Liyue's illuminated beasts — long-lived, semi-divine guardians such as Xiao and Cloud Retainer who fought for Rex Lapis in the Archon War. They mostly keep to Jueyun Karst now, and their uneasy standoff with the human Qixing shapes the Liyue chapter.
Akasha SystemAkasha · Akasha Terminal · Akasha Terminals: Sumeru's network of ear-worn terminals that feeds knowledge straight into people's minds, created by the Dendro Archon and controlled by the Akademiya's sages. The sages secretly used it to harvest dreams and wisdom from the population, and control of it is what the Sumeru coup is fought over.
All-Devouring NarwhalBossesnarwhal: The star-devouring leviathan of the Primordial Sea, first glimpsed circling above Childe as he drifts awake in its depths. It surfaces as Fontaine's prophesied doom and tears into the Opera Epiclese during Furina's trial, and the Traveler destroys it wielding Neuvillette's restored Sovereign authority.
Ancient NameAncient Names: An obsidian stone carrying a title such as hope or resilience, granted to chosen members of Natlan's tribes and bound to their soul. It anchors the bearer in the Night Kingdom after death, and forging one for an outsider like the Traveler is the Natlan chapter's central task.
ArchonArchons · The Seven: One of The Seven gods who rule Teyvat's nations, each holding an element and a Gnosis. They won their thrones in the Archon War and answer to Celestia — an arrangement the story steadily reveals to be far more fragile, and far more resented, than it looks.
Armory PalacePlaces: The Snezhnayan weapons institution buried deep in Glupov, managed by the Harbinger Sandrone and answering to the Fatui. Its reach shows early — one of its guards is hunting the researcher Mitya inside the Korolevskiy Theater while the deaths there begin. The Snezhnaya chapter breaks off on Pierro carrying the ailing Paimon there, with the Traveler and Odette racing after him.
BeishtBosses: A colossal sea beast and Osial's consort, roused from the depths to tear down the newly rebuilt Jade Chamber. This time Liyue faces the sea without a single adeptus — the Millelith, Keqing, Ganyu and the Crux Fleet hold the line — and it is Shenhe, breaking free of her own bound hatred, who drives the creature back into the deep.
Black Serpent KnightsBosses: Khaenri'ah's royal guard — Dainsleif's own former subordinates, their minds long eroded, still obeying the last order he gave them five hundred years ago. They guard the cursed hilichurls who come to the Chasm to die, and one of them, the elite guard Halfdan, has kept enough of himself to give his life for that order.
Cataclysmcataclysm: The disaster 500 years ago in which Celestia destroyed Khaenri'ah and monsters overran Teyvat, killing gods and reshaping every nation. Nearly every long-lived character — Dainsleif, Capitano, Rukkhadevata, Zhongli — is defined by what they did or lost in it.
Celestia: The island floating in Teyvat's sky where the gods are said to dwell, and the authority that hands out Visions and installs Archons. It almost never acts openly, and much of the later story is about characters like Focalors and Neuvillette working around it without being noticed.
Court of FontainePlaces: Fontaine's capital, a city of machinery and public trials built around the Opera Epiclese, where Furina holds court as Archon. The Traveler is received there with a staged public welcome that says everything about how this nation does politics. Its courts' authority stops dead at the Fortress of Meropide, which is precisely why Childe could vanish out of a cell in it.
DelusionDelusions: A Fatui-made counterfeit Vision that grants elemental power to anyone, but burns through the user's own life force to do it. Handed out to Inazuma's resistance during the Vision Hunt Decree, Delusions killed their wielders — Teppei dies of his in front of the Traveler.
DescenderDescenders: A being from outside Teyvat, not bound by its laws and able to change its fate — the Traveler and their sibling are two of them. Teyvat's gods once fought a war against the Descenders, which is why the Traveler's mere presence makes the powers above nervous.
Divine Knowledge CapsuleItems: A glowing red capsule said to hold the wisdom of the gods, distilled by the Akademiya from scholars who went mad linking their minds to Irminsul. The stolen one drives the Eremite leader Mizri berserk, hinting at the sages' real plan — pouring such capsules into Scaramouche to manufacture a god — and Alhaitham quietly pockets the evidence.
Dragon SovereignDragon Sovereigns · Seven Sovereigns · Hydro Sovereign · Dendro Sovereign: One of the seven dragons who ruled Teyvat's elements before the Heavenly Principles arrived and carved their authority up to create the Archons. Neuvillette is the reborn Hydro Sovereign and Apep the Dendro one, and Neuvillette reclaiming his full authority is what saves Fontaine.
Draught of LucidityItems: A cure for Abyssal corrosion developed during the Cataclysm by Guthred, a Khaenri'ahn military doctor who tested it on himself and died completing it. Capitano carries the last of it and spends it on the Natlan child Ocotlan — the moment that lets him unmask before the Traveler and admit the grudge he has nursed against the death-god Ronova ever since.
ExuviaItems: The corpse Rex Lapis left behind when he staged his own death at the Rite of Descension — a shed divine husk rather than a real body. The Qixing lock it away in the Golden House, and reaching it is the true object of Childe's entire Liyue operation. When he finally plunges a hand into it he finds no Gnosis inside, because Morax is very much alive.
Eye of GraeaeItems: An ancient device the Traveler awakens alone in Snezhnaya's everwinter, which then travels with them as a companion. It re-arms them inside the Shadow Realm — a void where wind and the elements simply do not work — and is therefore the reason the Traveler can fight at all in the one nation that strips their usual power away.
Fatui: Snezhnaya's diplomatic corps and de facto army, serving the Cryo Archon known as the Tsaritsa. Officially they are envoys; in practice they steal Gnoses, run banned experiments and destabilize every nation the Traveler sets foot in.
Fatui HarbingerHarbinger · Harbingers · Fatui Harbingers · Eleven Fatui Harbingers: One of the Eleven, the Tsaritsa's elite officers, ranked by number and vastly more dangerous than ordinary Fatui. Signora, Tartaglia, Scaramouche, Dottore, Capitano, Arlecchino, Pantalone and Columbina each drive a large chunk of the main story.
Field TillerItemsField Tillers: The prototype Ruin Guard lying dormant in Stormterror's Lair, and the original name of the machines Khaenri'ah built as its mortal weapons — the wandering Ruin Guards of the present day are its descendants. The Abyss Order means to crown a defiled Statue of The Seven with its eye to assemble a mechanized god; Dainsleif extracts the eye and keeps it instead of destroying it.
FontainePlacesFontainian · Fontainians: The nation of justice, a land of courts, machines and public trials that worshipped the Hydro Archon Focalors. Its people are not human at all but descendants of Oceanids, condemned by an old divine judgment to dissolve back into the Primordial Sea — the prophecy the whole chapter races to avert. Focalors' answer was a five-hundred-year performance — she split off the human Furina to play the Archon, then had herself executed by her own Oratrice, shattering the Hydro throne and voiding the sentence.
Fortress of MeropidePlacesMeropide: Fontaine's underwater prison, sunk beneath the sea and so self-governing that the Court of Fontaine holds no jurisdiction inside it. Administrator Wriothesley runs it on a coupon economy and a set of whispered "hidden rules"; the Traveler gets sentenced to forty-five days there to find out how Childe vanished from a sealed cell. At its lowest level lies a sealed breach into the Primordial Sea, and the water rising behind that seal is the prophecy arriving.
Foul LegacyBossesFoul Legacy Transformation: The demonic battle form Childe brought back from the Abyss, which clads him in the armament of a Demon King. He unleashes it in the Golden House after finding no Gnosis in the Exuvia — and loses anyway, which is what pushes him to wake Osial instead.
Fountain of LucinePlaces: The fountain in front of the Opera Epiclese where Fontainians throw coins and make wishes, and in which all the nation's water is said to gather. Furina's tears go into it unnoticed for five hundred years, and it is where the Traveler meets the Oceanid who proves the missing girls were dissolved into water rather than murdered.
GnosisGnoses: A chess-piece-shaped stone that marks one of The Seven as an Archon and links them to Celestia. It is the source of their divine authority, and the Fatui spend the whole story collecting them on the Tsaritsa's orders.
Golden HousePlaces: The vault beneath Mt. Tianheng where all of Teyvat's Mora is minted, and where the Qixing hide the Exuvia after Rex Lapis's apparent death. It is the stage for the Traveler's duel with Childe and for the discovery that the Geo Gnosis is missing from the corpse; once Zhongli hands that Gnosis to the Tsaritsa, the mint falls silent for good.
GosoythothBossesLord of Eroded Primal Fire: The Abyssal leviathan behind the invasion of Natlan, whose corrosion leaves survivors trapped in trauma and hallucination long after the fighting stops. Mavuika faces it in the depths of the Night Kingdom, and only the Traveler's Ancient Name and the Lord of the Night's blessing of Pyro are enough to destroy it for good.
Guyun Stone ForestPlacesGuyun: The archipelago of stone pillars off Liyue's coast, said to be the lances Rex Lapis drove through the sea god Osial, who has lain sealed beneath it ever since. When his duel with the Traveler goes wrong, Childe uses replicated Sigils of Permission to raise Osial from there, nearly costing Liyue Harbor its existence. It is also where Beidou's Alcor lies at anchor when the Traveler books passage to Inazuma.
Heavenly Principles: The supreme authority above Celestia that overthrew the dragon Sovereigns and installed the Archons in their place. It has not visibly stirred in centuries — not even when Fontaine's Hydro throne was destroyed — and confronting it is the stated endgame of the Traveler's sibling.
Heretic of the False MoonBosses: The monstrous form Dottore assumes once he fuses with the artificial Moon Marrow, wielding the stolen authority of a moon he forged himself. He lays siege to Nasha Town and executes Sandrone when she shields the Traveler from his killing blow; only the reborn Trilune Goddess and the Traveler together can shatter the Marrow and end him.
Holy Lyre der HimmelItemsHoly Lyre: The relic lyre kept in Mondstadt's cathedral, said to have belonged to Barbatos himself. Venti needs it to play the song that soothes Dvalin, which is why the Prologue detours into stealing it back from the Church.
InazumaPlacesInazuman: The storm-sealed island nation of eternity, ruled by the Electro Archon Raiden Shogun through her Shogunate and closed to the outside world. Its pursuit of an unchanging Eternity produces the Vision Hunt Decree and the civil war that follows, because the Shogun enforcing it is only a puppet — the real Ei withdrew into the Plane of Euthymia after losing her friends in the Cataclysm. Defeat at the Traveler's hands drags her back out, and she repeals the decree and reopens the borders.
Irminsul: The vast white world tree that stores every memory and record in Teyvat, fed by the Ley Lines. Editing Irminsul edits reality itself — Nahida uses it to erase Rukkhadevata from history, and the Withering is a sickness in its roots.
Jade ChamberPlaces: Ningguang's floating palace above Liyue, from which the Qixing watch over the whole region and the Tianquan holds court. To save the harbor she drops it out of the sky onto Osial — the largest sacrifice any mortal makes in Liyue's story — and the Interlude chapter is about rebuilding it with mortal hands alone.
Jueyun KarstPlaces: The cloud-wrapped peaks where Liyue's adepti live, which mortals normally do not dare enter without a Sigil of Permission. Childe sends the Traveler there to clear their name after Rex Lapis's death by winning the adepti's trust, and the round of Xiao, Mountain Shaper and Cloud Retainer is what first exposes how far the adepti and the Qixing have drifted apart. The Traveler later hunts Abyss Order cells around it alongside Dainsleif.
Khaenri'ahKhaenri'ahn · Khaenri'ahns: An advanced underground kingdom that had no god and no Visions, destroyed by Celestia in the Cataclysm 500 years ago. Its survivors were cursed with immortality or twisted into hilichurls, and their grudge is what fuels the Abyss Order, Dainsleif and the Five Sinners.
Ley LinesLey Line · Leyline · Leylines: The invisible channels of elemental energy running through Teyvat that feed Irminsul and record everything that happens along the way. Damage or re-weave them and you can erase memories or reshape a whole nation — exactly what the Night Kingdom and the Loom of Fate are built to do.
LiyuePlaces: The nation of contracts in Teyvat's east, sworn to the Geo Archon Morax and run day to day by the merchant council of the Qixing. Its chapter opens with the Archon falling dead from the sky at the Rite of Descension — a death he staged himself as one final contract, to see whether Liyue could govern itself without a god. It could, so he handed his Gnosis to the Tsaritsa and stayed on among mortals as the consultant Zhongli.
Liyue HarborPlaces: Liyue's great port city and the seat of the Qixing, watched over by the half-adeptus Ganyu for 3,700 years. The Traveler arrives just in time to watch Rex Lapis fall dead from the sky at the Rite of Descension, and the harbor is what everyone spends the chapter fighting over — nearly drowned when Childe raises Osial offshore, until Ningguang drops the Jade Chamber on him. The Interlude returns here for the rebuilding, decided by mortal hands alone.
Loom of Fatethe Loom: The Abyss Order's machine for weaving Ley Lines, built on the implanted memories of the cursed child Caribert and capable of rewriting reality itself. The Traveler's sibling uses it to remake Khaenri'ah, and the false idyll of Vimara Village was one of its early runs.
MondstadtPlaces: The city of wind and freedom, and the first nation the Traveler reaches. It has no ruler by design — Barbatos handed his authority to its people and left the Knights of Favonius to keep order in his absence, which is why its crises tend to be solved by whoever happens to care enough.
Moon MarrowItemsMoon Marrows · Marrows: The energy core left behind when one of Teyvat's three moon goddesses dies, carrying the imprint of her divinity. Columbina's countermove in Nod-Krai is to gather all three and restore her own power, which is what the Fatui ultimatum to Lauma's people is really about — until Alice reveals the plan is worthless, because Columbina has no true name to anchor it.
NatlanPlaces: The volcanic nation of war in Teyvat's west, where six tribes fight under Mavuika, a human Pyro Archon rather than a born god. All its wars are really one war — the Abyss devouring the souls kept in the Night Kingdom — and Mavuika burned herself into the Sacred Flame five centuries ago so she could return for the one moment that war could be won. Winning it costs her her Archon power and Capitano his existence, and it tears open the false sky Celestia hangs over Teyvat.
Night Kingdom: The afterlife realm the Lord of the Night wove out of Natlan's shattered Ley Lines, where the souls of Ancient Name bearers are kept and can be called back to fight. Restoring Natlan's real Ley Lines would erase it — souls, history and all — and that dilemma drives the whole Natlan chapter.
Nod-KraiPlaces: An autonomous borderland at Snezhnaya's southern edge that has no Archon of its own, ruled instead by feuding factions, Fatui garrisons and the pull of the moon. Its Scions worship the moon goddess Kuutar, and the region's whole history is bound to the three moons that once hung over Teyvat, whose relics everyone in Chapter VI is hunting. It ends with Columbina inheriting the Three Moons' authority as the Trilune Goddess and Dottore destroyed — after which his last surviving segment carries the fight into Irminsul and Sumeru.
OchkanatlanPlaces: The buried remnant of an ancient Natlan civilization of the same name, which the Abyss Order takes over as its headquarters. Capitano fuses his existence with the Lord of the Night here to pay Ronova's price in Mavuika's place, taking Xbalanque's seat and remaining as the Night Kingdom's silent guardian. It is also where Dainsleif and the Traveler storm the Order, only to learn its whole army was thrown away as bait for Dainsleif's memories of Khaenri'ah.
Opera EpiclesePlacesopera house: Fontaine's opera house on Erinnyes, which doubles as the nation's chief courthouse — the Oratrice stands behind the stage and pronounces every verdict. Lyney's magic show there opens the chapter and turns straight into a murder trial. On the same stage Furina is later prosecuted by the Traveler, exposed as no god at all, sentenced to death by the Oratrice anyway — and the All-Devouring Narwhal tears in through the roof.
Oratrice Mecanique d'Analyse CardinaleItemsOratrice: Fontaine's judicial machine, which pronounces every verdict in the Opera Epiclese and is held to be infallible. It is really a device that converts the nation's faith in justice into raw energy, and the hiding place of Focalors' divine will — which is why it can sentence the "Hydro Archon" to death and have the sentence stand.
OsialBossesOverlord of the Vortex: An ancient sea god whom Rex Lapis defeated and pinned beneath Guyun Stone Forest millennia ago. Childe frees him to force a crisis severe enough to summon Liyue's adepti, and stopping him costs Ningguang the Jade Chamber.
OutlanderOutlanders · outlander · outlanders: What people in Teyvat call anyone who comes from beyond the world — in practice, the Traveler. Outlanders stand outside Teyvat's rules, which is why Natlan's Ancient Names and its Statue of The Seven are not supposed to work on them at all.
Phlogiston: Natlan's local energy, an advanced form of Pyro that responds even to people without a Vision — including the Traveler, whom the Statue of The Seven refuses. It powers the tribes' technology and turns out to be programmable matter left behind by the dragons.
Pilgrim's ChronicleItems: A vessel of "memory" granted by the Lord of the Night, needed because Natlan's Ley Lines do not record the deeds of outsiders. Xilonen and Citlali obtain it so the Traveler's Ancient Name can be forged at all — and so that what the Traveler does will survive even if Mavuika, who is fated to die, is not there to witness it.
Primordial SeaPrimordial Seawater: The ancient sea beneath Fontaine where all life in Teyvat began, whose water dissolves anyone descended from Oceanids. Its rising level is the apocalypse Fontaine spends its whole chapter racing to stop, and its authority once belonged to the Hydro Dragon.
Sacred FlameItems: The eternal fire burning in Natlan's Stadium of the Sacred Flame, into which Mavuika burned herself five hundred years ago so she could return at the one moment the Abyss could be beaten. It fuels the Ode of Resurrection that brings fallen Ancient Name bearers back, and its slow guttering is the clock ticking behind the whole Natlan chapter.
Samsarasamsara · samsaras: A looped dream that resets over and over, used by Sumeru's sages to trap a whole city inside one endless festival day. Nahida later turns the same trick on Scaramouche; escaping a samsara starts with noticing that the loop exists at all.
Sanctuary of SurasthanaPlaces: The treetop palace above the Akademiya where Sumeru's Dendro Archon resides — and where the sages kept Nahida sealed away from her own nation for five hundred years. Alhaitham's whole coup is engineered to get the Traveler close enough to wake her imprisoned consciousness, and when she finally walks out of it, Sumeru has an Archon again.
Shades: Four primordial beings the Heavenly Principles created out of itself to fight the dragons — Ronova, ruler of death, Istaroth of time, Naberius of life, and the Ruler of Space. They almost never appear in person, but it is their permission that lets Nahida act at the climax of the Nod-Krai arc.
Shouki no KamiBossesEverlasting Lord of Arcane Wisdom: The colossal Fatui mecha the Akademiya's sages built as the vessel of their manufactured god, with Scaramouche installed at its heart. The Traveler brings it down with the compiled knowledge of Sumeru's people; much later, when Nahida gives Scaramouche his memories back, the machine rears up one final time out of his pain and he destroys it himself.
Sigil of PermissionItemsSigils of Permission: A token that lets its bearer walk safely into the adepti's domain in Jueyun Karst, which mortals may otherwise only worship from the edges. Childe hands one to the Traveler in Act I as a gesture of goodwill; two acts later he uses replicated Sigils of Permission to break the seal on Osial, turning a small courtesy into the trigger for Liyue's near-destruction.
SinnerSinners · Five Sinners · Five Sinners of Khaenri'ah: One of the Five Sinners of Khaenri'ah, the figures blamed for the kingdom's destruction — among them Rhinedottir the alchemist called Gold, Vedrfolnir the Visionary and the moon-obsessed Rerir. They surface one at a time as the oldest and most dangerous players behind the Abyss Order.
SnezhnayaPlaces: The frozen northern nation of the Cryo Archon known as the Tsaritsa, and the home of the Fatui who have been collecting Gnoses for her since the Prologue. Its everwinter is a rationed one — under Project Stuzha warmth is metered out and villages freeze, while underground societies like Rokot work against the Fatui. The Traveler finally crosses the border to find the Tsaritsa gone east to war and the Shade Ronova staging a play in the capital, quietly killing anyone whose ideas threaten the Heavenly Principles.
Stadium of the Sacred FlamePlacesstadium: Natlan's great arena, where the six tribes settle their contests before the eternal fire itself. Kachina fights her way through the bracket here to earn a place in the Night Warden War, and Mavuika steps down from its stands to welcome the Traveler she has been expecting. Capitano later storms it to take the Pyro Gnosis, and it is where Xilonen finally begins forging the Traveler's Ancient Name.
Statue of The SevenStatues of The Seven: The Archon statues standing in every region; touching one grants the Traveler that nation's element and revives their party. They are Celestia's local outposts as much as landmarks, which is why Natlan's statue refusing to grant Pyro is an immediate warning sign.
Stormterror's LairPlaces: The ruin of old Mondstadt, the city the storm tyrant Decarabian once ruled, sealed away and long since taken over by Dvalin as his nest. The energy released by the Abyss Mage Diluc hunts down shows Venti how to break the seal, and the group fights through the corrupted lair to reach the dragon. In the battle above it the Traveler cleanses Dvalin of the Abyss Order's poison, ending the Prologue's crisis without killing him.
SumeruPlaces: The nation of wisdom, split between rainforest and desert and governed not by its Archon but by the scholars of the Akademiya. Its god, the Dendro Archon Lesser Lord Kusanali, spent five hundred years imprisoned in the Sanctuary of Surasthana by those same sages, who used the Akasha System to harvest the population's dreams and meant to crown a Fatui-built false god in her place. Freeing her breaks the coup, but the price is that Nahida must erase her own predecessor Rukkhadevata from Irminsul to purge the knowledge poisoning the world tree.
Sumeru AkademiyaPlacesAkademiya: The scholarly body that governs Sumeru in place of its Archon, housed in the Divine Tree above Sumeru City and run by six sages under a Grand Sage. Those sages kept Lesser Lord Kusanali imprisoned for five hundred years, used the Akasha System to harvest their own people's dreams, and — steered by Il Dottore — tried to grow a replacement god out of Scaramouche. Alhaitham's coup on Jnagarbha Day ends the project and puts Grand Sage Azar under arrest.
Sumeru CityPlaces: The City of Wisdom, grown into the Divine Tree and governed outright by the Akademiya rather than by its Archon. Here the Traveler receives their first Akasha Terminal and discovers how openly the scholars despise their own god, and here Nahida later gives the erased puppet Scaramouche his memories back. In the Nod-Krai chapter a monstrous Irminsul tree grown by Dottore towers over it.
Teardrop CrystalItemsTeardrop Crystals: The crystallized tears found near Stormterror, which purify by themselves in the Traveler's pocket and so prove that the Traveler's power can cleanse the Abyss Order's corruption. Purified crystals are what restore the Holy Lyre der Himmel to working order, making them the small object the whole Prologue's rescue of Dvalin depends on.
TenshukakuPlaces: The Raiden Shogun's palace on Narukami Island, seat of the Electro Archon and of the Shogunate that enforces the Vision Hunt Decree. The Traveler defeats the Harbinger Signora in a duel before its throne — and the Shogun executes her on the spot with the Musou no Hitotachi, then turns the same blow on the Traveler.
Teyvat: The world the game is set in — seven elemental nations under Celestia, each with its own Archon. The Traveler is stranded here after arriving from beyond the stars, and the main story is their journey through all seven.
The ChasmChasm: A vast mining scar in southern Liyue that drops down into ancient Khaenri'ahn ruins, including an upside-down Inverted City. Cursed Khaenri'ahns come here to die, and Dainsleif and the Traveler follow the Abyss Order's trail through its depths.
VisionVisions: A gemstone the gods grant to mortals whose ambition is strong enough, letting them wield one of the seven elements. It also marks its bearer as someone Celestia has taken an interest in — which is why the Traveler, who commands every element without one, unsettles everyone who notices.
Vision Hunt Decree: The Raiden Shogun's order to confiscate every Vision in Inazuma and set them into the hand of a statue of herself, on the grounds that only a god should hold eternity. It triggers the civil war that carries the Inazuma chapter, and she repeals it after losing to the Traveler in the Plane of Euthymia.
Watatsumi IslandPlacesWatatsumi: Inazuma's outermost island and the base of the resistance that fights the Vision Hunt Decree under Sangonomiya Kokomi. The Traveler joins it as captain of a special operations unit, and it is here that the war's real cost lands — the anonymous "sponsor" arming the resistance turns out to be the Fatui, and the Delusions they hand out burn the young soldier Teppei to death from the inside.
Witheringthe Withering: A blight spreading out of Irminsul's damaged roots that rots the land and drives creatures mad. In humans it shows up as the disease Eleazar, which Collei suffers from and which sends the Traveler looking for the Dendro Archon in the first place.
