Incandescent Ode of Resurrection

Arriving in Natlan, the Traveler and Paimon discover a nation unlike any other: its Pyro Archon is a human, its Statue of The Seven refuses to grant the Traveler Pyro, and yet the local energy called Phlogiston answers their touch. They befriend Kachina, a timid young warrior of the Children of Echoes whom the Wayob chose as an Ancient Name bearer — and who has just been abandoned by her team on the eve of the Pilgrimage of the Return of the Sacred Flame.

Through Kachina they meet the wavechaser Mualani, the Saurian hunter Kinich, and his loudmouthed companion Ajaw. The Pilgrimage, they learn, is no mere tournament: its victors earn the honor of fighting the Abyss in the Night Warden Wars, protected by the Ode of Resurrection that revives fallen Ancient Name bearers through the Sacred Flame. As outlanders may not compete, Mualani partners with Kachina instead.

In the Stadium of the Sacred Flame, Kachina and Mualani fight through the team stage, and Kachina defeats her doubters in the duels — until the bracket pits her against Mualani herself. Refusing to hold back, Mualani pushes Kachina to prove her strength, and Kachina prevails, earning her place in the coming Night Warden War. The act closes as the Pyro Archon Mavuika personally welcomes the Traveler, revealing she has been expecting them, and the chosen warriors march against the Abyss.

The Night Warden War is won, but at a terrible price: Kachina falls in battle, and when Mavuika enters the Sacred Flame to resurrect her, she returns alone — Kachina's soul and Ancient Name are missing. Suspecting the Abyss has undermined the very rules that protect Natlan's heroes, Mavuika suspends the Pilgrimage and reveals another crisis: the Contending Fire that fuels the Sacred Flame is running out, forcing her to sacrifice her own Archon power to keep it burning.

Worse follows. Capitano, First of the Fatui Harbingers, storms the stadium, accuses Mavuika of failing a five-hundred-year-old oath, and duels her to a standstill before a masked accomplice from the Masters of the Night-Wind spirits him away. Meanwhile the Traveler, Mualani, and the sharpshooter Chasca seek out the shaman Vichama, whose harrowing Spiritspeaker ritual recovers Kachina's Ancient Name from the Night Kingdom.

Descending into the Night Kingdom — the soul-realm the Lord of the Night wove from Natlan's shattered Ley Lines — the rescue party fights through Abyssal corruption to reach Kachina, who has survived in hiding after something tried to devour her soul. They bring her home, confirming the Abyss now gnaws at the Wayob themselves, while Mavuika orders Kinich to ask the shaman Citlali about Capitano's mysterious rescuer.

Mavuika sets the smith Xilonen an impossible task: forging an Ancient Name for an outlander, something the Night Kingdom has never recorded. To find a way, they need Citlali — the centuries-old, youthful-looking shaman of the Masters of the Night-Wind — who agrees to petition the slumbering Lord of the Night if the Traveler helps clear the name of Ororon, the young tribesman who saved Capitano and has since vanished into Fatui hands.

Tracking Ororon by night, the Traveler is pulled into the Night Kingdom, where Capitano himself requests a parley. Freed from the Fatui camp, Ororon secretly arranges the meeting: Capitano, a Khaenri'ahn survivor of the cataclysm, believes Mavuika's plan to defeat the Abyss will fail and hints at a hidden backup plan whose price she refuses to pay. Citlali, furious at Ororon's collusion, is talked down, and confesses the tribe once used the boy's incomplete soul in a failed ritual.

Mavuika confirms the truth: the Lord of the Night could rebuild Natlan's Ley Lines at the cost of erasing the Night Kingdom — its souls, history, and culture — and she will not allow it. The act ends as the Abyss launches a coordinated, nationwide assault, scattering the heroes to their tribes' defense while the Traveler resolves to uncover Capitano's true plan.

Raiding the Fatui excavation of the Source Mechanism, Mavuika's strike team confronts Capitano and Ororon — and awakens Yohualtecuhtin, the Lord of the Night, last of the angel-like beings who rebuilt Natlan's Ley Lines as the Night Kingdom. Ororon survives a soul-shattering ordeal and is acknowledged as the fifth hero, receiving the Ancient Name "Bidii." Rather than let the Lord of the Night sacrifice herself, Mavuika forges an unprecedented alliance: the Fatui will fight beside Natlan against the Abyss.

Xilonen and Citlali secretly learn the cost of their own plans — forging the Traveler's Ancient Name should consume the engraver's life, and Mavuika, empowered by the death-god Ronova, is fated to die — yet they obtain the Pilgrim's Chronicle to record the Traveler's deeds. Then the Abyss unleashes a full invasion: tumor-like pylons rain from a black sun, tribes fall, and the land is littered with the dead.

Amid the carnage, Chasca's beloved sister Chuychu dies of Abyssal corruption; her grief awakens the final Ancient Name, completing the six heroes. Empowered by their ritual, Mavuika declares a Night Warden War for all Natlan, destroys the rift — briefly exposing a "false sky" above Teyvat — and repels the invasion, though victory leaves the nation in mourning.

With the black sun routed, Natlan wins a brief respite, and the tribes help one another rebuild. The Traveler and Paimon join Iansan of the Collective of Plenty at the hard-hit Flower-Feather Clan, where survivors of the invasion suffer a rare affliction: three warriors — Atoco, Cochitta, and Ocotlan — have been left trapped in trauma and hallucination by the Abyssal "Reaper," Gosoythoth.

Patient care brings two of them back: Atoco must finally accept the death of his Saurian companion, and Cochitta rediscovers her courage protecting her little brother. But Ocotlan's Abyssal Corrosion Syndrome runs too deep — until Capitano appears with the Draught of Lucidity, a cure developed during the cataclysm by his second-in-command Guthred, a military doctor who tested it on himself and died completing it.

Capitano reveals more of himself than ever before: his flight from Khaenri'ah, his respect for Natlan's defenders, and — removing his mask to show the Traveler his true face — his grudge against Ronova, the Ruler of Death, whose curse torments his people's restless souls. The interlude closes on a hopeful note as the heroes gather at the Stadium of the Sacred Flame: Xilonen can finally begin forging the Traveler's Ancient Name, the last piece needed to end the war.

As Mavuika prepares her final descent into the Night Kingdom, the heroes share a farewell feast, and Xilonen — defying the rule that forging costs the engraver's life — completes the Traveler's Ancient Name: "Tumaini," meaning hope. Testing it draws countless stray souls to the Traveler, and Citlali guides as many as she can into the Night Kingdom, including the fallen shaman Vichama.

Before the assembled nation, Mavuika reveals the Traveler's Ancient Name and carries them into the Night Kingdom's depths. Spirits of the dead — Atea, Vichama, Mallko, Chuychu, even the heroes of five hundred years past — clear the Traveler's path, while Mavuika confronts the Abyssal leviathan Gosoythoth. When the Sacred Flame gutters out in Teyvat, Kachina rallies the people's song, and with the Lord of the Night's blessing of Pyro, Mavuika and the Traveler destroy Gosoythoth for good.

Victory has a price: Ronova demands Mavuika's death for wielding her power. At Ochkanatlan, Capitano intervenes — his cursed, undying body has hoarded the souls of his fallen comrades for centuries. By fusing his existence with the Lord of the Night, he takes Xbalanque's seat, saves both Mavuika and the dying goddess, and grants his people rest, remaining forever as the Night Kingdom's silent guardian. Natlan, at last, is free.

Peace in Natlan is interrupted when the Traveler finds their sibling's Hibernation Chamber key — proof the Abyss Order is nearby — just as the Order launches coordinated attacks on all six tribes. Near the key's resting place they meet Direidyth, a strange young woman searching for a prophesied "Savior": a description that matches not the Traveler, but their sibling. Oddly, she can only perceive certain monsters while holding the Traveler's hand.

Dainsleif arrives, single-handedly mauling the Order's front lines, and identifies Direidyth as a pure-blooded Khaenri'ahn. Together he and the Traveler storm the Order's headquarters in Ochkanatlan, where an Iniquitous Baptist — Dainsleif's own disgraced master, Haden — claims the sibling has used the Loom of Fate to re-weave Khaenri'ah's Ley Lines. Dainsleif executes him hundreds of times over, exposing the boast as bait: the Order sacrificed its army hoping to harvest Dainsleif's memories of the lost nation.

The truth is stranger still. Direidyth and the Traveler are from different points in time, their meeting arranged by Istaroth. The sibling appears at last: the attack was a feint so they could bargain with the Lord of the Night, weaving New Khaenri'ah's Ley Lines into an "Atlas of the New World" — leverage to one day face the Heavenly Principles as an equal. They part, promising to meet again in the new world.
