Festival of Lights · Diwali
The Light Screen revealed Teyvat’s ancient Dragon Clan, its conquest by Phanes, and the cycle that bound the world, forcing the observers to question their own order. The arc ended with Nibelungen transformed by the Abyss and a war between two thrones and two Descenders looming.
Phanes defeated Nibelungen but was left cursed and gravely weakened, so he created Demon Gods bound to protect humanity while he suppressed the Abyss. After a Golden Age, he ordered the Demon Gods to fight for seven seats, and the decree drove Teyvat’s people and rulers into betrayal and slaughter.
The Light Screen follows the Archon War’s betrayals and devastation, then shows Barbatos freeing Mondstadt and Morax building Liyue through contracts, mortal strength, and an alliance with Guizhong. It leaves Gu Yuena wondering whether an equal alliance between humans and Soul Beasts could have prevented the Dragon God War.
The Light Screen recounts how Morax protected Liyue through sacrifice, contracts, and mortal rule, while Gu Yuena and the observers reconsidered the meaning of strength and protection. After Morax’s story ended, the screen began revealing how Raiden Shogun True and Raiden Shogun Ei shared the work of ruling and defending Inazuma.
The Light Screen showed Ei’s pursuit of Eternity, the Traveler’s challenge that restored change to Inazuma, and the Scarlet King’s catastrophe after he unleashed Forbidden Knowledge. It left the observers learning that the Great Compassionate Tree King saved Sumeru by erasing herself from its people’s memories and entrusting it to Naxida.
The Light Screen revealed Elysia and Furina’s sacrifices in Fontaine, then followed Xibalak as he united Natlan’s people and dragons, defeated the corrupted Fire Dragon King, and became the Guardian Fire. The arc left off as Marvica questioned the Fire Gods’ inherited sacrifices and the scene shifted to the time before the catastrophe in Kandria.
Marvica and Capitano defeated the Abyssal Will at the cost of Capitano’s life, while the Light Screen revealed Teyvat’s ancient history and the rise and fall of Nibelungen. The story left the observers confronting Phanes’s rule, Nibelungen’s corruption and revenge, and the betrayals that followed.
The Light Screen revealed Phanes’ betrayals and Khaenri’ah’s rebellion, then showed how Ilmin’s ambition turned Kong into a vessel for the Abyss. Kandria was destroyed by the corruption, and its Sages concluded that Kong had to die to stop it.
The Light Screen revealed how the Five Sages betrayed Dainsleif and how the Heavenly Principles destroyed and sealed Khaenri'ah during the Cataclysm. It then uncovered the Sinners’ powers and ended by turning attention to Vedrfolnir’s prophecy about Surtrochi and the rise of Moon Hunter Rerir.
The Light Screen revealed Surtrochi’s rise from a battle-hungry knight to a universe-spanning predator who consumed gods, worlds, and stars. After Surtrochi effortlessly erased Kailar and his planet, Tang Wulin’s confidence faltered, and the screen ended with Surtrochi facing a fleet before a blue planet.
Surtrochi trained Sikeke into the Witch, while the screen revealed the intertwined tragedies of Kong and Ying and their conflict with the Heavenly Principles. The arc ended with the watchers learning that the universe faced Dark Fate, a destructive force opposed by the Primal Will.
The Light Screen revealed the cosmic forces behind Teyvat’s False Sky, then exposed Honkai and the Herrschers as civilization-ending threats with power beyond the gathered gods. It ended by showing the Finality Herrscher restore a dead planet through time reversal, leaving even the Dragon God unable to match her feat.
The Light Screen revealed how the Herrscher of Finality repeatedly erased civilizations and how the Previous Civilization fought the Honkai, culminating in Mobius’s dangerous experiments to force human evolution. The arc ended as Mobius transformed Cosmos into a monstrous creature and called the result evolution.
The Light Screen revealed the Thirteen Heroes of Chasing Fire and showed Elysia, the first Herrscher, choosing humanity and sacrificing herself to free future Herrschers from Honkai. The Previous Civilization’s final battle ended in annihilation, Huo Yuhao collapsed after hearing the name Kiana, and a new side story began with Kevin at school.
The Light Screen revealed Kevin’s losses, the Kaslana Family’s inherited fight against Honkai, and the Previous Civilization’s failed attempts to survive. It left the observers confronting Kevin’s Holy Mark Plan, which could awaken Stigmata in a few people but turned most test subjects into Undead Soldiers.
Kevin returned from the Sea of Quantum and pursued plans to prepare humanity for Honkai, including turning Mei into the Lightning Law User and using Hare to spread Stigmata. The Light Screen then revealed the Flame-Chasers’ Honkai Will Plan, which ended with Prometheus 17’s sacrifice igniting a point of consciousness within Honkai.
Kevin imprisoned Finality within himself and challenged the next generation to defeat him, while Kiana emerged as humanity’s hoped-for successor. The review then traced the tangled fates of K423, the real Kiana, Siegfried, and Cecilia, before beginning Leanna Brigantia’s story.
Sirin became a six-core Herrscher and brought catastrophe to Earth, while Fu Hua, Siegfried, and Cecilia fought to stop her. Their victory ended with Otto ordering a missile strike that killed Cecilia and Sirin, leaving Siegfried alive and K423’s consciousness awakened by Cecilia’s love.
Otto’s schemes awakened Sirin and led to the destruction of Sky Vault City, while Himeko sacrificed herself to free Kiana from Sirin’s control. Kiana began using the Herrscher’s power to protect others, but after saving the city, she was left exhausted and hunted by Schicksal and World Serpent.
Kiana loses Mei and confronts the Herrscher born from Fu Hua’s memories, then helps Fu Hua return. As the Thousand Herrschers exploit humanity’s despair and trap Kiana in a soul war with Sirin, Benares intervenes on Kiana’s side, revealing the split in Sirin’s soul and leaving Kiana resolved to face her.
