Beneath the argent glow of Teyvat's eternal moon, Hiisi Island emerges as a realm where ancient mysteries slumber within crystalline vaults and labyrinthine caves. Here, the Evermoon Seals—Nod-Krai artifacts pulsing with celestial energy—beckon adventurers into a dance of light and shadow. These obsidian-like rings, coveted keys to forgotten treasures, nestle exclusively within Precious Chests scattered across thunder-swept shores and subterranean kingdoms. Three such seals await discovery: two woven into the tapestry of grand quests, while the third lies concealed in the island's uncharted folds, each pulsating with the promise of revelation.

The Evermoon Seals: Celestial Keys to Hiisi's Heart

Forged from starlight and silence, these artifacts function as spectral counterparts to Obsidian Rings, their power resonating with moon-blessed vaults. To claim them is to embark on a pilgrimage through Genshin Impact's most enigmatic landscapes:

• The First Seal: Emerges during For a Green Island, where thunder meets tide

• The Second Seal: Revealed through The Mirrors, the Maze, and the Tsar, a subterranean odyssey

• The Third Seal: Waits in solitude within a random Precious Chest, a solitary gift from the island

🌿 For a Green Island: Thunderclap's Verdant Symphony

🦀 The Mirrors, the Maze, and the Tsar: Crab King's Subterranean Waltz

Commencing south of Light-Bathed Platform, travelers descend into earth's memory where rock crabs scuttle through gloom:

Beyond lies a Precious Chest, prelude to the Tsar's pacification. Moonlanes carry travelers deeper, where Fragments thrown through Moon Mirrors unstick rocks from the Crab King's carapace. Rewards bloom in darkness—two Precious Chests and one Luxurious Chest—their glow painting the cavern in liquid silver.

💎 Hiisi's Hidden Caches: Seals Beyond Quests

The third Evermoon Seal dwells beyond narrative paths, guarded by the island's silent sentinels:

• Tideseal Stone Vigil: Northwest of Lost Mooncourt Domain, defeat spectral guardians to unveil a Precious Chest

• Northern Shore Enigmas: Solve Moon Mirror puzzles by manipulating blocks with Kuuhvenki Energy—push, pull, align

Three additional chests await conquerors who challenge Hiisi's fiercest foes, their contents glimmering with lunar promise.

🌙 The Treasure Vault: Frostmoon Enclave's Celestial Gift

Where ice and eternity converge on Frostmoon Enclave's eastern cliffs, the Treasure Vault rests—a reliquary for gathered seals. Travelers teleport to the enclave's heart, then soar eastward toward a hovering Lunoculus. Behind its radiant form, the vault materializes, its doors hungry for the triad of Evermoon Seals. Inserting them unleashes a symphony of light, rewarding persistence with artifacts whispering of forgotten eras.
