Genshin Impact‘s Enkanomiya hides quite a few secrets, which includes this duology of World Quests in Hyperion’s Dirge, and the Phaethons’ Syrtos. Completing Hyperion’s Dirge is required to complete Phaethons’ Syrtos.
While you’re at it, why not see if you can complete:
STARTING THE QUEST
Before you begin, ensure that you have at least one each of the key sigils.
Make your way to the Dainichi Mikoshi and light these torches after defeating some Ruin Guards. Aberaku here will request you find some offerings.
TEMPLE INQUIRY
Make Aberaku appear by unlocking the five key sigils at the Evernight Temple arena. You need to defeat 2 Rockfond Rifthound Whelps and 1 Rockfond Rifthound in 60 seconds.
Successfully clearing the trial gets you Offerings of the Temple.
SERPENT’S HEART INQUIRY
Make Aberaku appear by unlocking the five key sigils at the Serpent’s Heart arena. You need to defeat 1 Pyro Abyss Mage, 1 Hydro Abyss Mage and 1 Electro Abyss Mage in 60 seconds.
Successfully clearing the trial gets you Offerings of the Serpent’s Heart.
NARROW INQUIRY
Make Aberaku appear by unlocking the five key sigils at the Serpent’s Heart arena. You need to defeat 3 Bathysmal Vishaps in 30 seconds.
Successfully clearing the trial gets you Offerings of the Narrows.
HYPERION’S DIRGE
Return to Aberaku and place the offerings in the pedestals behind the spirit. You’ve likely done the trials before realizing the spirit was actually here. Take the orb up to the top.
Touching the platform will get you the Light and Dark, Dusk and Dawn achievement. You’ll also receive the Divine Bridle.
FOLLOWING UP
From the southern waypoint of the Evernight Temple, you need to find two Seelies and follow them during Evernight. They will bring down the barrier that blocks you from speaking to a new spirit, Clymene.
You’ll be asked to find the seven royal tombs and offer a Sango Pearl to each. They will all be marked on your map.
Return to Clymene, who will take you to the Soul Guide’s Locus. Simply place the Divine Bridle as prompted.
That concludes the Hyperion’s Dirge and Phaethons’ Syrtos duology.
