This guide shows how to complete the “Yachimatahime’s Locus”, which is a subquest of the world quest “Erebo’s Secret “ in the Enkanomiya area of Genshin impact 2.4. Erebo’s Secret is available once you’ve defeated the Abyss Lector Fathomless Flames.
How to Start the World Quest – Erebo’s Secret
Head to Serpent’s Heart in Enkanomiya – and make sure Evernight is active. You will find the shade of Eboshi, near the northwestern fast travel point of Serpent’s Heart.
Interact with the shade and accept the challenge. This will spawn three islands along the edges of Enkanomiya’s map as marked on the map below. You will also be assigned three new subquests.
Using the Ghostfish and reaching the new islands
These three islands along the edges of the map cannot be reached directly and can only be accessed by using the Ghostfish portal. These Ghostfish portals can be found at the pools of water as marked on the map below. Travel to the nearest Teleport Waypoint and head to the pool.
Jump from a height to the Ghostfish portal located in the middle of the pool to activate your glide. Here you have to control your stay within the radius of the Ghostfish’s effect and this will slowly float you upward. Eventually, you’ll enter a portal that takes you to its corresponding floating island. There are three different Ghostfish portals to take you to three different floating islands.
Head to The Evernight Temple area and go to the marked location of the Ghostfish portal pool of Yachimatahime’s Locus. Jump from a height to the Ghostfish portal to start the glide. You will enter a portal that takes you to Yachimatahime’s Locus.
Talk to the afterimage in front of the seal
Once you reached Yachimatahime’s Locus, speak with the shadow (Eki) near the seal. Once the conversation gets over, the seal will vanish and you can enter inside.
Release all the Flames of the High Gate (0/4)
Inside, you’ll need to interact with all four Flames of the High Gate. Use the portal to reach higher ground.
Defeat the floating Specters and then interact with the cauldron.
The flames themselves won’t appear on your minimap, so you have to check their relative location based on the visions. I have marked the location and image of all four flames below.
After collecting all four Flames of the High Gate, head to the next tower and talk to the shade. This will complete the Yachimatahime’s Trial quest in Genshin Impact.
