The information here comes from a post made by the official account on Hoyolab on 08 May 2026.

I heard the Interastral Peace Corporation dug through basically all the information on this batch of Supplicants, except for me… As for the reason, apparently my “identity is a mystery” and my “origins are hard to trace,” or something like that. Sigh, turns out being too mysterious is a hassle in itself.

Forget it, I'll just write up my own profile. Just in case Phantasmoon Games ever goes under… maybe I can still send it out to apply for jobs or something?

Character Info

Name: Evanescia
Age: ?

Record:
Former Elixir Seeker “Swordsinger”
Current Planarcadia Panarch Elwood (aka Ambrosial Arbor Spirit)

Identity: “Phantasmoon Games” Arbitrator and Supplicant

Past Experience
In her early years, her kin had come to call her the “Swordsinger.” She was super strong~. Totally matchless, defeating everyone in her path… well, except for that blazing Phoenix of the Xianzhou.
Later, she embarked on a tireless quest to seek the elixir for her people, and was ultimately granted eternal life, transforming into a branch of the Ambrosial Arbor in the garden of the Abundance.
After that, she was secretly planted in Planarcadia by some busybody to serve as the arbitrator fro the “Phantasmoon Games.”

Hmm, did I fill this out a little too honenstly?

If you don't believe me, save your interrogation for Graphia~ o(￣へ￣o#)
