Genshin Impact might be adding at some point a new playable character called Collei – Who’s this character and where is she from?
Collei is a character from the Genshin Impact manga.
Furthermore, every playable Genshin Impact character either has a Vision or has special circumstances that let them use Elemental Power, like being an Archon.
Collei first appears in chapter 2 of the Genshin Impact manga.
