There was something found out recently. A descender is someone who came from outside of tayvat AND can change the course of the world.

Ngl I feel like the other twin (The abyss Twin) isn’t rlly our twin, it might be someone else trying to pretend to be them and either our twin is dead or locked up somewhere
