Unspecified Wanderers of the Worlds [can be group or even one on one.]

[TwilightWolf]

I know that this might not get anyone's attention, but I recently got back into Genshin and had a random thought. What if before the twins had gotten separated and wound up in Teyvat, they used to live in the Kingdom of Hyrule and had an older brother figure in Link, who like them had disappeared after facing down a great evil, only to somehow now wind up in Teyvat as well. Together with either Aether or Lumine, set out to find the other twin, and explore this new world.
