Genshin Impact: Child of the Abyss

(This story has a few contradictions and isn’t an ordinary fanfic. Characters from Genshin Impact appear only occasionally, but the author will do their best to portray them and their storylines faithfully. There should be some angst, though the blade is pretty dull.)

An endless abyss, an ordinary boy, a snowy nation in the Far East, a lost ancient kingdom, mysterious cults, and a continent home to countless factions. What kind of story will the Traveler from beyond the skies witness?
