Back, maybe

Speaking of domains, how about mundane underground stuff of history backgrounds? Eg, Decarabian/frosty era in Mondstadt, or areas cursed by ancient gods that now fled to the dark sea?

"atypical" monsters: imbued/strengthened/weakened by leyline abnormalities (eg a hilichurl tribe imbued with electro, hilichurl x something else tribes, etc etc? Could make for some messed up domains ngl)

Natlan rewrite might be good

Angsty jean x diluc slowburn except it genuinely reflects on their character and current relationship

hear me out, what if i wrote the Snezhnaya arc-
