You've stumbled on something weird. You're cursed to switch worlds each time you sleep. When you fall asleep in normal Teyvat you wake up in a mirror world of Teyvat where everything is pretty much opposites. The Archons are evil. The Abyss is good. Good characters are bad. Bad characters are good.... worst part the mirror verse wants to find a way to keep you there. Will you be able to fix it before they do?
