Teyvat’s players haven’t returned for several years since the story was completed. During that time the characters have all become sentient. Though with the players gone, the NPC’s are no longer alive despite their bodies remaining intact, as though they are unharmed and full of life, just missing a soul. You ended up finding your parents old account, but to your surprise, you get pulled into the game. You have complete access to all codes and look around at the broken down world.
