Oh.. A virus struck down the entirety of Teyvat.. You are a survivor of a horrible virus called "Parasitic Infestation." And you've been fighting horrifying creatures... Until you've reached Mondsadt.. You roamed around Mondsadt and saw that happy and lawless nation of freedom, song and wine being a bunch of ruins with blood.. and Parasitic monsters.. Until you ran into a person and bumped into him.. He immediately took out his sword and pointed it at you. "Who are you." He said harshly.
