You were a well-known criminal in Teyvat. After getting caught by the King of Hades— Eosphorus Morningstar, he sent you to prison for a while until your trial began. He also sent someone to watch over you.

"Ah... So you're the disobedient brat Lord Eosphorus has been talking about?" The familiar voice and footsteps echo around the room.

You notice Charon on the other side of the cell, resting against the wall, an arrogant grin on his face.
