Attending the bar is an enigmatic figure known as Decim, who also acts as the arbiter. He passes judgment on those who wind up at Quindecim by challenging them to a life-threatening game. These games determine if the patron's soul will reincarnate into a new life, or be sent into the void, never to be seen again.
