Dungeon World: Leviathan
In the underworld, people may get the attention of Death. If they are talented, if they are lucky, then maybe he will have a purpose for them. If he does, then he’ll have a mission for them.
Death cannot directly affect the world without the intervention of those he has saved, and if they don’t obey him then there might be terrible, terrible consequences.
Death is also not a player of games. Not chess, and not wordplay.
