The Devils

The Devils were seen in The StoryTeller episode, The Soldier and Death. They were known to haunt a building and play cards there every night, undefeated, until the soldier challenged them to a game of cards and beat them. After the night was over and the defeated devils attempted to eat the soldier for beating them, the soldier forced them into his sack and beat them, eventually releasing them but forcing one to serve the soldier, eventually releasing him from slavery in exchange for a glass that can help him see death.
