It's Simple, We Kill the Sandy Claws

From itch.io: A Christmas-themed one-page dungeon written for four, level one peasants in Knave. However, this dungeon should be compatible with most old-school style games. The hamlet of Ricabouth is ruled by Greta Fernsby, a 12-year-old girl with psychic powers and a bad temper. She is hosting a mandatory Christmas Eve party at the Fernsby manor house, during which she intends to capture Santa Claus and display him, alive, in a suspended cage until he dies of exposure. It is up to the PCs to stop her. Or join her. Or rob everybody. Anything goes.
