In Terry Pratchett's Discworld book series, Dunmanifestin is the palace of the gods. It sits atop Cori Celesti, the thin, icy mountain which reaches up into the clouds at the polar Hub (or center) of Discworld.
The Disc gods enjoy playing games with the lives of men in Dunmanifestin - games such as Mad Kings, Star-Crossed Lovers (although the rules for that one have been misplaced), Tempest-Wrecked Mariners, Floods and Droughts, and Mighty Empires. These games are frequently frames for the main plot of the story. The best players are unquestionably Fate and The Lady, the former because he plays by the rules and the latter because she breaks them.
