In the World of Greyhawk campaign setting and the default pantheon of deities for the Dungeons & Dragons role-playing game, Olidammara is the god of Music, Revels, Wine, Rogues, Humor, and Tricks. He is often called the Laughing Rogue. He was once transformed into the shape of a small carapaced animal and imprisoned by the mad archmage, Zagyg, but somehow managed to escape.
