In the Dungeons & Dragons fantasy role-playing game, Gelf Darkhearth is the gnomish deity of entropy and revenge. He was introduced in the Races of Stone supplement book. In many campaign settings, the gnome pantheon of gods consists of the leader Garl Glittergold, as well as Baervan Wildwanderer, Baravar Cloakshadow, Flandal Steelskin, Gaerdal Ironhand, Nebelun, Segojan Earthcaller, and Urdlen (others might be present in specific settings). Gelf Darkhearth, along with The Glutton, Ril Cleverthrush and Sheyanna Flaxenstrand, being introduced in a supplemental book, are not considered canon to the pantheon.
