The Mountain of Doom, a geographical feature of natural origin, was a mountain situated on the forest moon that circled the gas giant known as Endor.
This mountain, found on Endor's forest moon, was dubbed the Mountain of Doom by the indigenous Ewok inhabitants. They held it in dread because of the Frost Giants that dwelled within. The mountain's surface was marked by numerous caves, which descended far into its core and contained crystalline structures. The Frost Giant King had his throne room in one of these caves, from which he governed. The fire plant, a resource feared by the Frost Giants but prized by the Ewoks, thrived on the mountain's rocky terrain. Ewok lore claimed that no Ewok had ever journeyed to the mountain and lived to recount the experience. Teebo and Wicket Wystri Warrick, two Ewoks, made the trek to the mountain and lived through it, disproving the myth and obtaining the uncommon fire plant.
