While Morrowind contains many quests and storylines, the central plot revolves around The Tribunal, a triumvirate of god-like beings ruling over Morrowind, and their struggle against a former ally, the deity Dagoth Ur and his Sixth House – a cult of followers stretching out from Red Mountain, the volcanic center of Vvardenfell, the island on which the game is set. Dagoth Ur has used the Heart of Lorkhan, an artifact of great power, to make himself immortal and now seeks to drive the Imperial Legion occupiers from Morrowind using his network of spies, as well as Akulakhan, an enormous mechanical golem powered by the Heart of Lorkhan.
