Akulakhan, also called the Second Numidium, is the name of the machine god built by Dagoth Ur under Red Mountain. Using the divine influence of the Heart of Lorkhan to power Akulakhan, he planned to use it to drive all outlanders out of Morrowind, cast down the Tribunal, spread Corprus, and eventually take over all Tamriel. Dagoth Ur also planned to establish a theocracy based on the worship of Akulakhan with his Ash Vampire brothers serving as the god priests of Akulakhan. But, in 3E 427, the Nerevarine arrived in Vvardenfell, recovered Kagrenac's Tools—the Dwemer artifacts Wraithguard, Sunder, and Keening—and led an assault against Dagoth Ur's stronghold. Using the power of the tools, the Nerevarine was able to destroy the tonal enchantments on the Heart, killing Dagoth Ur and destroying Akulakhan.
