Silumm was abandoned sometime in the First Era, but was briefly occupied during the rule of Direnni Hegemony. During the Interregnum in the Second Era the ruin is being explored by the Aldmeri Dominion forces, secretly expanding into the Daggerfall Covenant territory. The Dominion was expecting to find something useful in the ruins or at the very least establish an outpost to be used against the enemy. Dominions best armsmaster, Sincano, is part of the expedition.
Some werewolves can be found using Silumm as a hideout, killing the Dominion explorers.
