Vadam Keep

Vadam keep is the keep of the House of Vadam, the ruling Sangheili clan of the state of Vadam in the Yermo province of Sanghelios. Over three thousand years old, it is a large castle-like fortress built on the lower slopes and base of Kolaar Mountain with warrens running inside the mountain itself, something that has made it well defensible over the ages. During the San'Shyuum-Sangheili War, the state of Vadam was one of the many Sangheili city-states attacked by the Reformist San'Shyuum. However, their keep was too well-defended to be destroyed.

In ancient times, after being overthrown, Ther 'Vadam and his soldiers were imprisoned in the keep. Ther eventually escaped and after recruiting followers from the wilderness, returned and retook the keep. In 2535, shortly after being elected as kaidon of the state of Vadam, Thel 'Vadam was attacked by three assassins sent by Koida 'Vadam, all of whom failed, and were all killed by his own hand without a scratch.

During the Servants of the Abiding Truth's insurrection in early 2553, the Vadam keep became the target of a concentrated attack by the insurgent forces. The intervention of eventually drove back the attackers, although the keep took heavy damage.
