The landscape of the Soul Cairn is barren and dry, with only dead trees and bushes scattered throughout the realm, as well as plant-like growths known as Soul Husks. They are often tricked, and many become trapped as harvested souls. Souls are sent to the Soul Cairn by necromancers who wish to summon these undead, but in order to do so they must travel to the realm in person to finalize the deal with the Ideal Masters. The Soul Cairn is also home to powerful undead beings, which are highly sought after by necromancers. It is believed that the Soul Cairn exists so that the Ideal Masters can collect souls and feed on them some hypotheses even suggest they use the souls as a form of currency to an even higher power. The Ideal Masters are enigmatic entities that lord over the Soul Cairn, controlling every aspect of its being. It is a place devoid of faunal life-the only beings that exist there are souls, undead and the rulers of the realm, the Ideal Masters. When a soul is trapped in a Black Soul Gem and its energy used to power an enchantment, the remnant-the soul itself-is sent to the Soul Cairn. It can be accessed via a portal in Castle Volkihar during, and after, the quest ' Chasing Echoes.
It is a plane of Oblivion inhabited by souls and undead.
