Vestiges are created when a mortal creature has its soul replaced with a Daedric vestige. The resulting Daedra forms an imitation of the mortal's original body from chaotic creatia. New forms of Daedra are known to be created in this manner. For example, the first Daedric Titan was the Vestige of Boziikkodstrun, a dragon. The most well-understood Vestiges are the Soul Shriven, imperfect Vestiges used as slaves by Molag Bal. Although usually members of the mortal races, Soul Shriven of lesser creatures also seemingly exist.[nb 1] Haskill, the Chamberlain of Sheogorath, is the Vestige of a mortal who previously mantled the Prince following a Greymarch.
The prophecies of the Elder Scrolls speak of a specific "Vestige", the hero known as the Vestige. This Vestige, a Soul Shriven who had been re-attuned to Anuic magic, was foretold to end Molag Bal's attempted Planemeld in 2E 582.
