Daval Prestor II was the "second" Lord Prestor seen, after Daval Prestor the First, and was located in Stormwind City during the Beta test. However, at some point, he was removed and replaced by Lady Katrana Prestor — the human form of Deathwing's daughter, Onyxia, who took the name Prestor in homage to her father. If Daval Prestor II was intended to be the return of Deathwing, a relative of Deathwing, or even another black dragon altogether is unknown. This Prestor might have been the Humanoid disguise for Nefarian before he took the identity of Lord Victor Nefarius
