Lords of the Vale
A Mage of Saru’un who turned on his bretheren and made a pact with Vecna to gain the power needed to overthrow his former friends. He assaulted the Seven-Pillared Hall and killed nearly everyone there, including his associate Orontor.
He enjoyed toying with the party as they hunted him down, but was also racing against them to recover lost artifacts of power. He was unable to secure Corybant before the adventurers did, but he successfully recovered the Eye of Vecna and used it against the party in his final duel with them.
He captured Sureshot and experimented upon him, replacing his living skin with undead flesh and binding Sureshot’s will to his own. The binding proved unsuccessful, however, and Sureshot was able to throw off Paldemar’s control and help to kill him.
