Sera'Yah the Wicked is a skilled necromancer. Once a member of the Kirin Tor, Sera'Yah has been studying the necromancy which Kel'Thuzad once got banished for it. She was contacted by the Acolytes in time, as she joined the Cult of the Damned. She did continue her studies into the Scholomance. The necromancer is attempted to find the phylactery of Kel'Thuzad and to revive the mighty lich, or to find him to know about his current status, to know if the leader of the Damned is alive. With the Dark Lady controlling her, her goal wasn't possible, and after some time, she dropped it.
