Zerx Hydromon

Zerx Hydromon was a hydromancer who had a camp outside of Vol'jin's new base camp in Dustwallow Marsh. He was guarded by Sea Elementals. He had the title of Grand Wizard.

As he was not an objective, his fate is uncertain.

Speculation
He is presumably an independent wizard drawn to the Magistrates Temple and not a member of Admiral Proudmoore's forces. Zerx does not have the Kul Tiran dark green color and will attack the nearby soldiers in Captain Thornby's camp if they get too close.
