A Murloc Sorcerer (that was Named "Murloc High Sorcerer" in Warcraft 3 Demo) was the leading figure of the Underworld Minions, besides Sea Witch, and succeeded in having Thrall and Sen'jin captured — along with many orcs, trolls, and even humans. Though Thrall and most of the prisoners escaped the dungeons, Sen'jin could not be rescued in time and Thrall helplessly watched the witch doctor be viciously cut down by the unknown Murloc Sorcerer. Thrall afterwards dealt with unknown Murloc Sorcerer appropriately; by killing him. Two other murloc sorcerers existed, and fought against Thrall in his final battle against the Underworld Minions.
