Murloc Sorcerer

From WoWWiki

The Murloc Sorcerer is one of two heroes of the Murloc forces in the Reign of Chaos demo Campaign made by Blizzard called Exodus of the Horde. It is an intelligence hero that casts Rain of Fire and shoots fire balls. It is the only Murloc that can talk.

The Murloc high Sorcerer was the leading figure of the Underworld Minions and succeeded to have Thrall and Sen'jin captured along with many orcs and trolls. 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 Murloc high Sorcerer. Thrall afterwards dealt with the Murloc high Sorcerer appropriately; by killing him. Several other Murloc Sorcerers existed, and fought against Thrall in his final battle against the Murlocs.
