Coldtooth of the Giant Molerat race, in The Thundering Steppes.
Spawned from the experiments of a mad Erudite named Adrial Sunbreeze, this freak of nature roams the highlands of the Thundering Steppes with impunity. Fiercely territorial, most adventurers have found it wise to steer clear of this freakish lab trial gone awry, although the molerat's natural propensity to hoard treasue whets the appetites of many an overzealous adventurer.
Coldtooth's sheer size and strength are enough to discourage most aspiring attackers. If forced to defend its territory, it has been known to let out a cold blast of air that both injures and stuns those around it.
