Star Spawn, Hulk

The hulk is the largest of the known star spawn. Though ogre-like in stature, the hulk's glistening translucent skin reveals a muscled form devoid of an ogre's fat. Pale and seemingly lidless eyes glare balefully from a face distorted by too many teeth and too little nose. Hulks are seldom encountered without a commanding seer nearby. A hulk appears to have little will of its own, other than to protect its master.
