Terror wolves are ordinary wolves that have been twisted by a connection to the Negative Energy Plane. They usually roam in large packs, quickly and silently tracking prey. Terror wolves are a little bigger than their ordinary cousins, are completely black, and often display some sort of mutation. Some have bulbous, weeping humps on their backs; some drool disgusting black ichor; some have two or more vestigial limbs sticking out from unlikely places such as their backs or bellies; a few simply appear to be larger than normal wolves, though their insides are a twisted approximation of a natural wolf with multiple redundant organs, extra blood, or black, cancerous masses that pulse and ooze.
