Bluish rough scaly skin, dark thick hair, dark curving horns on his head, piercing yellow eyes, and a large mouth lined with thick sharp tusks.  This bestial creature seems to be some form of troll, once rather feral but having been warped my the influence of some dark magic for an unknown purpose.  Whatever the case, this once feral beast now has a more cunning intelligence to help it reach it's goals, whatever those may be.
