The Arch-Warlock of Yeth'mir. Knows more than a few ways to kill you. And yes, i did make him up randomly.

dosen't rely on weapons or magic specifically, uses both. (Eat that wimpy robe-wearing skyrim wizards! this warlock is a REAL MAN! :P) 
 uses a variety of magic, both elderitch (teleporting, necromancy, etc.)and elemental.(if you dont know what elemental magic is, you are an idiot.)
