Megzeg Nukklebust

"'Would you believe it? These orcs hired me to help them shore up damaged fortifications and build explosives. What a dream job! It's too bad we're so short on materials, but a clever goblin like myself learns how to make do!'"
 * ~ Megzeg Nukklebust - Thrallmar, Hellfire Peninsula

Megzeg Nukklebust can be found in Thrallmar in Hellfire Peninsula. He has been hired by the Horde to shore up defenses and build explosives and other killing machines. He completes his assigned tasks with great aplomb. . Interestingly, with all the Goblin's receiving a new model in Cataclysm, it seems Megzeg received a model with Death Knight eyes.

These orcs must really be eager to stake their claim in Outland! If I told you how much they were paying for my allegiance, you'd kill me out of jealousy!
