Martek the Exiled

I'm developing a new engine that'll make the car go so fast! Fast enough to fly, I know it! I just need to make pistons that can handle very very heavy stress. All my trials have failed because I can't make pistons hard enough! But there is someone who might know how. His name is Martek the Exiled. He is a great smith and knows more about metal than anyone. Take him this letter, I know he can help! But he's far far away -- in Azeroth, in the Badlands, in a camp, with a goblin! Find him!
