Bring Fizzle's Letter to Martek the Exiled in the Badlands.
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!
