Bring 10 Indurium Flakes to Martek the Exiled in the Badlands.
I'm not out here just to stay away from people. There is a wealth of metal in the Badlands, <name>, if you have the guts to get it.
The metal's called indurium and as luck would have it, it is rumored to possess high resistance to heat and stress. It might work for Fizzle's car.
But let's make sure. Get me samples of indurium and I'll test its properties.
True indurium ore lies deep in Uldaman, but the Stonevault troggs of the Badlands sometimes have flakes of it on them. Bring me those flakes.
