Heh heh, with all the races they're running here, it's no surprise that a few mishaps happen along the way. If you look around the Shimmering Flats then you'll see evidence of past crashes -- scraps of rocket car parts are littered everywhere! And those parts are worth money to the gnomes and goblins. They're always looking for more contraptions to slap onto their cars. So go out and get me parts. Bring me a heap and I'll pay you well.
