The Broken Wheel Hills are a region of rugged, rolling grasslands in the southern reaches of the Aban Steppe. They separate the more temperate areas around Tomb Lake from the rest of the steppe.
The southern branch of the Hundred Days Road passes through the Broken Wheel Hills. Though this route is a faster way to the sea than the western branch, it is widely considered to be considerably more dangerous. Not only are the Hills home to numerous drakes, but even after passing through them travelers must avoid the war-chariots of the Xuldorai, aggressive giants of the Aban.
