Wheels & Walls

From the introduction: It is the unimaginably distant year of 3019. In the last millennium, everything has changed. Everything except for the two Immutable Societies: Wheels and Walls. You are Society members, followers of the ancient disciplines, but you no longer subscribe to the religious doctrine that chained you. You are fleeing across the desert. For the first time in centuries, a handful of Wheels and Walls control their own destiny.
