Outlaws, nomads, lowlifes. They are named for the fact that most wear roller blades, skates, or wheels of some kind to aid their wandering. They don’t fit in with any other faction, or just don’t hold loyalties. Some have disrupted the ceremony of dance, cheated, or interrupted a competition, but somehow escaped the sentence of Death by Groove. Others are ex-spies who have had their cover blown. Some are just nuisances to society.
