Mutants are the offspring of humans who ventured too closely to the source of Quantum's power (called Prime). As such, they are often called Primespawn. Mutants come in a variety of shapes and sizes and their mutations range from the useful to the patently grotesque. When two mutants pair and have children, their children are always mutants, though they rarely possess the same mutations as their parents. Mutants are reviled in both human and azi cultures and those who choose to stay are often cast out to the fringes, scraping by as criminals or beggars. Those who flee bond together as tribes and wander the wild places of Quantum, avoiding human and azi cities.
Ah. "Primespawn" that have mutated by venturing too close to the center of power in their world. Hmm, I've had a similar idea to that before - it must be something that resonates well in the human mind.
