Galactic 4th Edition
During the Century Long War, the two sides of the conflict conducted experiments in creating super soldiers. One of these failed experiments was the breeding of Humans and Katirin (Dwarves) by the Arkonians (Dragonborn), creating the Nutirin (nōō-tēr-ĭn) race. The creation was far too unruly for the Arkonians to control properly in combat situations. They were turned into a slave race. Most Nutirin are now free, save for those still in the Arkhosian Remnant.
