In 4,400 BBY, Freedon Nadd conquered the planet and established a dark side theocracy. These cultists were known as Naddists. Naddist tyrants included Warb Null and King Ommin. The Naddists sent Iziz's criminal element (opponents of the Naddists) out into the wilderness without any protection from the animals. These outcasts soon learned to defend themselves, and eventually formed a second civilization, the Beast Riders. Relations between the two groups were hostile, and they remained at war with each other for many years. The Beast Wars lasted from 4,350 BBY to 4,000 BBY, with the final battles serving as the opening salvos of the Great Sith War.
