Novus Ordo Sectorum (A new order of the ages is created.)
A group of female Witches of the planet Dathomir, its members turned to the dark side of the Force. Nightsisters enslaved Imperial guards at a Dathomir prison and attempted to flee the planet to gain power over the galaxy some four years after the Battle of Endor. They were vanquished by Luke Skywalker, Leia Organa, and Han Solo, but fifteen years later a new order arose. These Nightsisters were younger, stronger, and allied with Imperial forces seeking to regain control of the galaxy. But, alas, those were vanquished once again by opposing forces, dying on foreign planets such as Kashyyyk. Now, the new breed that have remained behind have grown stronger and more organized and are even now seeking what assistance they could acquire, or steal, to become a power in the galaxy.
