Zabrak Toil
The Zabrak toil took place in 3923 BBY when Nahier Ahimuri led a charge against the night sister population with the aid of the Zabrak slaves. Nahier freed them with the aid of some other night sister activists and Defenders, then led an attack against the other night sister clans. This resulted in the complete liberation of the Zabrak species, and they were accepted in as night brothers shortly after.
