An enslavement empire was led by the Zygerrian MaDall on the planet of Oon, in the Outer Rim Territories in 4 BBY. It included slaves of many different species, including Aqualish, Bith, Duros, humans, Ithorians, Talz, Togruta, Twi'leks, and Wookiees. MaDall also employed a number of Falleen brutes who were tasked with watching the slaves. Although MaDall intended to make her empire an unrivaled slaving operation her side of the Outer Rim, her ambitions were cut short when the Mandalorian freedom fighter Sabine Wren managed to free all of her slaves.
