An empire centered on enslavement was under the control of the Zygerrian MaDall. This empire existed on the planet Oon, situated within the Outer Rim Territories, and its reign occurred in 4 BBY. The enslaved population consisted of numerous species, such as Aqualish, Bith, Duros, humans, Ithorians, Talz, Togruta, Twi'leks, and Wookiees. Falleen brutes were also in MaDall's service, serving as guards over the enslaved. MaDall's aspirations to establish the most dominant slaving enterprise in her region of the Outer Rim were thwarted when Sabine Wren, a Mandalorian freedom fighter, successfully orchestrated the freeing of all enslaved individuals.
