- "They will be more than instrumental in the building of my own slave empire—one that will match any other this side of the Outer Rim."
- ―MaDall, about a new batch of slaves
A slave empire led by the Zygerrian MaDall was active on the planet of Oon, in the Outer Rim Territories around five years before the Battle of Yavin. It counted slaves from many different species, including Aqualish, Bith, Duros, Humans, Ithorians, Talz, Togruta, Twi'leks, and Wookiee. MaDall also employed a number of Falleen brutes who were tasked with watching the slaves. Although MaDall intended to make her empire an unrivalled slaving operation her side of the Outer Rim, her dreams were cut short when the Mandalorian freedom fighter Sabine Wren managed to free all her slaves.
