Oon, a planet characterized by its arid landscape, existed within the Lothal sector situated in the Outer Rim Territories. During 4 BBY, Oon became the site of an enslavement enterprise managed by a Zygerrian known as MaDall. After seeing what happened to those enslaved on Kessel, Sabine Wren, the Mandalorian rebel, made the choice to be captured by MaDall's people and brought to Oon. There, she played a role in freeing the many slaves held by the Zygerrian.
