- "For a slave, Orvax is the living hell of the galaxy. There is no worse place that I know of."
Orvax IV was a slave trade planet in the Outer Rim Territories. Slaves were stored in dungeons here before being sold off to slave owners. The slave traders lived in the upper levels of the cities. Members of the T'surr species worked as security staff.
Following the Battle of Half-Axe Pass, the Empire deported captured Nosaurian women and children there. Dass Jennir and the crew of the Uhumele attempted to rescue Bomo Greenbark's family, only to find that his wife Mesa had been killed and his daughter Resa sold to Dezono Qua on Esseles (thus sealing her fate, as Qua regularly bought a child slave to eat).
