The Southern Wastes were an area on the Ubese homeworld, Uba IV. Presumably, they were wastelands formed after the planet was bombarded during the bombardment of the Uba system.
Circa 3 ABY, it was home to several Ubese clans, including Clan-Vorsazg, a clan led by War-Master Savax. These clans, possibly with Hutt assistance, manned a flotilla of capital ships to attack the yrak pootzck Ubese of Ubertica. They managed to lay waste to several Ubertican cities before being destroyed by Imperial forces.
