Rithgar was a former pirate and the master of the Kothlis shadowport.
He lived in private quarters within the shadowport, where the loot from his past pirating days was held. He kept a blaster carbine on him at all times, and owned an old Z-95 Headhunter starfighter.
In 3 ABY, Rithgar had invited a few smugglers to his chambers within the Kothlis shadowport, including To'iir, Liadden, and Tru'eb Cholakk. The friendly meeting was broken up early when, unexpectedly, a Super-class Star Destroyer approached the shadowport.
