Praaelon Di was a Human Rebel-allied arms dealer. He provided weapons to both sides of an uprising on a mining colony on Weldii III, causing the facility's administrator, Lenc, to put a bounty on his head. With a number of Rebel agents and battle droids at his side, Di clashed with a pirate fleet and a group of bounty hunters, led by Boushh, before traveling to Weldii III and taking the fight to Lenc there.
