Smuggling, piracy, loansharking, blackmail... during last 46 years even slavery... the organized criminals of the Cularin system take advantage of the relative insulation of the system with a boldness unseen ouside the Outer Rim.
[Riboga]] the Hutt started building his organization over 80 standard years ago and fought the Smugglers' Confederation until when he absorbed it in his network as if it was a corporate merger.

Nirama more recently bought off the whole organization and changed some policy, being against slavery.
