Ajuur the Hutt is a NPC (Non Player Character) in the Taris Upper City Cantina, and the starting point for SWQS quests. If you wish to start questing, you can get a copy of SWQS outside the Cantina. You must wear your SWQS HUD before speaking with Ajuur in order to get quest dialog.
He is a low ranked Hutt, no major crime boss but he has high ambitions. He is continually frustrated by his lack of progress in his goals, and is eager to recruit new assistants.
