Reego Hinterstar was a space pirate. In 1 ABY he robbed the cargo of Captain Sava Matar's CR90 corvette Null Racket. To get his cargo back, Matar hired a freelance strike team to track down Hinterstar on Corellia and retrieve the cargo.
Behind the scenes
Reego Hinterstar is mentioned by name in the mission "Take Down Hardened Space Pirate", that is offered to players on Corellian mission terminals in Star Wars Galaxies. As all other missions from these terminals, the mission only leads the player to a randomly generated base with a small group of thugs that he needs to kill. Hinterstar doesn't appear in person.
