Rasa worked as a hitman for an Alderaanian crime family his whole adult life. He was off-planet on a job when the Death Star blew up his homeworld. With nothing to go back to, he joined the Rebellion to make the Empire pay for what they'd done

Revenge. Rasa never took much interest in politics. Figured whoever was in charge, a man with his skills would be able to make a living. After his homeworld was destroyed, Rasa vowed to kill as many Imperials as he could, not caring if he died in the process. He spent weeks stalking the edges of an Imperial base, killing dozens of stormtroopers and officers. Just as the net was closing in, and he was preparing to sell his life as dearly as possible, Mr M. appeared, offering him a way to get away from his pursuers, and a chance to play a part in doing real damage to the empire

20 - Criminal. Rasa was used to working with impunity, because local law enforcement were in the pocket of his employer, but after doing several high-profile jobs off-world, he had started to attract Imperial attention. Although most of the people who knew his identity died on Alderaan, it's only a matter of time until his past catches up with him.

Tall and whippet-lean, Rasa holds speaks little, and holds himself unusually still, content to wait, and watch, picking his moment to spring into action
