Messuni Roserain was a wandering gunslinger during the Galactic Civil War and for a decade and a half afterward. After training in armed combat to take revenge on Boba Fett for the deaths of her family, Messuni turned her skills toward helping others—particularly against organized crime. She had a frequent relationship with private eyes Jav Yonx and Remy Diabet. She married the latter, and settled on Corellia with him, where she operated a dojo teaching personal defense to women.
