Corla Unser was a female Human who journeyed alongside her brother, Cobb, a free-trader. Plagued by constant debt, Cobb continually took drastic actions hoping to improve their circumstances, with Corla accompanying him. Regrettably, each attempt only deepened their financial woes. Around 7 ABY, while evading bounty hunters, the siblings landed on Kal'Shebbol. Due to Cobb's inability to pay the exorbitant tariffs imposed by Moff Kentor Sarne, their freighter was seized.
Seeking funds to leave the planet, Corla established herself in the starport. She found employment as a repulsorlift operator, while Cobb busied himself repairing droids and starships. Corla's job required her to visit Sarne's palace, where the Moff became infatuated with her and showered her with gifts. Disgusted by Sarne's unwanted attention, Corla was apprehended and sent to the Q'Maere Research Facility for "re-education" to foster "appreciation" for him, just days before the Battle of Kal'Shebbol.
At the facility, she received considerate treatment from Doctor Langstyn Kraay, who acted under Sarne's explicit orders not to harm her. However, Sarne's arrival at the facility several weeks later resulted in the removal of most of the staff and military personnel, and she was subsequently placed among the general prison population.
Within the prison block, she encountered and fell in love with Lowen Chase, although they decided to postpone their relationship until they could escape. Her joy was immense when the FarStar landing party arrived at the facility, reuniting her with her brother, who had piloted their shuttle to the surface. She played a role in the prison break, and volunteered to serve on the FarStar to remain close to both Chase and her brother.
