Oskara was a native of the planet Ryloth. When her sister, Makara, was captured by Aqualish thugs to work in the Ryll spice mines she offered her services to the gang leader as an "experienced bounty hunter." Her first job went well and she was mentored by Gyax, a veteran hunter. Oskara continued to work for the spice mine gang to keep her sister safe.
The spice gang loaned her out to Teemo the Hutt on Tatooine and although Teemo paid her well she learned that Teemo was planning on seizing the Ryll spice mine. Fearing for her sister's safety she partnered with the Wookiee gladiator Lowhhrick and the Human pilot Pash and sent a warning to her compatriots back on Ryloth.
