Durrsk, a crime lord of the Quarren species, operated on Nar Shaddaa. Tyrnia Masak's mother had accumulated a significant unpaid balance with him. Because of this failure to pay, Durrsk chose to abduct her daughter. The girl was then instructed in the art of combat by his fighting master, becoming a highly skilled gladiator. In a moment of uncontrolled anger, Durrsk would eventually kill Masak's mother; at her subsequent gladiatorial contest, Masak responded by eliminating the Quarren along with his Hutt guest.
Subsequently, Masak had a bounty placed on her head by the Quarren's relatives.
