Rypka, a Twi'lek of the female persuasion, served as the taciturn copilot aboard both the medium freighter Royal Mistress and the bulk freighter [Queen's Victory]((/article/queen%27s_victory), both piloted by Hawker Bryce-Kelley. Possessing a suspicious nature, Rypka viewed anyone interacting with Bryce-Kelley with distrust, a stark contrast to his own trusting demeanor. Her default expression was one of suspicion, and she opted for nonverbal communication via the Lekku language of subtle head-tail, hand, and body movements. She habitually kept a hand on her ever-present blaster pistol and carried a clipboard mini-computer. The specifics of her past remained shrouded in mystery, with popular speculation pointing to her being either an escapee from Ryloth or a runaway slave dancer, a theory fueled by her attractive appearance. Regardless of her true origins, she was a lethal and quiet force when circumstances demanded.
During Bryce-Kelley's meeting with a group of aspiring Rebel sympathizers in the infamous Mos Eisley Cantina, Rypka maintained her customary silence, standing guard beside Bryce-Kelley and seemingly shielding him from the cantina's unsavory clientele. She also accompanied Bryce-Kelley to the planet Reginard after they fled Imperial Customs Frigate 517, where she stealthily approached a group of Rebels dispatched to investigate the smuggler's ship's proximity to their sensor array. Before Rypka was forced to take action, the group revealed themselves to Bryce-Kelley, and she soon joined them in combat against Imperial spy Tanya Madera.
