Missa, identified as female, worked as a lady-in-waiting for the noblewoman Lady Kalena. When the Galactic Civil War was ongoing, Kalena and Missa were passengers on the corvette named Indupar Nova. In the Ec Pand system, Rebel privateers boarded their vessel, prompting Kalena and Missa to exchange roles, hoping to shield Kalena. Nevertheless, Captain Urias Xhaxin, who commanded the privateers, recognized their ruse and commanded that both Kalena and Missa be kept comfortably on his ship, the Free Lance.
