Early in the year 2354, the Hansens left Heronius II aboard the Raven, along with their five-year-old daughter, Annika. (VOY short story: "A Ribbon for Rosie") Eight months into their journey, they found a Borg cube, and the Raven was pulled into that ship's transwarp conduit into the Delta Quadrant. The Raven continued to study of the Borg until 2356, when an ion storm damaged the vessel's shields, and they were detected by the Borg. The Hansens were assimilated, and the Raven crashed on a moon in B'omar space in the Agrat-Mot Nebula.(ST reference: Star Charts)
