Ten Dorne was a Sluissi who worked on Admiral Gial Ackbar's Shantipole Project, the development of the A/SF-01 B-wing starfighter with complete access to Verpine shipyard facilities in the Roche asteroid field. Dorne was working on a device known as a shearing plane, which would render tractor beams ineffective. After several close run-ins with Imperial forces, Dorne reconsidered her position with the Alliance and defected to the Empire. The latest reports placed Dorne at the Vosteltig shipyards.
