About ten years after his birth, the political pressure became too great, and his parents fled Cardassian territory and applied for asylum in the Federation, which was granted.
Though Dalar and his parents were loyal to the Federation, the outbreak of the Klingon-Cardassian War motivated Dalar to apply for entrance to Starfleet Academy. He was admitted shortly before the war ended.
When the Remington's crew was being assembled, Dalar was one of the top candidates recommended to Captain Boswell, who described Dalar as one of the finest young engineers in Starfleet. Dalar requested that he be able to bring a select few members of the engineering staff from the Grant to serve as the core of his staff on the Remington, a request that was granted.
