An engineer assigned to active duty aboard the U.S.S. Westchester, Daniel Morgan was a promising young officer with a potentially bright future in Starfleet Operations. However, when the Westchester encountered the Borg in the mid 23rd century, this future was irrevocably altered. With his fellow crewmates quickly assimilated into the Borg Collective, Morgan was the last to undergo this procedure. With a fateful last-minute intervention from a Starfleet rescue fleet, the assimilation of Morgan was interrupted and he was returned to the care of the Federation. With both the memories and scars of the incident now a part of him for the rest of his life, Morgan uses his brief experience as part of the Collective in order to combat the Borg threat.
