Early life before the Intrepid[]

His augmentation has been kept a secret from both family and whose to whom Ari works with. Ari also has the distinction of starting in the Enlisted ranks before becoming an officer.

Starleet and the Augment issue[]

Because of the controversy with the Augments of the 1990s, Ari's true nature has been kept secret from most of Starfleet. There are only a handful of people who knows of Ari's true nature. Those who know are some of the Starfleet brass as well as Captain Serek. Ari chooses carefully to whom to share his secret with. Those who do know keep his secret and Starfleet turns a blind eye because of Ari's exemplary service record.

Family in Starfleet[]

Ari has a sister, Commander Jennifer Enfield, a Warp Physicist at Starfleet Headquarters and a cousin, Captain Alexander Enfield. Commanding officer of the USS Bellatrix.
