Gavin Moon was a male Human who was employed by the Bennett Corporation as a starship captain. As of 2377, he commanded the Otwa Tandewan, along with first mate, Adjani.

That year, he transported a shipment of upgraded sensor and communications equipment supplied by the Bennett Corporation to Federation Outpost 32. Also aboard for this trip were Patrice Bennett and her personal assistant, Gris Giernad. (CoE eBook: The Art of the Comeback)

Moon's title of "captain" is apparently due only to his position as a ship commander, as opposed to being a rank.
