Admiral Sharfer was a high-ranking officer in the Maquis by late 2373.

In that year, Sharfer was one of many top level personnel that were assigned to the transport Orb of Peace to be evacuated from the planet Galion to Bajor after negotiations with the Cardassian Union failed. Following a brief argument about the terms of Ro Laren's command of the Orb, Sharfer backed Ro and stated that anyone who did question her orders would be thrown in the brig. In return for his support, Ro appointed Sharfer as the Orb's first officer. (TNG - The Dominion War novel: Behind Enemy Lines)
