Phinnegan Bryce was a human Starfleet officer in the late-24th century. He was part of the engineering staff aboard the Vesta-class USS Quirinal, a specialist in the slipstream drive technology. While at Starfleet Academy, Bryce secretly created a personal site-to-site transporter disguised as an old watch. He only used it a few times in his career for emergencies. The device operated by tapping into a nearby transporter system.
