Starfleet service careerEdit
As a cadet, Mason, along with first-year cadet John Mayhill, was on a tour of the Cochrane Research Facility on Sirius IV when the reactor exploded. Twenty people, including Mayhill, were trapped in the radioactive core, and Mason watched them die of radiation poisoning from the shielded observation room. Even years afterwards, Mason would occasionally have nightmares about that day.
Mason started his career as an ensign at Starfleet Security, where he met Captain Matthew Harris. Harris was the liaison officer to the newly created Starfleet Intelligence and sent Reed on several covert operations on behalf of both divisions. At first, he found this sort of life exiting, eventually he realized that some of the missions Harris sent him on weren't authorized by Starfleet. When Harris came under scrutiny by his superiors he left Starfleet, leaving Mason with the impression that their affiliation is over.
He was reassigned to Starbase 11 as a security officer and was promoted to the rank of Lieutenant Junior Grade and had a great assignment there.
