Muroc was a Vulcan officer in the Vulcan High Command in the 22nd century.

In 2152, Subcommander Muroc was assigned to a D'Kyr-type cruiser that was sent to settle a dispute on Paan Mokar/Weytahn, a planetoid claimed by both the Andorians and the Vulcans. When the Andorians requested that Captain Jonathan Archer mediate over their argument, Muroc was sent to escort Ambassador Soval while he boarded Enterprise. Later when a new agreement was beginning, he toasted with Andorian ale to it with Shran, Archer, and Soval. (ENT: "Cease Fire")
