In 2152, Sub-Commander 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, led by Commander Thy'lek Shran, requested that Captain Jonathan Archer mediate over their argument, Muroc was sent to escort Ambassador Soval while he boarded Enterprise NX-01. Muroc was also sent to go with Archer to talk, but Archer dismissed this, as it would send the wrong message. He took T'Pol with him instead.
As Archer then convinced Soval to go to the planetoid himself to talk to Shran, Muroc monitored from his ship and, when Soval seemed to be in danger, he planned a rescue mission. He later attempted to engage the Andorian battle cruisers that arrived to assist Shran when Commander Tucker maneuvered the Enterprise in between. Muroc decided not to further engage and wait for more information from the surface. Soon, he was hailed and informed that Soval had made it with Archer and T'Pol to Shran's command post.
