In an alternate timeline, the Vulcan High Command vessel Muroc was a starship in service to the Vulcan Protectorate in the 23rd century. The Muroc was named for the "hero of Paan Mokar". Its design resembled an advanced version of the Suurok-class, and employed coleopteric warp drive like its prime universe predecessor. The Muroc and its version of Vulcan existed in the home timeline of Miri's World, a universe where Earth was devoid of most Human life and the Federation never existed.
