VSS ShiKahr

The VSS ShirKahr was a Vulcan starship of an alternate timeline in service during the mid-23rd century. The alternate timeline in which the ShirKahr existed was the result of Romulan interference in the timeline.

The ShirKahr was an alternate version of the USS Enterprise (NCC-1701), and a number of crew members from the Enterprise of the original timeline served on board the ShirKahr. This including Spock - who was the ship's embittered Captain, Doctor Leonard McCoy, and Montgomery Scott. James T. Kirk also served on the ShirKahr, and was a disgraced Ensign whose promising career had been sidelined when he was found guilty of a murder during his time at the Academy. In this timeline, Christopher Pike had served as a first officer of the ShirKahr under Spock for a number of years before becoming one of the first humans to be given his own command.

By the mid 23rd century, the Romulan interference in the time line had begun to cause the universe to collapse in upon itself, with a number of highly ranked officers going insane in the process. Captain Spock and Ensign Kirk traveled back in time and were successfully able to prevent the interference from occurring, preventing the time line from occurring and restoring history to its original shape.
