Vintaak system
The Vintaak system was a planetary system which possessed a single gas giant with several moons. In the mirror universe, this system was located deep in Tholian space.

A starship from the future of the prime universe was being held inside a moon of the system's gas giant. In 2155 this was discovered by Commander . After successfully staging a mutiny against Captain Forrest, Archer commandeered and forced the Terran battle cruiser  to the Vintaak system in order to retrieve the captured starship, identified as the . Though Forrest eventually regained command of Enterprise, Archer had locked the helm controls on course for Vintaak. Forrest's attempts to change Enterprises course ultimately proved futile. 

When an away team under Archer's command beamed aboard the Defiant, Enterprise was discovered and captured in a Tholian web. In the subsequent Battle of Vintaak, some of the Enterprises crew was able to abandon ship in escape pods, but the ship itself was destroyed with Forrest still on board. Archer captured the Defiant, damaged the drydock it was held in and took the Defiant to Earth. ()
