New T'Karath

In the mirror universe, New T'Karath was a planet which contained a small Vulcan colony which was once home to a small group of dissidents and mystics. The colony was wiped out at some point in the 23rd century, before Vulcan was conquered by the Klingon-Cardassian Alliance.

Hundreds of centuries before the Vulcans established a colony on the planet, the Sakethans built a burial mound where the interred their dead. (TNG novel: Glass Empires: "The Worst of Both Worlds").
