Tenarus Cluster

From Memory Alpha, the free Star Trek reference

The Tenarus Cluster is a region of space in the Delta Quadrant dominated by the Kazon-Nistrim. A course for the USS Voyager plotted by the Kazon Tierna in late 2372 prudently avoided the Tenarus Cluster, although he was sending Voyager into a trap anyway. (VOY: "Basics, Part I")
