Lembatta Cluster

From Memory Alpha, the free Star Trek reference

The Lembatta Cluster is a region of space located near the border between the United Federation of Planets and the Klingon Empire.

In 2373, the USS Farragut was destroyed by Klingon forces near the Lembatta Cluster, while en route to offer relief to Ajilon Prime. (DS9: "Nor the Battle to the Strong")

The novel Articles of the Federation mentions a planet called Lembatta Prime, which author Keith R.A. DeCandido states is near the Lembatta Cluster.
