Kinjal

From Memory Alpha, the free Star Trek reference.

The Kinjal are a warp-capable species from the Delta Quadrant. One of the technologies they utilize is a polaron modulator, a rare and advanced module not carried on most ships.

A Kinjal frigate was trapped in the the Void up until 2377 when Bosaal murdered the crew, and stole their polaron modulator. (VOY: "The Void")
