Vostigye

From Memory Alpha, the free Star Trek reference

The Vostigye are a spacefaring civilization in the Delta Quadrant. The USS Voyager was due to rendezvous with a Vostigye science station in 2373, but when it arrived it found the station destroyed by astral eddies. (VOY: "Real Life")

The Vostigye were never actually seen in the episode.
