Nuu'Bari
From Memory Alpha, the free Star Trek reference
The Nuu'Bari are a spacefaring humanoid civilization from the Delta Quadrant. They employ primitive holograms as laborers.
In 2377, a Hirogen vessel commandeered by Iden attacked a Nuu'Bari mining ship to "liberate" the holograms aboard, although the holograms were non-sentient. After he obtained the holograms, Iden destroyed the vessel. (VOY: "Flesh and Blood")
