This unnamed alien race developed the Berzerker drones found in the second galaxy that was visited by the Destiny expedition. The drones were initially discovered by the Ursini, who accidentally awakened them.
The Ursini had been at war with the drones since then, though they believed the race who initially built them to be long extinct. (SGU: "Deliverance")
