Homeworld to an extinct race long thought mythical until clues to its location at coordinate 227-m-359 near the Romulan side of the Neutral Zone were discovered by the late Capt. Donald Varley amid some outpost ruins at another site. It is dead now, its cities destroyed by large-scale aerial attack, but a generator continued within the mountains of its smaller continent until destroyed by Captain Picard to keep it out of Romulan hands in 2365.
