Background[]

Its coordinates from The Federation would place it in treaty boundary quadrant 3, a.k.a. Starfleet Intelligence sector 3, the region containing the Triangle sector. The later-produced sourcebook apparently retconned its position to quadrant 4/sector 4's Twilight Nebula sector for gameplay.
