Sentinel 3 - A recently built deep space look-out post that was designed to act as an early warning for alien invasion. Only 8 years after being positioned close to the galactic rim a brief alarm signal was received before all communication was lost. Upon investigation, all personnel had vanished with no sign of struggle. The station has therefore been placed off limits to all but the Liandri Federation who now use the danger of Avenger as a popular arena for deathmatch competition.
