Listening Post X-19 was built shortly after the Rachni Wars, just in case any rachni survived the Annihilation of Suen. The post orbits the mass relay and is still manned and maintained, although today it largely exists as a customs checkpoint for researchers studying the rachni homeworld. Among members of the Council militaries, being assigned to the station is seen as a form of punishment or exile, considering that there have been no signs of sapient life on Suen for over a thousand years.
