Angosia III was a planet located somewhere in the space of the galaxy's Alpha or Beta Quadrants, the third planet in orbit of the Angosia star system. The homeworld of the Angosian civilization, Angosia III emerged victorious from war with the Tarsians. In the year 2366, the Angosians' bid to join the Federation was jeopardized after Captain Jean-Luc Picard discovered that the native authorities had imprisoned its bio-altered veterans on Lunar V once the war was over.
