Template:Ratings The Procyon System (pronounced /'proʊsɪən/) is a planetary system situated five days slipspace travel from the Epsilon Indi System. Arcadia, a UNSC colony world, which was invaded by the Covenant in 2531, is orbiting the system.[1]. The eventual fate of the planet and its star system are unknown.
