Arkology was a massive orbital habitat that served as the site of the climactic season four finale battle against the Magog World Ship. The self-sustained colony came to house one of the Paradine, a being capable of stopping the Abyss so the Magog, the self-proclaimed harbingers of the Spirit of the Abyss, set out to destroy it. Dylan Hunt learned he was one of the Paradines on Arkology.
