The Crozo (/ˈkroʊˌ.zoʊ/) are an ancient race of stellar wanderers, migrating around the galaxy. Being members of the Ancients, the Crozo oppose intervening in the matters of younger races for fear of corrupting them, much like Mnemosyne.
However, due to the increasing threat of the Chaos Legions, many are beginning to see that interference may be more necessary than previously thought, and that the survival of the galaxy as a whole is more important than the sustained cultures of thousands of smaller races; while the various younger races may become corrupt by being uplifted or helped by such powerful older races, they likely could not destroy the universe. However, the Chaos Legions are extradimensional and keep increasing their numbers with the likelihood of eventually consuming everything if they are not stopped. Where the universe may be decimated but live on if thousand(s) of immature races become corrupted by power, the Diimons will leave nothing untouched by their corruption and as a whole the universe would eventually become just another Diimon Headquarters.
