The Darkstars were formed to patrol space and destroy chaos by the Controllers, an aggressive sect of the Guardians of the Universe, and N.E.M.O., the Network for the Establishment and Maintenance of Order. Ferrin Colos of Zamba, joined the group and was assigned to Earth. After the Darkstars, L.E.G.I.O.N., and the Green Lantern Corps defeated the Triarch—a trinity of evil ancient deities—the three groups agreed on their separate peacekeeping roles in the universe.
