Trinity #1 (1993)

It's a sprawling cosmic saga as the stars of GREEN LANTERN, L.E.G.I.O.N. '93 and THE DARKSTARS come together in one of the greatest space adventures ever: DC UNIVERSE: TRINITY, a crossover in 8 parts that decides, once and for all, who has jurisdiction over the spaceways. TRINITY is the story of the Triarch, a trio of ancient deities who, a billion years ago, attempted to remake the universe. Now they're returned to finish the job, forcing the Green Lantern Corps, L.E.G.I.O.N. and the Darkstars into a cataclysmic war with seemingly omnipotent beings.
