As the story begins, the Alfred Pennyworth of Earth-3 narrates a summary not just in the Trinity War but events since the start of the
Justice League series. While the JL was battling Darkseid, Alfred-3 escaped his world through the weakened barriers, accompanied by Atom. And while the JL was occuppied fighting normal threats, Alfred-3 was working to bring his master to this earth from Earth-3. The three JLs, however, are busy fighting over Pandora's box, thanks to the evil leaking out of it. They battle each other in a superhero verison of the old schoolyard game "kill the guy with the ball", until they finally stop as they realize that the box is affecting everyone else mentally but Superman is being affected physically. Firestorm concludes that there is Kryptonite inside him, and Atom admits that she put it there, inside his brain -- because she is not with the JL, but secretly with the people of Earth-3. Cyborg's robot parts betray him at this point, and tear themselves away from him to become "Grid," a walking virus. In the confusion, Alfred-3 grabs the box, which he reveals is from Earth-3, the "birthplace of evil," and the box acts as a portal. He uses it to gate his allies, the "Crime Syndicate" (an evil anti-Justice League from Earth-3) to our world. Thus the "Trinity War" (Trinity for "Earth 3") ends and the Forever Evil story begins.
