The framing device of the story involves future versions of
John Constantine and
Rip Hunter travelling to the present day, ostensibly to prevent a catastrophe involving the superheroes of their time. The hook through which the series would connect with other titles is the attempts of the two time travelers to recruit others into their quest to alter the future through warning them of upcoming events. Individual books in the
DC Universe could tie into the crossover or not, as their creators wished, by having Hunter or Constantine show up and warn the stars of the book of some event. The main narrative of the series involves Constantine relating the story of what has happened in the future to his present-day self over drinks in a bar. The series was set in the future where the world is ruled by superheroic dynasties, including the House of Steel (presided over by
Superman and his wife
Wonder Woman) and the House of Thunder (consisting of the
Marvel Family) as well as houses built around the
Teen Titans, the
Justice League, and an alliance of supervillains. The Houses of Steel and Thunder are about to unite through the marriage of
Superboy and Mary Marvel Jr., the daughter of
Captain Marvel and
Mary Marvel, with their combined power potentially threatening the status quo, and several characters attempt to stop it. One group of opponents is a shadowy cabal of non-powered heroes led by
Batman. Another involves an alien alliance of the
Green Lantern Corps, Martians, and
Thanagarians. Constantine's narrative of the future ends with a massive battle between the various factions, resulting in the death of most of the superpowered characters. A side story would show a decaying superhero ghetto where decrepit versions of old heroes live. In the final part of the present time framing device it would be revealed that Hunter and Constantine had traveled back in time not to prevent the future they came from, but to ensure its coming true. The final battle depicted in the book resulted in humanity being freed from the control of superheroes, a prospect that Hunter and Constantine supported. The series would have restored the
DC Multiverse, which had been eliminated in the 1985 mini-series
Crisis on Infinite Earths, but the series would also have been a significantly darker take on DC characters than had previously been published, with many of the future versions of the heroes depicted as murderers, perverts, and tyrants. A central plot element of the series, for example, involves
the Question investigating the bondage-themed murder of someone who turns out to be
Billy Batson. In the end, the wedding between the Houses of Thunder and Steel is attacked by the allied houses and the alien army, killing many heroes including Superman and
Martian Manhunter, who had killed Batson under the guise of a call girl and disguised himself as Captain Marvel. After the alien army appear victorious, Batman's army of non-powered superheroes, aided by Constantine, attack and reveal that Constantine had made a dealer with the armies of the antimatter universe
Qward to invade their own homeworlds and force them away from Earth. As Constantine and Rip Hunter talk, the former realizes that a lot of what came to pass did because of what his future counterpart told him he should do, and after reading a letter from his future self, is angered at being outsmarted. He thus takes revenge, and aims to prevent that future from happening, by turning down talking with a woman whom his future self married. ==Legacy==
