longer be the future of the DC Universe. Later, during the Infinite Crisis storyarc, it is retroactively established that Superboy-Prime is responsible for the creation of Hypertime when he fractures the timeline from the pocket dimension he was trapped in. Reaction The Kingdom received some criticism at its time of publication: Originally intended to be simply a prequel bridging the gap between the mainstream DC Universe and that portrayed in Kingdom Come, Ross left the project and Mark Waid revised his intentions into what finally saw print. In a Wizard magazine special, Ross also criticized such things as having the birth of Superman and Wonder Woman's child be a major world affair (Ross thought they would keep such a thing secret to give their child a normal life) and the number of characters Ross had intended to have been killed in the first series that are alive here (such as Zatara, Hawkman, and Kid Flash). The Kingdom was also criticized by some for its poor artwork, but was praised by others for the concept of Hypertime. Hypertime was an in-story metaphor for reader response and canonicity, variously described as a river and tributaries of continuity, a geometric construct, and in various other deliberately mutable ways.
