The Sigilverse, also known as the CrossGen Universe, is a fictional shared universe which served as a setting for most titles published by Cross Gen Comics. Except for El Cazador, Kiss Kiss Bang Bang, and a handful of flashbacks, all CrossGen Universe titles are set in the future (the 900th century to be precise). Recognising that tightly interconnected shared universes such as the Marvel Universe and the DC Universe tended to confuse and alienate new readers, the creators of the CrossGen Universe set most titles on separate planets.
