Sigilverse

The Sigilverse, also known as the CrossGen Universe, is a fictional shared universe which served as a setting for most titles published by CrossGen 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). Recognizing 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. That way, characters from different series wouldn't bump into each other on a regular basis (as often happens in other shared universes). Still, there were connections. Some of them were obvious. Others could only be found through careful observation.
