Setting:The Editors
The Editors Setting is a setting that considers all works of media ever created as its own world, or subset of worlds inside The Meta, a corner of infinity that connects on a deep level to humanity's imagination.
Introduction
On a level of reality just below our own, the Crossover began. A thousand walls between fiction and the Metaworld tore open, releasing the hungry forces of Sue from their cannibalized homes. Metaworld itself- connection between Fiction and Reality, and the result of seven billion human's perception of Reality, was nearly rent apart.
In the aftermath, with millions dead and cities flattened, the Rifts existed still. The group that had managed the feat of slaying the SUEs stepped forward to defend these gates between Meta and Fiction. They knew that the only way to restore stability was to keep to the Canon, as thousands of Meta inhabitants disappeared into the worlds of Fiction, intent on their own agendas.
The name of these guardians?
The Transpace Guard.
There are millions of millions of Canons out there. From video games, to books, to movies, to movies, traditional games, and more. The goal of the Transpace Guard is to ensure that nobody fucks with the story, and that Canon is preserved, so that the Metaverse remains stable, and no great castastrophe happens again.
Even now, valiant heroes fight to restore stability, from countless bad fanfictions, disastrous crossovers, hostile entities in the Meta, and author-self-inserts known as S.U.E.s.
