shareduniverse

A shared universe is a fictional setting in which multiple authors create stories that occur within the same world and can reference, influence, or intersect with one another. It relies on a common premise, recurring locations, and a cohesive canon that enables crossovers and continuity across different works.

In officially published media, a shared universe is often established through coordinated worldbuilding and governance. An editorial team or licensing body may maintain canonical timelines, style guides, and decision rights to preserve consistency across comics, novels, films, television, and games. This governance helps writers align on character histories, events, and the rules of the setting. In fan communities, shared universes emerge organically through collaborative writing, wikis, and fan-made crossovers, though these are typically non-commercial and not legally binding.

Notable examples commonly cited for their scope include the Marvel Universe and the DC Universe, which span comics and various media with interconnected characters and events. Other long-running franchises, such as Star Trek and Star Wars, have developed expansive shared settings created by numerous authors and producers. Shared universes can also exist at smaller scales, such as a publisher’s multi-author slate within a single fictional city or nation.

Common advantages include rich storytelling potential, cross-pollination of ideas, and a built-in audience. Challenges involve maintaining continuity, avoiding contradictions, coordinating contributions, and navigating licensing or permissions for cross-media adaptations.
