Fictional universe: definition, structure, history and uses
A fictional universe is a deliberately constructed setting for one or more works of fiction. This article explains what they are, how they are built, and why they matter across media.
Overview
A fictional universe is a deliberately created setting that houses characters, events and rules used across one or more works of fiction. It can be limited to a single tale or extend across novels, films, games and other media. A single concise definition is hard to give because every creative project makes choices about scope, continuity and perspective: some universes are tightly consistent, while others are modular collections of related stories. For general discussion of the concept see the basic definition.

Core characteristics
Most fictional universes are built from a combination of setting elements and governing principles. Setting elements include geography, cities, cultures, timelines and major institutions; these are often first introduced in books and later expanded in adaptations. The medium affects presentation: role‑playing games emphasize mechanics and playable locales (RPGs), while film and television focus on visual continuity.
- Rules and physics: many universes alter physical laws or add systems such as alternate physics, technology for space travel or frameworks for magic.
- Scope: can range from a single city to an entire galaxy (galaxies) or multiverse.
- Temporal placement: stories may be set in the past, present or future.
History and development
The practice of creating recurring fictional settings has roots in folklore and serial literature, where storytellers reused locations and archetypes. In modern publishing and entertainment the term grew as creators intentionally connected separate works into consistent continuities. Writers and designers—often identified simply as the author or worldbuilder—expand a universe by adding locations, species, technologies and institutions, and by establishing shared events that other creators may reference.
Uses, examples and importance
Fictional universes allow creators to reuse and deepen ideas, making sequels, spin‑offs and adaptations feasible while preserving internal logic. They are especially prominent in science fiction and fantasy, where speculative elements such as extra‑solar planets or faster‑than‑light space concepts are central, but they appear in mysteries, romances and historical dramas as well. Examples range from small, character‑driven settings to sprawling mythologies used across media.
Distinctions and notable concepts
Key distinctions include the difference between a single fictional work's setting and a shared universe used by multiple creators; the latter requires management of canon and continuity. Transmedia universes let different media explore complementary facets—games may detail day‑to‑day life, novels may explain history, and films may dramatize major events. A fictional universe functions as both a creative constraint and a resource: constraints guide consistency, while the shared background deepens meaning for audiences who follow multiple entries.

Term History
The term was first defined by comics historian Don Markstein in a 1970 article in "CAPA-alpha," one of the first Amateur Press Associations.
Connection to the real world
Fictional worlds do not have to differ significantly from reality. In principle, each plot location of fiction corresponds to an independent reality. However, especially in science fiction and fantasy, supernatural elements are often woven in. Fantasy is often set in a mythologized past. Fairy tales, sagas and myths also fall into this category, as do modern adaptations of them (The Mists of Avalon by Marion Zimmer Bradley or the Winter Solstice cycle by Susan Cooper). In addition, there are equally worlds that are reached by a transition in a reality that mimics reality. A classic example of this is Alice in Wonderland.
However, many fantasy worlds are independent. The forerunner of fantasy literature is Middle-earth, penned by J. R. R. Tolkien, on which many later fantasy worlds and role-playing games have been based. Tolkien also wrote on the process of inventing a fantasy world, world-building, which he called subcreation.
