Canon (fiction)

• 1. Defining Official Continuity

  ›

  The Royal Book of Oz appeared in 1921, a year after original creator L. Frank Baum died. Ruth Plumly Thompson wrote the entire book under contract with publisher Reilly & Lee. This volume stands as an official part of the Oz series because the original publisher approved it. Canon refers to the body of works that take place within a specific fictional world and are widely considered authoritative. These stories usually come from the original author or developer who created the setting. Works outside this circle often become fan fiction or derivative projects lacking official status.

• 2. Authority And Disputes

  ›

  Copyright holders frequently declare themselves the final authority on what counts as canonical material. Star Wars serves as a prime example where corporate decisions override previous approvals by the franchise's original creator. George Lucas established a tiered system during his tenure that placed live-action films at the top of the hierarchy. He also included The Clone Wars television series and its debut film within this highest tier. Any contradiction between these upper tiers and lower-tier Expanded Universe material meant the newer or higher-tier version always won. Lucasfilm creative executive Leland Chee tracked continuity across all these levels before Disney acquired the franchise. After the 25th of April 2014, Disney reclassified almost all pre-existing Expanded Universe content as non-canonical Legends. A new timeline emerged under the oversight of the Lucasfilm Story Group.

  The Star Trek website defines canon strictly as events occurring within live-action episodes and movies. Star Trek: The Animated Series exists in a gray area of canonicity that has never been fully resolved. Tie-in novels, comic books, and video games are explicitly excluded from the main Star Trek canon despite occasionally influencing later television plots. Russell T Davies avoided making pronouncements about canonicity for Doctor Who while he wrote the series. He stated he does not think about the concept when creating the show or its spin-offs. The Simpsons uses Treehouse of Horror episodes as examples of non-canonical material. These Halloween specials feature stories that take place outside the normal continuity of the weekly series. Productions by Walt Disney Animation Studios remain the only canonical stories under the Disney brand name.

  ›

  Treehouse of Horror episodes present fictional scenarios that do not affect the regular timeline of The Simpsons. These Halloween-themed specials allow characters to experience events impossible within standard continuity rules. Anime adaptations often include filler episodes with original stories that exist outside the source manga's canon. Such extra episodes provide entertainment without altering the core narrative established by the original author. In the Star Wars universe, the Legends designation removed thousands of pages of Expanded Universe content from official history. This decision created two separate timelines where one side contains all post-2014 narratives and the other holds pre-Disney material. Disneytoon Studios productions serve as continuity for films but are ignored by the main Disney brand focus on theatrical animation.

• 5. Posthumous Authorship

  ›

  Fan fiction never holds official canonical status within any fictional universe. Certain ideas gain influence or wide acceptance among fan communities who label them as fanon. This term combines fan and canon to describe community-driven interpretations that feel true to the source material. Plotlines may be reinvented repeatedly until they take on the weight of fan-produced canon. A few persuasive writers can establish personal interpretations that become standard within an individual fandom. The Field Bazaar story was rediscovered and reprinted by A. G. Macdonell in 1934. Its canonical status remains debated because it came from a different publisher than Baum's original works. Copyright laws shifted over time so that authors now hold rights instead of publishers alone.
