Canon (fiction)

In fiction, canon is the material accepted as officially part of the story in an individual universe of that story. It is often contrasted with, or used as the basis for, works of fan fiction. The alternative terms mythology, timeline, and continuity are often used, with the former being especially to refer to a richly detailed fictional canon requiring a large degree of suspension of disbelief (e.g. an entire imaginary world and history), while the latter two typically refer to a single arc where all events are directly connected chronologically.

Origin

The use of the word "canon" in reference to a set of texts derives from Biblical canon, the set of books regarded as scripture, as contrasted with non-canonical Apocrypha. The term was first used by analogy in the context of fiction to refer to the Sherlock Holmes stories and novels, written by Sir Arthur Conan Doyle. Ronald Knox used the term in a 1911 essay "Studies in the Literature of Sherlock Holmes" to distinguish Doyle's works from subsequent pastiches by other authors. It has subsequently been applied to many media franchises. Among these are science fiction and fantasy franchises such as Star Trek, Star Wars, Harry Potter, Halo, Fallout, The Elder Scrolls, Mass Effect, BioShock, Doctor Who, Middle-earth, A Song of Ice and Fire, the Narnia series, the The Dark Tower books, and Dinotopia, in which many stories have been told in different media, some of which may contradict or appear to contradict each other.
