This page in a nutshell: Wikipedia articles should describe fiction and fictional elements from the perspective of the real world, not from the perspective of the fiction itself. Jump to conclusions for a more detailed summary of this guideline's contents.
Wikipedia contains numerous articles on fiction-related subjects, fictional worlds, and elements from them.
When an article is created, the subject's real-world notability should be established according to the general notability guideline by including independent reliable secondary sources — this will also ensure that there is enough source material for the article to be comprehensive and factually accurate.
Next, if the subject warrants inclusion in Wikipedia, editors should consider what to write about a subject, and how to best present that information. Because these questions are complementary, they should not be interpreted in isolation from one another, and editors should address both these questions simultaneously in order to create a well-written article.
Please note that this page is a guideline, not policy, and it should be approached with common sense and the occasional exception. However, following the basic notions laid out in this guideline is generally a good way to improve articles on fictional topics.
Articles about fiction, like all Wikipedia articles, should adhere to the real world as their primary frame of reference. The approach is to describe the subject matter from the perspective of the real world, in which the work of fiction and its publication are embedded. It necessitates the use of both primary and secondary information.
Exemplary aspects of real-world perspective include:
See below for a list of exemplary articles which employ a consistent real-world perspective. However, please note that real-world perspective is not an "optional" quality criterion but a general, basic requirement for all articles.
An in-universe perspective describes the narrative from the perspective of characters within the fictional universe, treating it as if it were real and ignoring real-world context and sourced analysis. The threshold of what constitutes in-universe writing is making any effort to re-create or uphold the illusion of the original fiction by omitting real-world info.
Many fan wikis and fan websites (see below) take this approach, but it should not be used for Wikipedia articles. An in-universe perspective is inaccurate and misleading, inviting unverifiable original research by relying on primary source. Most importantly, in-universe perspective defies community consensus as to what we do not want Wikipedia to be or become.

Problems associated with an in-universe perspective include:
For example, if a fictional TV detective loses a partner in the line of duty, taking an in-universe perspective will obscure whether this occurred in the backstory, the pilot or the main series. If the partner died in the pilot, but is the subject of little-known prequel novels, then an in-universe perspective may describe the partner in excessive detail. If later episodes have events which suggest the dead partner never existed, this is impossible to describe from an in-universe perspective, and editors will have to try to explain away such continuity errors themselves, leading to original research and inaccuracy.
Where the above section discusses the principal perspective from which an article is written and makes the distinction between real-world perspective versus "in-universe" perspective, this section discusses the incorporation of information. Please see also the related policy on the use of primary, secondary, and tertiary sources.
