This page in a nutshell: Wikipedia articles about fictional subjects should be attributable, have suitable detail and scope, and be written from the perspective of the real world, not from the perspective of the fiction itself.
Wikipedia contains numerous articles on fictional worlds and elements from them. For articles dealing with fictional subjects, characters, objects, events or locations, significance outside the narrative itself should be established and discussed, together with its process of authorship. Once a topic's notability has been established, the approach to writing about these subjects is the most important consideration to make. This essay describes some guidelines towards writing a proper article on fiction.
