Fanon

'Fanon' is a term used to refer to 'fan canon' (of which it is a portmanteau). It applies to certain 'facts' that may have been accepted as a truth by a large number of fans, and thus either replaces an established canonical fact in the minds of the fans, or fills a plot-hole. Fanon is occasionally adopted by Expanded Universe authors, and so becomes a form of canon. One example of this form of canon is the mystery of Palpatine's first name. Many fans have adopted 'Cos' as the Emperor's first name, from early drafts of Lucas' work.

Fanon can also take the form of personal beliefs held by individuals. In this instance, an individual may create an expansive backstory, possibly a fan fiction, which they accept as 'true'. These have less standing in the canon than even the fanon mentioned above, and thus are not included in Star Wars Wiki.
