- "I've always thought that tie in novels were professionally produced fanfic—and if they're not, there's something wrong."
- ―Karen Miller
The term "fanon" is used to refer to fan-made fiction. Fan fiction (also spelled fanfiction and often abbreviated to fanfic) is a story written by fans that takes place in an established fictional universe, such as Star Wars. Such fiction is unrecognized by Lucasfilm and is therefore non-canon.
Fanon made official canon
Fanon is occasionally adopted by Expanded Universe authors. One instance of this was the 501st Legion, a clone trooper unit that is named after a real charity organization. The fanon—or simply elements of it like the name in that case—thereby becomes canonical.
The What's The Story? competition invited members of the Hyperspace fan club to submit fan-written backstories of selected characters, the best of which were accepted as their official backstories.
