Fan-created material that can be accepted within the current state of Erfworld canon is termed "fanon".
Conflicts with Canon
As stated in the Guidelines for fan art, The Creators and their appointed representatives on Earth may designate fan material as inappropriate to Erfworld, for any arbitrary reason they see fit. Material that has been declared inappropriate may be deleted without requesting permission. This isncludes, but is not limited to, violations of copyright, trademark infringement, or inappropriate use of the Erfworld characters.
Third party Edits
Please note that under the policies of this Wiki, it is not possible to prevent other contributors from modifying your fan created content. To ensure nothing is done to your content that you do not wish to happen, please ensure you keep a local back-up, and keep "Watch" on your page, so that if it is maliciously modified, you are made aware. This should not be used to restore any content deemed inappropriate by the creators or their representatives.
