this is a sub-rule(?) for the "No Fanon info for canon characters" rule.

Basically, you can't make fan-siblings for canon characters, unless the OC will only exist in your fanon/AU/whatever you call your fanon. Others can also ask for permission to use the fan-sibling of the canon character to their fanon.
