Editive

Not to be confused with fantive, a headmate who embodies an entire or partial sourceundefined:

An editive is a headmate who is sourced from fanmade content for fictional works, with no connections with the original work other then the fanmade content, such as headcanons, AUs, fan edits, spoilers, etc.

A example of a editive could be if a member is sourced for a popular piece of media, even though the body has never interacted with it other than through fanmade works.
