Estoritive

undefined:

An estoritive, alternatively an estoriject, estortive, or estorject, is an exoject/exotive who comes from a fictional universe, but is not an existing character or an OC. They existed in their source's setting, but were not part of the source's story.

They could be considered a type of fuzztive, and are separate from fictives due to not being an introjected form of an existing character, and from mostives/OCtives and ouroboroi due to being originally formed as a headmate, not an original character.

An estoritive invariably comes with at least one exocanon, or a group of exomemories making up one distinct "life"/continuity, but they may also have more than one.

History
The term comes from Old French estorie, meaning "a history, story, or tale", along with the suffix -tive, for a term applying to outsourced members.
