Fandom Keeper

undefined:

A fandom keeper is a type of archivist and a headmate whose role is specifically to keep track of introjects and other knowledge about them. They may log what sources their introjects have, how many or which introjects lie within that source, how close an introject is to said source, whether a headmate has/wants to integrate from said source, why a headmate would want to integrate from their source, etc.

Fandom keepers are known to often have hyperfixation keeper traits and can be either brainmade or introjected.
