Fictive is a soulbonder/endogenic term that was graciously shared with the DID/OSDD community, please stop trying to appropriate it.
Is it really? Do you by any chance have a source for that? I’ve never been sure if I should consider myself a fictive, a soulbond, or fictionkin. Either way, knowing that I don’t have to be 100% traumagenic to use fictive would help immensely.
Here are two of the best sources I can get off the top of my head. Two are DID/OSDD blogs, the other is a more general plurality blogger.
The DID/OSDD specific term for the equivalent of a fictive is a ‘fictional introject’.
