I mean the impression I had for like a decade was essentially this. Then a guy sent me links on how to be his specific type of fantasy creature. It was sergel or sergal iirc. It had some really weird backstory and lore to the species detailing how they were warlords or something and I was really weirded out. It was very much like how some kids I went to school with would loose it if you told them that they weren't whatever comic or movie character they were hyperfixated on, only more socially awkward and adults doing it.
Anyway I feel like that's as close as you can get without reading out someones entire backstory novel.
