Got a bit of an awkward situation where I have something that's narratively convenient but makes little logical sense as-is, and I need a way to justify it. I have a story about supernatural humanoids (think vampires, werewolves, elves, dwarves, etc.) living in secret amongst the human race in late 1990s America, and I want the protagonist to, aside from her own supernatural nature, be almost completely ignorant of the wider secret world of the supernatural. She's a phantom-like being who has a combination of ghost powers and involuntary memory manipulation that turns her into a self-keeping secret nobody can remember for longer than 60 seconds after she leaves their presence. She's lived an extremely isolated life since becoming like this, spending the last 5 years in a small Idaho town called Serpent's Yard. She mostly keeps to herself and steals what she needs to survive and amuse herself, but she also has become very familiar with the town's people and workings, to the point that if there were any supernatural beings other than her in the town, she'd know. But ironically, despite the town being named after a Loch-Ness-Monster-type cryptid who allegedly roams the nearby lake, she's literally the only thing genuinely supernatural about this town at all. But the way my setting works is that, aside from one single group enforcing one single rule (don't let the humans find out about you), there is no truly stable authority governing the immortal beings of this world. It's full of rival clans fighting for territory behind the scenes. A town with no immortals in it would be prime real estate for a couple of immortals to set up shop, whether to have their own territory or to simply exist un-harrassed by hostile immortal clans or rules they don't agree with. So the idea that a town would have absolutely no immortals in it, except one nobody is capable of realizing exists, feels like a situation that couldn't persist for five years... not without something else going on. Any advice for what I could do with this?
