Cryptid
This is a creature that some people theorize exists, but for which no scientific evidence exists. Think Bigfoot or the Loch Ness Monster.
Why I Looked It Up
It came up in Once Upon a Tome in reference to a category of humans that were just odd and difficult to figure out.
It was a bitterly cold afternoon when I met my first bookshop cryptid, and I remember it well.
