I am learning a bit more about Greek Christmas traditions, and I just bumped into something pretty spooky - the kalikantzaros, which are Christmas goblins. What really strikes me as that they aren't cutesy Christmas goblins. They appear to be pretty mean! Does anyone know more about them? They are a part of folklore not only in Greece apparently, but also in Serbia, Bulgaria, etc. I would love for you guys to share what you know about them.
