Scandinavian Folklore x Mossball

Growing up in Sweden, we had plenty of folklore still being told in books, on TV and in film, mystery like in most places surrounded us.
We have plenty of deep forest which are said to be home to strange creatures like the Troll, Skogrså, Näcken, Nattmara, Elves and much more.
Having these in mind I wanted to also include some of my own nightmares from a fantastic author i read and saw works of as a kid, Astrid Lindgren.
I start with a creature from "Ronja Rövardotter", "Ronia: The Robber's Daughter". There were a few creatures in that series that scared the shit out of me then, one of them being these small creatures of the forest with glowing eyes. they would blend in with the forest and start creeping up on you, there would be hundreds of them. Enjoy.
