There are so many out there it isn't funny...

Everyone knows Angels, Demons, Devils, etc...or at least I hope you do. They also know the basic Ghost type spirits...

But how many of you know of the Russian based SnowMaiden?

None? No shock. So share with me your wealth of knowledge upon the obscure spirits, give us brief information such as where they're from...and maybe even a link or two to a site that has some info on them..?
