Yeah trolls are an interesting bit of folklore simply because there is so much variation from lore to lore. There are the trolls that lived under the bridge in the children's fable, who were never really described but had to be fairly human-like. There are the trolls of Tolkein, who are dumb, brutish giants which will turn to stone if exposed to sunlight. In other folklore, trolls are benign woodland creatures, industrious but covetous of precious metals. The Dungeons & Dragons troll is unlike any other, a huge, monstrous beast with sharp claws and fangs, able to regenerate entire body parts like a starfish. And then there are the little troll dolls, really what the fuck is up with them, especially little old ladies bringing them to bing halls?
