J.R.R practically invented the concept of "elf".(aka legolas, arwen and elrond)The norse legends and stuff all seemed like they were more like the fay right?
Okay, now if modern day thinks elves are all tall & sexy, how the hell did the freaky midget things in Santa's workshop spring up?
In some legends, "dark" elves have body parts of animals. As in they look completely human, but might have a hoof for a hand, or a crows foot. Or maybe a dogs ear.
