Faerun elves, and most elves from FRPGs, are based on AD&D elves which have Tolkien as their ancestor. That's why they are not furry, tiny, grotesque or overtly faerie folk, and why they are (usually) magically adept and (usually) good swordsmen and archers. The Tolkien depiction has influenced the depiction of FRPG elves from the beginning.
