In the Dungeons and Dragons role-playing games there exists the Dwelf, which is a hybrid between Dwarf and Elf.
The Hobbit movie franchise shows a romance between the dwarf Kili and the elf Tauriel.
I wasn't particularly impressed by that addition by Mr. Jackson but it made me wonder.
Is there any fantasy book/movie/story (besides the D&D franchise or material derived from that) that has an actual Dwelf in it?
I can't recall having ever seen one.
Half-dwarves and half-elves are common enough (with the other half being human), but Dwelfs seem to be an exceptionally rare breed.
