Elf, fairy, and other terms for nature spirits like pwcca, hobgoblin, Robin Goodfellow, the Scots brownie, and so forth are no longer clearly distinguished in popular English folklore, nor are similar terms in other European languages.
The twentieth-century philologist and fantasy writer J. R. R. Tolkien had little use for Shakepearean fairy portrayals or for Victorian diminutive fairy prettiness and whimsy, aligning his elves with the god-like and human-sized elves of Norse mythology, the Ljoslfar. He conceived a race of beings similar to humans but fairer, with greater spiritual powers, keener senses, and a closer empathy with nature. They are great smiths and fierce warriors on the side of good. Tolkien's Elves of Middle-earth are not deathless and can be killed by injury, and while they are sufficiently long-lived to be called immortal by humans, they do age.
The Svartalfar live in Svartalfheim. In some sources they are identified with the dwarfs of Nidavellir, who likewise had a reputation as skilled smiths. In general, however, elves and dwarfs are distinguished in surviving Norse literature.
In USA, Canada, and the United Kingdom, the modern children's folklore of Santa Claus typically includes diminutive, green-clad elves as Santa's assistants. They wrap Christmas gifts and make toys in a workshop located in the Arctic. In this portrayal, elves slightly resemble nimble and delicate versions of the dwarfs of Norse mythology. However, the elf legends are in fact, even older than Saint Nicholas, the bishop on whom Santa Claus was originally based.
There are also in the Heimskringla notions about a line of local kings who rule over lfheim, situated between the Gautelfr and the present border between Norway and Sweden on the Swedish westcoast. The last king is named Gandalf.In 1954, Poul Anderson introduced grim Norse-style elves in his fantasy novel The Broken Sword and made them full-sized.Wendy and Richard Pini's long-running comic book Elfquest attempts to avoid the usual Tolkienesque elven clichs by placing their elves in a setting inspired by Native American rather than European mythology. It later turns out that they are actually the descendants of a shape-shifting alien race rather than mythological beings.What remained of the belief in elves in German folklore was that they were mischievous pranksters that could cause disease to cattle and people, and bring bad dreams to sleepers. The German word for nightmare, Albtraum, means "elf dream". The archaic form Albdruck means "elf pressure"; it was believed that nightmares are a result of an elf sitting on the dreamer's chest.Purchase elven jewelry online in the largest elvish storeTad Williams's Memory, Sorrow, and Thorn trilogy focuses heavily on a long-lived, fair-skinned, magical race known as the Sithi, which are described as elves in all but name.The elves of Norse mythology have survived into folklore mainly as females. The lvor (Swedish, singular lva) were stunningly beautiful girls who lived in the forest with an elven king. They were long-lived and light-hearted in nature. They could be seen at night dancing over meadows. The circles they left were called lvdanser (elf dances) or lvringar (elf circles). If a human watched their dance, he would discover that even though only a few hours seemed to have passed, many years had passed in the real world. (This time phenomenon is retold in Tolkien's Lord of the Rings when the Fellowship of the Ring discovers that time seems to have run more slowly in elven Lothlrien. It also has a remote parallell in the Irish sdhe).
