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.
Modern fantasy literature has revived the elves as a race distinct from fairies. Fantasy elves are different from Norse elves, but are more akin to that older mythology and to the Irish sdhe than to folktale elves.
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).Elves were imported into Britain with the Anglo-Saxons.Post-Tolkien literary elves (popularized by the Dungeons & Dragons role-playing game) tend to be human-sized or only slightly smaller than humans, and tend also to be capable warriors, especially skilled in archery. Terms like hob or brownie or other genuine regional folklore terms are seldom used of such creatures: they are unlikely to sneak in at night and help a cobbler mend his shoes. The canonical role-playing style elf is Deedlit, a major character of the anime series Record of Lodoss War.Tad 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 Scandinavian elves were of human size, which allowed "normal" human interactions: for example, in Hrlf Kraki's saga, the Danish king Helgi finds an elf-woman on an island and rapes her. Famous men could be elevated to the rank of elves after death, and in one such case, the full-sized smith hero Vlund is called an elf.Tolkien's elves were enemies of goblins and orcs and had a longstanding quarrel with the dwarves: these motifs also often reappear in Tolkien-inspired works. In gaming, and to some extent fantasy, elves have a great depth of knowledge (especially regarding magic) due to a racial inclination as well as their extreme age. There are also "dark elves" popularized by TSR as drow.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.
