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.
Scandinavian mythology includes light-elves (Lioslfar) who dwell in the third space in heaven, dark-elves (Dcklfar), and black-elves (Svartalfar). The black-elves were skilled smiths, and the most skilled were reputed to be the sons of Ivaldi, the father of Idun.
The elves (light-elves) are often mentioned along with the Aesir, instead of the Vanir (a race of gods). The names Vanir and Alfar (light elves) may have been either synonymous, since the expression "Aesir and Alfar" meant "all the gods", or designating a difference in status between the major fertility gods, the Vanir, and the minor ones, the elves. The Van Freyr was the lord of lfheim (meaning "elvenhome"), the home of the light-elves, and he had as servants two elves: Byggvir and Beyla. Like the Vanir the elves were associated with fertility and, in late fall, the "alfablt" (elven sacrifice) was performed in the homes. It was secret, no strangers were allowed in the homes, and so next to nothing is known of it.
In 1954, Poul Anderson introduced grim Norse-style elves in his fantasy novel The Broken Sword and made them full-sized.Christopher Paolini's Eragon also features elves of a Nordic persuasion.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.
