The Discworld novels by Terry Pratchett feature extradimensional creatures called elves, that go back to the old myths of cradle-robbing fairies. The book Lords and Ladies is about an encounter with "the fair folk".In the Nordic countries where elves have since become associated with Christmas, elves are clad all in red and have long beards and black boots. On Christmas Eve, one must give the elves a bowl of porridge to keep them from playing pranks. In Iceland, from December 12 until Christmas Eve, thirteen elves called the Yule lads visit homes, a lad each day for 13 days, and play tricks on the children, as well as leaving presents for them.
German folklore held that elves had a particular fondness for children and would appear to those about to die, rather like the Irish banshee. This aspect of the legend was immortalised by Goethe in his poem Der Erlknig, later set to music by Schubert.
Christopher Paolini's Eragon also features elves of a Nordic persuasion.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.Tolkien's The Lord of the Rings (1954-1958), became astoundingly popular and was much imitated. In the 1960s and afterwards, elves similar to those in Tolkien's novels became staple non-human characters in high fantasy works and in fantasy role-playing games (RPGs).Purchase elven jewelry online in the largest elvish storeIn 1954, Poul Anderson introduced grim Norse-style elves in his fantasy novel The Broken Sword and made them full-sized.
