In the fantasy of J. R. R. Tolkien, the Dwarves are a race inhabiting Middle-earth, the central continent of Arda in an imagined mythological past. They are based on the dwarfs of Germanic myths who were small humanoids that lived in mountains, practising mining, metallurgy, blacksmithing and jewellery. Tolkien described them as tough, warlike, and lovers of stone and craftsmanship.
Tolkien found dwarves in Norse mythology. Here the god Thor talks to the dwarf Alviss to prevent him from marrying his daughter Þrúðr; at dawn Alviss turns to stone. Drawing by W. G. Collingwood, 1908

Middle-earth is the setting of much of the English writer J. R. R. Tolkien's fantasy. The term is equivalent to the Miðgarðr of Norse mythology and Middangeard in Old English works, including Beowulf. Middle-earth is the human-inhabited world, that is, the central continent of the Earth, in Tolkien's imagined mythological past. Tolkien's most widely read works, The Hobbit and The Lord of the Rings, are set entirely in Middle-earth. "Middle-earth" has also become a short-hand term for Tolkien's legendarium, his large body of fantasy writings, and for the entirety of his fictional world.
