In the original "fantasy" book, The Hobbit, dwarves and elves weren't hostile to each other. Thorin and Elrond, and their followers, cooperated. Elrond was hospitable, and Thorin shared what he learned about the map to the Lonely Mountain and the key, etc. It was only when the dwarves arrived in Mirkwood that they were imprisoned by the wood elves (led by Thranduil), and that was only because a big misunderstanding.
Anyway, the dwarf-elf dynamic is clear in Tolkien: dwarves don't hate elves, and in fact, they have both cooperated over the ages.
Flash forward to later books and computer games, and there's a dwarf-elf rivalry, and even hostility. In the "Dragon Age" games, there's banter between dwarves and elves (but most of it is good-natured). But in the "Witcher" games, elves (or at least the Scoi'atel) want to destroy humanity, and humans discriminate against the elves. Dwarves ... I dunno, I haven't figured out the elf-dwarf or human-dwarf dynamic in "The Witcher" yet.
So what's the origin of all this? Why does this always happen? Any ideas? I'm confused. *shrug*
