中土世界的歷史
The War of the Jewels (1994) is the 11th volume of Christopher Tolkien's series "The History of Middle-earth", analysing the unpublished manuscripts of his father J. R. R. Tolkien. It is the second of two volumes—"Morgoth's Ring" being the first—to explore the later 1951 "Silmarillion" drafts (those written after the completion of "The Lord of the Rings").
