Dagor Dagorath

The Dagor Dagorath (Sindarin for Battle of Battles) is a fictional battle described in the legendarium of J. R. R. Tolkien. As Tolkien's works were conceived as a fictional "forgotten history" of the world, the Dagor Dagorath represents the coming End of the World, and is often referred to as simply "The End". As Tolkien originally wrote it, The Silmarillion ends with a prophecy by Mandos about the end of the world. The published Silmarillion ends instead with the last paragraph of Valaquenta. This was because Tolkien had abandoned the idea of the "second prophecy of Mandos", and the Valaquenta text, much later, contradicted it openly. However, references to the final battle remain in the published Silmarillion, such as a statement at the end of the Akallabêth that Ar-Pharazôn and his mortal warriors who had set foot on Aman were buried by falling hills, imprisoned in the Caves of the Forgotten until the "Last Battle and Day of Doom". Christopher Tolkien sees the account as similar to the Nordic legend of Ragnarök and J. R. R. Tolkien also made this connection in some of his letters.

According to the Second Prophecy of Mandos, included in The Shaping of Middle-earth and similar versions in later volumes of the History of Middle-earth series,Morgoth (the source and personification of evil in Tolkien's Middle-earth universe) will discover how to break the Door of Night, and will destroy the Sun and the Moon. For the love of these, Eärendil will return from the sky and shall meet Tulkas, Eönwë, and Túrin Turambar on the plains of Valinor.
