: Anyone correct me if I'm wrong here.

You're correct, I'll just expand upon the topic. I'm sure Michael will correct me if I'm wrong on anything.

Dagor Dagorath is basically the end of the world, in a way, for Arda. The Valar become lax in their duties of guardianship, and Morgoth returns from the Outside. He destroys the sun and the moon. Soon after though Earendil comes and sears him from the sky. Then Turin returns from the dead, and is raised up to be one of the Ainur (I think a Maiar). Túrin, Tulkas, and Eonwë do battle with Morgoth. Finally, Túrin slays Morgoth with The Black Sword, Gurthang. Then Fëanor is recalled from the Halls of Mandos. Eärendil surrenders his Silmaril, and the other two are found. Fëanor opens them and revives the Two Trees. The world is remade, and things are as they are supposed to be. All the elves are reincarnated, though I do not recall the fate of men in this scenario.

Overall, the story is a little outdated. It takes place supposedly in a flat world, and I don't think it takes into consideration that some elves are reincarnated before the end.

Anyway, hope that helps. And Michael, please correct any errors, I know you will.
