But it is said that at the last, Morgoth will succeed in breaking the doors of Night, and return to Arda to complete the devastation he began, and that battle we call the Dagor Dagorath. What lies beyond that we do not know, but some hold that Turin will return from beyond the world, with the great heroes of Men, to avenge themselves for the years of grief and pain, and Eru will open the leaguer of the Timeless Halls and set aright all that has been Marred. But what lies beyond the Valar forgot when they bound themselves to Arda, and so we do not know. Men might, but they do not return, so none have been able to tell us.
