Angelic beings, the Valar, live in the centre of Arda, lit by two enormous lamps, Illuin and Ormal, atop enormous pillars of rock. The Years of the Lamps are abruptly brought to an end when the lamps are destroyed by the fallen Vala Melkor; the powerful fiery light spills out and destroys everything around it. The world is remade with new seas and reshaped continents, no longer symmetrical; the Valar leave Middle-earth for Valinor.
