Nether Darkness

The Nether Dark is the area outside Arda, the world. Up until the second age Arda is a disc. The Nether Dark in these periods is the area around and beyond this disc. When Numenor is destroyed, the world is made spherical. The Nether Dark then becomes the infinite space around the globe. In the Dark there are two main features: The Timeless Halls of Eru Iluvatar and Arda itself. It is an infnite black void, containing nothing but stars. At the end of the first age Morgoth was cast into the Darkness by Manw ë.
