Desolation of Nagash

The Desolation of Nagash is a parched desert littered with the wind-polished bones of a forgotten army that fell in battle against Nagash centuries ago. On certain nights it is said the restless spirits of the slain rise up and re-enact their defeat, cursed by Nagash to remember their failure every time the full baleful glow of Morrslieb is seen in the sky. Such is the fate of those foolish enough to they can storm the gates of Nagashizzar.
