Black Forests

Situated north of Naggaroth, the Black Forests cover the landscape with dark, forbidding trees of ill-favoured aspect. These forests sprawl with a mixture of towering pines, black trees and a bleak desolation that sears the soul with its unending vistas of emptiness. The ground is cloaked in shadows as chained gangs of slaves from the principle dockyards of the Witch King fell the massive timbers -- dragging them back for dark uses in Clar Karond, the Tower of Doom. Strange monoliths and ancient ruins dot the few desolate clearings.
