Dead Lands
The Dead Lands are the name given to the valley between the mountains of Agruk and West Chedonc. The valley is extremely dangerous, with geysers of flame, clouds of deadly poison fog, poisonous plant life, and tons of creatures that will kill and eat anything they see. Not even orcs dare go near the place.
Unfortunately, because of its location merchants from Cireth must pass through its tail in order to do international trade, as the only alternative is passing through the White Forest.
