A vast corrupted region north of the Borderlands, extending from the Mountains of Dhoom to Shayol Ghul. Warped by the Dark One's influence, the Blight teems with twisted vegetation and deadly creatures. The land itself is dangerous, with plants that can kill and animals that are universally hostile. It is home to Trollocs, Myrddraal, and other Shadowspawn. The Borderland nations - Shienar, Arafel, Kandor, and Saldaea - stand as humanity's shield against the Blight.
