Shadowlands are places of tainted essence, where Creation and the Underworld overlap and merge into a single, benighted landscape. Most are capable of supporting life, though it tends to be a stunted and sickly life. During the day, the sun is obscured by clouds, while at night, alien stars emerge. One must be careful leaving a shadowland. Crossing the borders during the day will lead one into Creation, but at night, the traveller will pass into the Underworld, with all it’s accordant dangers.
