The Brandlands are a region of scarred earth, roughly a hundred miles long by 20 miles wide that sit along the border between Valanthas and the Holy Launcian Empire.

At the end of the Liberation War, Erisvan's armies swept through the eastern Freelands, destroying a half-dozen major cities including the capitals of Launcia and Himo. In a pitched battle with another Heretic, Kendrick, she blasted the region that would become the Brandlands with a burst of destructive energy. Since that date, the area has been slow to regrow. Much of the ground is covered with the ashes of the many forest fires created by the Heretic, as well as deep gouges in the land which expose rocks and long-forgotten caverns.
