Chronicles of Skythia
The Breach Wall is a massive fortification built across the southern horn of the continent and reinforced with powerful magicks. Extensive slave labour was used to build it after the First Chaos War resulted in massed devastation across most of the continet. It guards the Chaos Bore dissapating much of it’s energy and is constantly manned to contain any threats posed by escaping creatures. Criminals from every major city are sent here to defend the wall, blindfolded much of the way and with no way to bring enough food and water with them to escape, they have no choice but to defend the wall or perish.
