In An Echo, Resounding, a Labyrinth Lord-compatible guidebook, you’ll learn the arts of war and kingly rule in the untamed borderlands. Referees will find all the tools they need to build a savage land of adventure and bloody struggle, carving the foundations of empire into the very bones of their campaign. Players will find new talents as Champions of their lands, fighting for a noble cause or struggling to establish a beacon of light in the wilderness. And together, both will find new tools for domain management to bring the red-edged games of kings and princes within the grasp of fiercer souls!
