The Ruins of Lemuria
A fantasy campaign setting centered on the ruins of Lemuria, a powerful civilization whose advanced science and magic lie buried across the New World. Colonists, scholars, tribal warriors, mystics, and adventurers explore forgotten temples and tombs in search of lost knowledge, magical artifacts, and treasure. The supplement provides a framework for incorporating these expeditions into high-fantasy RPG campaigns. Discoveries can alter the course of history, heal diseases, end wars, or threaten civilization, while rival factions compete to control the ruins and their secrets.
