The Mythos is older than humanity, Gods, and Titans, with an unknowable otherness that can shatter them all. This slumbering horror lurks in the shadows, carrying out its alien machinations with little regard for those beneath it until it requires pawns. Those that touch the Mythos are forever altered. The World explodes into full view for them, leaving some shattered, others power-mad, and still others knowing only secrecy protects humanity. Mythos Scions fair little better, empowered by these alien beings that alter their very essence, the ability to break Fate and leave the walls of reality weaker in their wake. These human embodiments of the Mythos are not good or evil; such easily definable morality is for lesser beings. What does one do when their power comes with a cost?

Some highlights of Masks of the Mythos include: An entire new pantheon: the Mythos; A trove of new Callings and relics; Expanded investigation rules; A detailed tour of the Miskatonic Hollow, including Arkham and Innsmouth; An introductory scenario for a new band of Scions. Do you have the willpower to face the Mythos? To become the Mythos?
