Masks of the Mythos
The Mythos predates humanity, Gods, and Titans, and its alien influence reshapes those who encounter it. Mythos Scions draw power from these unknowable beings, gaining the ability to break Fate while weakening the boundaries of reality. This supplement introduces a new Mythos pantheon, Callings, and relics, along with expanded investigation rules. It details Miskatonic Hollow, including Arkham and Innsmouth, and includes an introductory scenario for a new band of Scions.
