The Mythos

A shared world of cosmic dread. Old things sleep beneath the sea and between the stars, scholars go looking for them anyway, and the price of knowing is always paid in full. Start in the hill country and harbor towns of 1920s Massachusetts, or take the Mythos anywhere and any when the canon can support it.

Grounded in the public-domain fiction of H. P. Lovecraft and his circle, published before 1931. Shared Myth is a fan community and is not affiliated with any estate, publisher, or game company.
