"Calls Of Mythos" Manual

Welcome to the New Era of Mythos.

Inspired by the legendary tabletop RPG and the classic Lovecraftian tale Call of Cthulhu, Calls of Mythos reimagines cosmic horror through the lens of the modern world. In this cinematic, narrative-driven game, players step into a reality where nightmares bleed into everyday life—and where ancient beings lurk just beyond the veil.

Set in the present day, Calls of Mythos trades Victorian gloom for urban shadows, digital dread, and the twisted horrors of our modern psyche. The world is more connected, more informed… and more vulnerable than ever. With access to media, film, and myth, the boundaries of terror are stretched into madness.

Gameplay blends streamlined mechanics with immersive storytelling. Characters may forge pacts with incomprehensible entities or gain strange powers—but every gift comes at a price. The combat system emphasizes narrative weight, while sanity, corruption, and personal scars shape every action. Death is sudden. Madness is creeping. And the truth is never simple.

Designed for one-shots and short campaigns, the system is accessible to both seasoned Keepers and first-time players. Each scenario is a self-contained descent into mystery—perfect for groups seeking a haunting story with lasting impact.

Face the impossible. Resist the madness.

And discover what lies beneath the surface of reality.

Dare to play. Dare to remember. Dare to lose your mind.

This is Calls of Mythos.
