Century XVII. Mountain range of the Pyrenees, Iberian peninsula. A peasant from Cerdaña dies in strange circumstances. Suspecting the supernatural and evil character of the event, a priest is sent to investigate the incident. But there is more ancient and dangerous secret hidden in the heart of some cursed mountains, remembered by the few survivors of a time in which the fog was able to cover too discouraging truths... Now that veil has been broken and the threat is released. If nobody restrains it, the chaos will explode. The night is falling in which the fables that fired imagination of the little ones will turn into reality to frighten the most skeptic men... Who would be able to maintain the sanity when the firm pillars that sustain the reality, collapse? Magic, witchcraft and ancestral secrets will shake the orthodoxy of Christianity. An adventure that will take us back to the depths of the Pyrenees, to a frontier land, where the impossible seems more real than the common sense longs for. Would you be one of those who accepts the challenge, who pursues the most uncomfortable and archaic mysteries? Every tree, hill, lake, and cave belongs to two worlds; one of them we ignore. Its exiled inhabitants have fired the fantasy of popular folklore... until now. Could you reveal its presence? If you delve into their domains, you could get to know them. But you'll have to pay a price. In front, the old paths that lead us toward them are outlined and they are waiting for you. Do you have enough courage, or the necessary madness, to travel across them?
