The shadow of Cthulhu threatens Gassin and the world! Explore the village, escape monstrous traps, and complete the ritual to seal the black stone idol. A major Halloween family treasure hunt, free and self-guided.
Thanks to you, back in 1666, Cali the Skinner resumed her fierce battle against sea monsters. But today, 361 years later, an even more terrifying threat awakens from the depths under the influence of Cthulhu, the most dreadful of the Great Old Ones.
Off the coast, across a wild Gulf beneath an apocalyptic storm, the pirate leads a heroic fight. During a perilous boarding, she managed to wrench the sea creatures' most precious artifact from their grasp: a black stone statuette fallen from the stars, vital to deciding the fate of the world. She entrusts it to you: the idol must be neutralized and hidden before the cursed city of the abyss fully emerges from the sea.
A thrilling adventure in the heart of the old village
Armed with your game booklet, set out with your family through Gassin’s steep alleys, vaulted passages, and medieval ramparts to save the village and help Cali in her battle:
Gather the seven ancestral alchemical ingredients essential to completing the grand petrification ritual and stripping the relic of its powers.
Foil the traps and false trails: beware, some stops are decoys meant to slow you down!
Search every corner to crack secret codes hidden in the stone walls, fountains, and ancient doors.
