Guido Tognocchi is an actor. You might recognize him from a commercial or a crime drama. Matter of fact, his face is more familiar to TV audiences than it is to himself. And in the small village of Pietralba, nestled in the marble rock of the Apuan Alps, fame means nothing.

It all began with a concerned letter from his brother. From that moment on, every feeling of certainty vanished. Guido went back to his native village in the mountains, where he could sense the presence of something ancient and dark, something that didn't wish to be found.

Guido must now cross the gloomy, misty village, decipher cryptic riddles and sift through mysterious documents, all while being immersed in the silence of the Apuan Alps. He has nothing to depend on but his senses, his wits and internal compass.

In Marmorea every shadow is suspect, every detail is a clue to stay alive and move forward.

Will you unravel the secrets of Pietralba?
