The people suffer under the centuries-long rule of the Moon Throne. The royal family—the despotic emperor and his monstrous sons, the Three Terrors—hold the countryside in their choking grip. They bleed the land and oppress the citizens with the frightful powers they inherited from the god locked under their palace.

"Fino a che non diventeranno coscienti del loro potere, non saranno mai capaci di ribellarsi e, fino a che non saranno liberati, non diventeranno mai coscienti del loro potere." L'azione si svolge in un futuro prossimo del mondo (l'anno 1984) in cui il potere si concentra in tre immensi superstati: Oceania, Eurasia ed Estasia. Al vertice del potere politico in Oceania c'è il Grande Fratello, onnisciente e infallibile, che nessuno ha visto di persona ma di cui ovunque sono visibili grandi manifesti.

Piranesi lives in the House. Perhaps he always has. In his notebooks, day after day, he makes a clear and careful record of its wonders: the labyrinth of halls, the thousands upon thousands of statues, the tides that thunder up staircases, the clouds that move in slow procession through the upper halls. On Tuesdays and Fridays Piranesi sees his friend, the Other. At other times he brings tributes of food to the Dead. But mostly, he is alone.

Brother Diaz has been summoned to the Sacred City, where he is certain a commendation and grand holy assignment awaits him. But his new flock is made up of unrepentant murderers, practitioners of ghastly magic, and outright monsters. The mission he is tasked with will require bloody measures from them all in order to achieve its righteous ends. Elves lurk at our borders and hunger for our flesh, while greedy princes care for nothing but their own ambitions and comfort. With a hellish journey before him, it's a good thing Brother Diaz has the devils on his side.

After the old gods warred and drove themselves to extinction, the cataclysm of their fall shattered the land of Vigrio. Now, power-hungry jarls carve out petty kingdoms, and monsters stalk the shadow-haunted woods and mountains. A world where the bones of the dead gods still hold great power, promising fame, and fortune for those brave - or desperate - enough to seek them out. As whispers of war echo over the plains and across the fjords, fate follows the footsteps of three people. All three will shape the fate of the world, as it once more teeters on the edge of chaos.
