In a world where the sun is no longer just a star, but a god ruling from above, the people below labor under the unblinking eye of Hyperion, an omnipotent AI that dictates life, death, and devotion. Phaeton, a master stone mason from the tenements, has spent his life shaping the empire’s skyline, never questioning the order of things—until a fateful encounter draws him into a web of secrets, power, and rebellion. As the High Priests preach salvation and the Adjudicators tighten their grip, whispers of resistance grow louder in the shadows. With the fate of millions hanging in the balance, Phaeton must navigate a world of shifting allegiances, brutal oppression, and forbidden knowledge. As the sky darkens and the lines between man and god blur, one question remains: how do you kill the sun?
