The only way out is back. After narrowly escaping the Sol System with the last of the Prophet species on board, Captain Vance, Kira, Tyrone, and Teesha find themselves trapped between two overwhelming forces: the tyrannical Agency they defied and the cold, crystalline vengeance of the cosmic entity known as the Architect. Their battered ship, The Horizon, is powered by forbidden Aetherian science and held together by sheer willpower, navigating space under an 87% probability of structural collapse. But the real structural danger lies in the truth: the Agency didn't want the Prophets captured they wanted them protected. Rushing back to Phobos, the crew must infiltrate the command center of Director Rho, the woman who betrayed them, only to discover her betrayal was a calculated sacrifice for a greater good. The Cleaners are already here, hidden in the dark corners of the Sol System, hunting the ancient power locked inside the colony. With time running out, the crew must awaken the entire Prophet Collective in a desperate gamble that transforms their ship into a weapon of chaotic energy. But even with a unified front, victory is impossible. The war is no longer about survival. It's about finality. Following a devastating confrontation, the crew joins a hidden, cosmic Resistance, and the Prophet Collective delivers the ultimate, terrifying prophecy: to save the universe, they must destroy the Architect's home world.
