The Chronolith Engine
Seventeen meters below the streets, engineer Astrid Volkov's scanner picks up a pulse that matches no geological survey, no power grid, no known technology, an ancient engine buried beneath the bones of the old world. When she reports the anomaly, it draws the attention of Director Kaelen Thresher, who sees a weapon, and the gaze of The Archivist, a rogue AI that has been waiting for this signal across decades of silence. As Tech-Priest Murn and Professor Sable Orin race to decode the engine's purpose, Ministry Operative Riven closes in to secure it by any means, and transmissions from Vathi Elder Sirok warn of a reckoning tied to humanity's forgotten colonies. Station Overseer Draven, smuggler Jaxon Quill, and the mercenary Lucan Veer each carry pieces of the puzzle, along with agendas of their own, while the recorded testimony of Colony Commander Harlan hints at a catastrophe already set in motion. Admiral Valerius Crane watches from orbit, High Priestess Izia guards secrets of the Vathi, and every activation of the Chronolith sends new echoes rippling backward through time. Astrid must decide whether to trust the strangers circling the relic, silence the engine forever, or light it up and risk rewriting the present into something unrecognizable.
