When science fails, machines fall dormant, and mutated flesh becomes the sole truth, Hu Yan descends from a rain of living bodies. Branded a disaster and shunned by every pure lifeform, no one knows that he is the last spark in this decaying universe. He touches a discarded gun, and its machine spirit awakens. He enters a sanctuary, and steel sings again. He kills a throne-holder to claim a fragment of the old rules, slays an ancient god to seize its laws, and destroys an Outer God in pursuit of truth. From scavenger on a junk planet, to the Empire's new spark, to Lord of All Machines who reclaims the Machine God's throne, this time he will let the science and order lost for countless millennia shine across the galaxy once more.
