A "holy meteorite" fell from the center of the Holy Roman Empire, bringing with it the miraculous mineral "holy pyroxene". With this, the empire nearly unified the European continent and regarded it as a gift from God.
However, this gift is a curse. When Inquisitor Ludwig investigated the strange withering incident in the border village, he discovered that the dead were not caused by demons, but that the life was completely sucked out like a candle. All clues point to the sacred lifeline of the empire - the Holy Pyroxene Mine. When he touches the truth, what awaits him is not a reward, but an assassination attempt from the top of the Holy See.
On the way to escape, he met the "cannon maker" who only believed in gunpowder and steel, and the "pale nun" who was a container of the empire's power and painfully felt the passage of life. He finally discovered that the glory of the empire was actually a big lie fueled by hundreds of millions of people.
Faith completely collapsed, and the judge turned into a rebel against God. He must unite all enslaved mortals, use fragile flesh and blood, roaring gunpowder, and unyielding will to launch a world-shaking mortal war against the temple made of corpses and lies.
