Warhammer: Guilliman Arrives in Another World

Roboute Guilliman, the last loyal Primarch and Imperial Regent, was pierced through the chest by Mortarion's scythe at the end of the Plague Wars. When he opened his eyes again, he found that he was locked in an underground cage, his hands in cheap iron shackles, and surrounded by ragged slaves. There were no loyal heirs and a ruined empire, only the rotten scar on his chest that was still oozing black blood, and a silver-haired boy who called himself Kyle told him: You were sold to the demons as a sacrifice. The soldiers of this world still wield long swords and crossbows, and the "magicians" of this world can burn people to ashes just by raising their hands, but they know nothing about the Milky Way, the subspace, or the Primarch... The human beings in this world are called "cattle", "sacrifice", and "goods". They are slaughtered one after another by those called "demons" like harvesting wheat and sacrificed to the so-called gods as food and sacrifices. However, the human empire does nothing and compromises to survive. Guilliman didn't know whether he was thrown into a new chess game by Tzeentch, or whether he had really traveled to a different world that had nothing to do with the galaxy. But when he saw the extinguished light in the eyes of those slaves, his hand had already tightened his grip on the Emperor's Sword. Free them. Exorcise the demons. Restore human dignity on this land. This is what he: the last Primarch, Regent of the Imperium, Son of the Emperor, is meant to do. "I am Roboute Guilliman, Son of the Emperor, Regent of the Empire, Lord of the Five Hundred Worlds... I will be the flame that consumes the gods."
