But that too had changed. When the Emperor’s sons, the great Primarchs, had been sundered from his side and scattered across the galaxy, the Dusk Raiders joined their brother Space Marine Legions and the Master of Mankind in the Great Crusade that began the Age of the Imperium. Garro had been there as the Emperor crossed the galaxy in search of his lost sons – Sanguinius, Ferrus Manus, Roboute Guilliman, Magnus the Red and all the rest. With each reunion, the Lord of Mankind gave his sons the command of the Astartes forces that had been created in their image. When at last the Emperor came to Barbarus and discovered the gaunt warrior foundling named Mortarion who lead its oppressed people, he knew he had located the Primarch of the XIVth Legion.
