Primarchs Book 3 Fighting in the Great Crusade beside his staunchly anti-mystical brother Perturabo, the psychic primarch Magnus and his Legion of knowledge-seekers must walk a fine line between their mission and their own desire to learn forbidden secrets. READ IT BECAUSE Graham McNeill returns to a character he brought to life in the Horus Heresy series to tell a definitive tale of the one-eyed primarch. THE STORY Lord of the mystical and uncanny, Magnus the Red has long studied the ancient crafts of sorcery. A psyker without peer, save only for the Emperor himself, he commands his loyal followers of the Thousand Sons Legion in the Great Crusade, though also vigilant for any lost knowledge they might recover from the remains of dead human civilisations. Now, fighting alongside his brother Perturabo of the Iron Warriors, Magnus begins to foresee an approaching nexus of fate - will he remain true to their mutual aims, or divert his own efforts towards furthering his own mastery of the warp? Written by Graham McNeill.
