Horus Heresy: Know no Fear (English)

Unaware of the extensive heresy, Roboute Guilliman follows the war master's increasingly cryptic orders. Guilliman returns to Ultramar to muster his legions for war against the orks gathering in the Veridian system. Without warning, their allies, the Word Bearers, launch a devastating attack on Calth, slaughtering all who stand in their way. This confirms the worst scenario Guilliman can imagine - Lorgar intends to settle their disagreement once and for all! The Ultramarines are drawn into a bloody battle against the traitors, who summon demonic forces. A brutal conflict where neither side can hope for victory.
