The galaxy burns and brother goes against brother as the conflict sparked by the betrayal of his beloved son reaches its fateful end. Warmaster Horus was victorious. His vast fleet is finally approaching Terra and the venerable throne of his hated father. Many fell to bring this moment closer, their stories are the ashes on which the Heresy was born and flourished. Others played their small roles, becoming drops in the ocean of war and blood. None of this matters now. Terra looks to the sky, mobilizing her defenses. Armies gather, heroes raise their swords, ordinary people seek cover. War is coming. And nothing can stop her.
