Now a renegade among renegades, he is loathed by those he once called brother, and even the most degraded of Chaos Space Marines fear his name. Exiled for his dark experiments, Bile has retreated deep into the Eye of Terror, leaving a trail of twisted abominations in his wake. But when a former student brings word of the ultimate prize for the taking, Bile is unable to resist being drawn once more into the cauldron of war. For in seizing this prize, Fabius Bile might yet discover the one secret his has been unable to unlock... the secret which will prevent his inevitable doom.
