He has many names: Lord of the Clones, Freshener, Progenitor. He, insidious and depraved, brings fear to people and monsters. The former chief apothecary of the Children of the Emperor, a madman known as Fabius Bile, has incomparable knowledge of genetic transformations. Now he is one of the most famous renegades. Those who used to be called brothers hate him, and even the most downcast space marines of Chaos are afraid of one sound of his name. Once banished for his creepy experiments, Bile retreated into the depths of the Eye of Terror, leaving behind the result of his works - ghoulish monsters. But when a former student brings news of a valuable ship that is just waiting for the invader, Bile, unable to bear it, again rushes into the crucible of war. Having obtained this ship, he may pick up the key to the only mystery that has not yielded to him so far... A riddle that can save him from imminent death.
