Horus heresy. Book 9. Calt. The volcano is alive. Forgotten empire. Abnet D., and others.

The Kalta heresy mark came to the Calt without warning. In just a few hours, the bearing word destroyed their former brothers - the proud soldiers of the Ultramarins. Now that the world is burned out by outbreaks of the mutilated star of Veridia, the survivors should give the XVII legion and their dishonest allies or meet their curse in the gloomy shelters of the arcologies under the surface of the planet. The volcano has been living in the Icensky massacre Warriors from the Legion of Salamander for a long time and unsuccessfully trying to find their defeated primarch. They do not know that the volcano, to their misfortune, is still alive... and languishes in captivity, where he serves the toy to a cruel jailer, his own brother Konrad Kurtz. Under terrible torture, designed to break both the body and the spirit, the volcano will see the depth of the moral fall of the night ghost - and will reveal a secret that can change the course of the whole war. The forgotten empire is far on the eastern outskirts of the world of Ultramar. Having survived the attack of a word carrying a word and the shadow crusade followed by him against five hundred worlds, the primarch of Ultramarinov Robut Gilliman now collects associates in Macragge - as he suggests, a new future citadel of humanity. Residents of Ultramar are isolated from Terra with a terrible warp-scheme. The rest of the galaxy is covered by the fire of the war. With the arrival of many refugees, the differences between friends and enemies begin to wash. Can Gilliman be able to compete in power with the apostate Horus?
