In this world, reminiscent of our Middle Ages, intrigues are always woven and wars do not subside. People there live in fear of otherworldly forces - the Tyranny of Night. The Grail Emperor is at enmity with the Brothian patriarch, and he dreams of organizing another sacred campaign against the Pramans and other infidels. In the west and east, dozens of large and small states are at war with each other. Meanwhile, the ring of ice is increasingly enveloping the civilized world. The Praman warrior-slave Els Tage manages the hitherto unthinkable - his squad kills the powerful creature of the Night without resorting to witchcraft. Does this mean the imminent end of Tyranny? Will people be able to prevail over the eternal enemy? The owner sends Els to the western domains to spy on the patriarch and his minions, but Tage does not even suspect that the Weapons of the Night, that is, the gods themselves, have now turned against him.
