The hero of the novel, Nick Lambert, born and raised in the state of OAM (Union of Anglizonian Worlds), having experienced many dangerous adventures, having been captured by the Urians, gray-faced people (and maybe not people at all), ends up in a distant region of space, where The Primar Empire is located. Here he feels at home, which is natural. Primars are people, one of the branches of earthly humanity scattered in space. From Nick they learn about the existence of the Other Branch, as they call it... Meanwhile, the Urians are capturing one planet after another. There is a brutal war going on between the mayors and the Urayans. The mayors' intelligence decides to establish contact with OAM. Nick Lambert, who joined the ranks of the “corsairs,” plays a decisive role in this. Fate brings him together with Edgar Hubert, through whose fault he once found himself on the brink of death. Now they are allies...
