Mragh is one of the strongest and most experienced warriors of a tribe of monsters that lives among the ruins of a large and old city. Mostly underground. It's humid there. The Sun or another luminary is always shining on the surface. A conflict is brewing in the tribe. The leader is Dorf, and Mrag anticipates him, noting that among their fellow tribesmen there are more and more silent ones who are adopting animal habits, and their children no longer know how to talk and move on all fours. There are more and more Silents as they multiply faster, begin to dominate and realize their numerical and physical superiority. A new tribe is formed within the tribe, and authorities are secretly duplicated. The Silent Ones increasingly play hunting, and jokingly choose a reasonable tribesman as a victim. Dorf and Mrag understand that it is necessary to refresh the blood in order to stop the degeneration of the tribe. There is information left in the city, information about the creatures that inhabited it previously. Mrag undertakes several long trips to different parts of the land.
