Colonization of a planet with an oxygen atmosphere and rich flora and fauna. The initial period, when general workers arrive after the prospectors and lodgers. Unexpectedly for the expedition, not far from the landing site there were other intelligent, as well as semi-intelligent and even completely unreasonable, but well-organized creatures capable of joint meaningful activity. Everyone had their own problems and difficulties. In order not only to survive, but also to settle down comfortably, the settlers had to strain not only their strength, but also their intelligence. Sudden meetings, adventures, conflicts and mutual assistance - all that fell to the lot of earthlings to the fullest.
