Exactly a year has passed since the moment when old Earth ceased to exist in the vast expanses of the Universe. The people who survived this catastrophe were located at the only mega-base deployed on Mars. The proximity to the Sun and the lack of natural food made the living conditions here worse and worse. Therefore, at a large council under the leadership of the head of the station, Professor Sergeev, a decision was made: to attempt to search for a new planet that would be suitable for the life of earthlings. Evis, where the crew of the interplanetary spacecraft Buran managed to visit, was declared unsuitable for the life of more highly developed people. There already existed its own civilization and system, comparable only to the times of the earthly Middle Ages.
