The story takes place in a world where the development of advanced technologies has led to a catastrophic event known as the Great Transition, which caused a global ecological disaster and the collapse of society. The protagonist, a young man named Artyom, discovers a mysterious underground laboratory that holds the key to understanding the cause of the Great Transition and potentially saving humanity. The book is set in a post-apocalyptic world where the sun never shines and the sky is always darkened by a thick layer of smog. The air is toxic, and the only living beings are those who have adapted to the new environment. The protagonist, Artyom, is a young man who lives in an underground bunker with his family. He spends most of his time exploring the ruins of the pre-Great Transition world and searching for clues about what caused the disaster. One day, he discovers a hidden underground laboratory filled with strange devices and artifacts from the past. As he delves deeper into the labyrinthine facility, he uncovers a sinister plot to control the minds of the survivors and use them for nefarious purposes. Artyom soon realizes that the only way to save humanity is to understand the technology that drove the Great Transition and find a way to reverse its effects. However, this task proves difficult as the technologies are so advanced that they are beyond human comprehension.
