By the will of a blind chance, they found themselves infinitely far from home, in a world where there are no maps or geography textbooks, and only crumbs can be learned from the natives, and even those are often implausible. Everything else has to be learned through practice - on long hikes, further and further expanding the explored area, which is in no way similar to a city park... There are more than enough various threats here, and new ones are added to the already known enemies, and they are much more dangerous. At the same time, the most basic things are missing, and therefore any metal object is priceless. No matter what metal there is, you can’t even send a worn and torn rag to a landfill, because you can’t buy a new one in a store. But there is one place where you can get hold of metal, clothes, and medicine—there’s plenty of everything. But the trip there is so dangerous and difficult that it promises to eclipse all other expeditions.
