In the twenty-second century, humans invented machines and devices that enabled them to do more work in less time. Soon, space travel became prominent, and weapons became more advanced. However, several massive nuclear wars very nearly destroyed civilization, and wiped most of the modern weapons. Humans degraded to a more base state, still using the space travel technology, then gradually advanced to be able to use weapons such as swords, pikes and the like, and soon were back in the Middle Ages. But they were unable to go further, because the Creator, the maker of the universe, saw how destructive they could get and rendered them unable to upgrade.
