Everyone knows the story of Krysolov from Gammeln . The story is very simple the magic blower lures hordes of rodents into the water, and they drown. Meanwhile, everyone forgets that rats swim perfectly . The story was brought to life in one of the cities of the Flat World .. But it all started with the fact that living in the basements of the Invisible University rats suddenly suddenly became smarter, learned to talk and formed the Clan. Then, these Educated Rats met Maurice, a street cat who turned out to be a cat unusual in every way. Firstly, he also knew how to talk (the consequences of living in the territory of the Invisible University), and secondly, he had an amazing business acumen. Maurice found a boy who could play the pipe, and the tale came to life.
