The University of Riotspolis has an unusual education system. At a very young age, every citizen takes an aptitude test to determine the career path they should follow. Kenjy is part of a small minority of geniuses who work on mining exploration techniques. Thanks to his mice and their sensors, this young mastermind enables the cartographers of the Alma Mater to produce extremely detailed maps of all the cavities surrounding Riotspolis, and all that thanks to an ultrasonic gramophone!
It was during recent work on the new Clint City subway line that the underground shelter, housing Riotspolis, was drilled apart. This Utopian city, dreamt up by wise men at the turn of the century, could now wave goodbye to its tranquility and isolation. Unsurprisingly upset by this turn of events, the Riotsville Council, led by the Patriarch Pericles, decided that the time had come for them to at last emerge from their isolation and impose their “wise rulings” on this barbaric bunch of hoodlums inhabiting the surface.
