The city of Oeuvis is known for its busy streets and flourishing market, but the most prominent piece is its cathedrale: Notre Dame. She is a place of sanctuary, as well as the origin of all the town's energy. However, rumours say that inside the archdeacon's workshop lives an unknown creature. A misshapen monster with two tails who wishes nothing more than to see the world and be free. Little does he know that the appearance of a single hedgehog will change his and the city's life forever.
