Il y a un sorcier à Champignac, by Franquin, is the second album of the Spirou et Fantasio series, and the first to tell a long intricate story in what would become the Spirou tradition, in contrast to the previous short format stories. After serial publication in Spirou magazine, it was released as a complete hardcover album in 1951. This work introduces several key characters in the series, and the village of Champignac-en-Cambrousse (a name derived from the French word for mushrooms, and 'cambrousse' meaning rural backwater).
