Grégory Charlet studied fine arts in Tournai. In 1998, he cooperated on a book by the academy, called 'Envie de Fraise'. His participation got the attention of Eric Corbeyran, who suggested a cooperation. This resulted in the series 'Le Maître de Jeu', that started at Delcourt in 2000. In 2003, he started 'Kabbale' at Dargaud, doing both artwork and scenario.
