Sébastien Grenier works the old-fashioned way, on large formats with real paint that stains! While most of his time is devoted to comics, he also practices illustration (comic book covers, novels, video games, RPGcards) and creates commissioned paintings for collectors. From 2008 to 2014, he illustrated the Arawn comics series which was published in the USA in Heavy Metal magazine. He is currently working on La Cathédrale des abymes with Jean-Luc Istin for the screenplay, whose first 3 volumes were released in 2018 and 2019 (Soleil). In 2020, he worked on a volume from the Orcs et Gobelins series, in parallel with volume 4 of La Cathédrale des Abymes. He also practices the electric guitar and remains active in the metal scene (concerts, album recordings).
