Les Mondes engloutis

In the mid-1980s, French publisher Casterman released Les Mondes engloutis (The Sunken Worlds), a four-issue comic series that served as a prequel to the animated television series of the same name. Created by the show's original team, the comic explored the backstory of the futuristic, post-apocalyptic world of Arkadia, delving into the events that led to the civilization's descent beneath the Earth's surface. While the series was brief, it remains a key artifact for fans of the cult Franco-Belgian cartoon, expanding its mythology through the detailed visual storytelling of the era.
