Under the name of Les Terres Creuses Luc and François Schuiten explored a three-volume fantasy world of the Hollow Earths. In turns dreamlike, poetic or frightening - and often more radical otherness than the Obscure Cities. Glowing imagination and often grandiose, a reference to the comic science fiction.
In these five stories many amazing worlds to discover, with the thread of the mysterious odyssey Fanelli, these fabulous winged creatures only things in the universe, to occur from one world to another. The short stories of Luc and François Schuiten gathered in Carapaces were originally published at the turn of the 70s and 80s in Heavy Metal magazine.
