Cauchemar joined forces with Arkelwan and Vincent Mondiot to create another fictional setting, Mirinar. Mirinar is the universe where the novel Teliam Vore (written by Vincent Mondiot and Cauchemar) takes place, as well as numerous illustrations, maps and drafts by Arkelwan.
Cauchemar also wrote and shot three sci-fi short movies, Dedans le monstre, Ordalie and Déchirures.
The short story Valeurs can be found in the anthology Dimension Super-Héros 2.
Despite most of their work being dark fantasy, nightmarish science-fiction or full-blown horror, Cauchemar describes themselves as "a sweet little fairy here to make your dream come true".
