As the young captain of the Obsidian, a mercenary troop that offers its military talents, your responsibility is immense: you must take the best decisions for yourself and your troops.
Employed by the King of Hauora, earn the respect of your three corps, analyze the battlefields to adopt the right strategies, listen to the advice of your lieutenants, and mount your horse. Make the right choices, because you are the hero!
L'Obsidienne is a comic combined with a game, one title in a series subtitled "The comic in which you are the hero". You embody a character in a immersive story in which your choices guide your progress. In general, gameplay consists in following the comic's panels — which contain clues, riddles and traps — and making choices about where to go and what to do, while using your visual perception to collect clues and be smart enough to resolve the riddles. As in any game, you can lose — sometimes really badly!
