Exodromos is a prequel of 'Planisphaerium'; the story tells about futuristic science concepts and chaotic visions of the last human left in cosmos, Krighsu. These are particularly in relation to the awakening of the "Chrym" once the last humans of the year 8K, called the Terrax, dissapeared, and the known universe was absorbed by a quantum wormhole in a inverted multi-vectorial reionization. Krighsu, will travel through xenoverses to found a new world with the human seed. The paradox: Krighsu is not the habitual human you all know.
