The world went down 200 years ago. The continents are radioactively contaminated and biologically infested. Mutants now populate the more than two-thirds destroyed surface of the planet. Obscure creatures' rule with brutal sanctions and unnatural-looking technology over the rest of humanity. Two mutant families live on the edge of a desert area in underground caves. To the east, on the other side of the mountain, there is the power center of Muhlork. These are the adventures of the young Marvin Greybond through space and time on the way to his true destiny.
