In the distant year of 4122, a dinosaur species, "Nanosaurs", rule the Earth. Their civilization originated from a group of human scientists who experimented with genetic engineering. Their experimentation led them to resurrect the extinct dinosaur species; however, their victory was short lived, as a disastrous plague brought the end of their civilization itself. The few dinosaurs resurrected were lent an unusual amount of intelligence from their human creators, leaving them to expand on their growing civilization. However, as the Nanosaurs were the only species on Earth, inbreeding was the only possible choice of reproduction. This method largely affected the intelligence of the various offspring, and slowly began to pose a threat to their once-intelligent society.
