"In a time 20050 years in the future, our Earth has become a world of dust and frigidness. It has been 4 millennium since World War 5, where the purging of wolves was rewarded with big money. What they didn't expect, was the wolves to fight back.
The humans discovered two intelligent specie during the War, the Lycan and the Wolflin. Hidden away in the mountains where no sane man would go, they had divided lands.
Though a similar specie, the predators did not get along. Only when the threat of men materialized did the two join forces for the coming war. And boy, they were a force to be reckoned with. The population of both wolf and man decreased and decreased, until a treaty was created. The wolves would own half of the habitable land, and the humans the other.
As the years passed, a new specie arose. A hybrid between Lycans and Wolfins. So powerful, their bodies cannot survive the first shift. The Origin Family, leaders of both specie, banned the birth of this hybrid. Ensuring this new law, the Lycans and Wolfins went back to their old ways. All Hyrbids were captured and killed, and their threat was terminated.
Or so they thought.
