A comic by kurapika

Due to human negligence the world as we know it has ended and been reborn. The animal spirits that guide men gave them the forms of animals so that they would be able to survive in this new wilderness. Though now carrying the form of beasts, men has not forgotten the place they once had, as an existence greater than just what nature wanted of them, an existence above all.

Those that worked to regain their humanity are known as domestics, while those who wished to follow the roles the spirits had given them are known as wilds. Both groups grew arrogant and hateful of each other, the wilds saw the domestics as selfish monsters, for they were returning to the ways that had once destroyed the world, while the domestics saw the wilds as primitive beings afraid of progress, being no better than wild animals.

The raven and the wolf spirits grew tired of the destruction and fighting, and sided with the wilds in their ideals, the domestics only capable of further destroying nature. In their anger they marked a tribe of wilds with a curse, they being removed from the sacred circle of life, unable to hunt or grow their own food, their souls never able to move on while their bodies are unable to return to the earth when they died. The curse upon them only broken once the domestics are gone once and for all. The cursed tribe is now known to all by the name of the spirits who cursed them. ‘Raven Wolf’
