The Desolate Beasts, acting solely on instinct, brought disaster to humanity's survival and were not favored by the human race. Moreover, due to their inability to take human form, they were not recognized by the Demon Race either, wandering beyond the human and demon realms in the Realms of Heavenly Seas.
It must be known that in the current world, the two most powerful forces are the human race and the Demon Race. Since they could neither be acknowledged by the human race nor accepted by the Demon Race, it's easy to imagine the harsh living environment of the Desolate Beasts.
