********
A certain uninhabited island. There is a barrier around it, and it is monitored 24 hours a day. If the monsters living on this island landed in a remote area, it wouldn't be a tragedy.
Some monsters land on the island like that. One of the few monsters on this island allowed to leave the barrier. They probably hunted around this uninhabited island and brought back a great white whale to the herd.
This is the land of the end. An island where swords and demons fought for 10 days and became the world's scariest danger zone. Primitive griffins live in groups on such islands.
The Primordial Griffin used to live a normal life in this world, but because of its strength it was often challenged by humans, and its numbers had drastically decreased over the years.
