Metaphysical / Paranormal event
In the continent of Kirinokuni, the lands have been completely obscured and covered by an ashen mist that prevents creatures' from entry into the land. Those who chose to leave, cannot return either and are branded as wanders by the natives. Little is known why this event occurred, even to the natives. Rumors say that this was a blessing by the divinity that governs the land to protect from the harms of the world.
