Edenian was located at the bottom of deep sea. There are numerous reason for this. First, the Edenian was envied by the people from the other region due to their longevity and preserved (some of them even eternal) youth. To regain their youthness and immortality, people have to kill them and drink their blood. Many Edenian already fall victim to this. Second, there are a lot of mermaids who live at Edenian sea. Afraid that human will massively catch the mermais, the King decided to bring them to the seafloor along with the region. Death Buster is also the major reason why the Edenian have to fell into the seafloor. There are barriers that surrounded the Edenia region to prevent the enemies to come in. Also, when the Edenia are relocated on the sea, the barriers hold the water from flowing in so the region won't flooded.
