About
The Dark Kingdom is an evil organization which operated on Earth through an alternate, dark dimension where its driving power, Queen Metaria, was sealed. It comprises of the Shitennou and foot soldiers called Youma's. In the past, the Dark Kingdom organised a successful revolution against the Moon Kingdom, but its victory was cut short when Princess Serenity destroyed both the Moon and the Earth. In the present, the Kingdom's goal was to awaken and control Queen Metalia so that their leader, Queen Beryl, could rule the Earth, ideally at Prince Endymion's side, and to avoid the destruction of the planet at the hands of Serenity's reincarnation.
