Alma Torran was once a world ruled by a powerful magician, Solomon. He was a well loved and respected king, and three Magis supported him. At some point, after the betrayal of one of his Magis, a war exploded where the Magicians and Goi fought each other. They were attacked by the Medium, its Black Djinn and Al-Thamen. In order to fight against them, Solomon's 72 Household Members became Djinn and attacked them one after another.
In the end, a lot of the people of Alma Torran were left dead. Solomon created a new world, the actual world where the humans live, and the survivors of Alma Torran were settled there.
