A Better Idea
When a world entered a state of Dimensional Descent and their Metamorphosis began, a World Spirit would be born. Upon the birth of the World Spirit, a world would make a bet on a certain group of youths and bless them, allowing them the chance to enter Zones and fight for the right to earn a piece of the World Spirit. Of course, in this case, the World Spirit would be split into four.
On Earth, for whatever reason, the World Spirit was awoken ahead of time and it chose to take on Leonel's mother as its host. As such, it never split into four.
Of course, the reason for the usual choice of the World Spirit was quite obvious. It wanted to select a group of talented youths to fight for hegemony over the budding world. These four youths would usually establish families or organizations that would carry a great deal of influence through the history of the world.
