A long time ago, there were two worlds. One was inhabited by witches and wizards, and the other by mortals—humans without power, until a portal between the worlds opened. Just minutes after opening, it closed again, and all that was inside had to stay there for the next thirty years until the cycle repeated itself.
According to legend, every thirty years the moon crossed over the Sanji Star causing the portal to appear. With little time to spare, evil and goodness from the wizard and witches realm escaped into the mortal world, unveiling the power that was within it, in search of beauty, health, and youth.
For centuries, all living mortals and immortals have been in search of “The Fountain of Youth”: a fountain to beautify whosoever drinks from it; to heal those with deadly sicknesses; to change something into something it once was; to make one look younger. It can even bring the dead back to life. The fountain can be used for many things, but first, the magical key must be found; it unlocks the chamber of flowing waters known to be linked to the fountain. The locations of the fountain and the key are unknown. According to legend, they lie somewhere in the mortal world, in the darkness of a forbidden forest.
