Long ago, when the Earth was still mostly covered in forests, there was magic everywhere. Our planet was so overridden with magic, as well as magical creatures, that it was causing it to crumble. The Earth, could not take the pressure of the ever increasing force of magic, and was nearing extinction. At that point, Tsar Lunar (Man in the Moon) realized that something had to be done about the situation, so he cooked-up a plan to save the planet. Sending messages to all witches, warlocks, and other spell casters, telling them to meet at the North Pole in three days, he set the gears in motion.
After three long days, all the strongest magical creatures were at the Pole, and ready to begin the task given to them. Using all their energy, the ground started shaking, as they slowly began to split the Earth in two. As everyone was doing this, the Man in the Moon started his job of making a large portal, after which, he would send half the planet through.
The Man in the Moon figured, that the only way to stop the growing flow of magic, was to transfer most of it safely away where it could not do damage. The first step, was splitting the Earth in half, and shaping the two halves into separate spheres. Then, placing as many magical beings on the second sphere as he could, only letting certain ones (the least dangerous and most important) stay behind. Finally, the second sphere would be teleported across the Solar System, so it in no way would bring trouble to the Earth again. At least, that is what he thought.
Even after, the other half of the planet was sent away, the Man in the Moon kept a close eye on it through a special mirror he owned. Using the mirror, he could make sure that its unlimited supply of magic could not become to corrupt. At times, there were problems, but they always seemed to solve themselves. However, a great and powerful evil was headed to the planet, and had a devious plan to bend all on it to his will. The planet would now need heroes to protect it, it would need special people to watch over everyone else (especially children), it would need Guardians.
The only thing that remained was the questions: who would these Guardians be? How would they fight this evil? Who would get them together, and most importantly, how would he get to them?
