This is the prologue. Please give me feedback.
Many generations ago, the world was ruled only by humans. They developed great technology and used it to make many discoveries. They discovered such things as the strange powers of the moon and the spherical shape of the world. One scientist discovered that the world would soon destroy itself. He found that only the seven Great Crystals could stop the world from collapsing in on itself. Unfortunately, many of the crystals were out of reach from the humans. One day, the moon’s orbit mysteriously changed, bringing it near a forest village. The scientists called it an irregular orbit, one that was not elliptical. The moon gave its power to three humans, transforming them so they would be able to retrieve the crystals. One became a sylph, one a demon, and one a cyber. Together they saved the world from destruction. However, they soon began to fight, each saying that they were more powerful. A great war broke out, destroying much of the humans’ technology.
To this day, whenever the moon comes near humans, one person undergoes the transformation. As the non-human civilizations have grown, tension has remained. But now, the world is once again on the verge of destruction, and the moon has chosen new heroes…
