The Dark Magic Plague

In the small country of Crystopia, the many villages lived in peace, but then came a dark evil. Magic had always existed in the world, and dark magic was only ever found through cursed objects... until a man appeared. A man who spread darkness wherever he went, simply for his own pleasure. That's when they appeared, Magic users who became Dark Magic Slayers. Due to this evil man's deeds, magic users were hated and feared, so they must fight in the shadows to protect the innocent. For centuries good and evil battled for dominance, but to no avail. They were at a standstill and the evil man went into hiding. Only in recent years has the evil began spreading once more.
