Lucifer and their fire

Throughout Fiora, only a percentage have the perfect balance, the flow of magic energy around them and inside them in perfect sync. These few become part of guilds, helping the ordinary people with things they can't do, such as be ridding the monsters that go bump in the night. These wizards would never harm the citizens, would never destroy anything they spent time building without fixing thing. Unfortunately, if there is the good, there is the bad. Much like there is the most powerful heroes, there is the most powerful villains. The most evil, scared of, villains are a couple, their love shadowing the land. Their names strike towns into shutdowns, their evil doings would fill a grand library; Mavis and Zeref. But they are another story, this tale goes to their successors; Natsu Dragneel and Lucy Heartfilia.
