Join the Dark

a world that has magic uses that follow a rule system. The magic can be learned, or it is natural for some. It has a royal government system for a long time, possibly until the future. It starts as a low technology society, though with electricity figured out after the magic group is accepted. There is a group of "High Mages" who are the magic users sanctioned by the king and queen. Everyone else with magic use is banned from the kingdom or even hunted. The magic wielders discovered a form of "electricity" (which might be derived from natural energy in the surrounding area, meaning it's more effective the closer to an energy source it is: plants, nature, storms, animals, people)
