Mutants: due to he vast experimenting with radium, accidents happened. Deadly, damage, illness and in rarely mutation. Altho mutation sometimes isn't noticable even by the person himself or the effects are hidden. In some societies these mutants are shunned and slightly feared. In some very rare occasions mutation occured that had an efect on the persons mana "abilities" that magi need years to develop, but most mutations are from the physical kind, some gave special abilities as enhanced vision.
If you like my idea, my char will be one of those don't know it mutants and will discover it trough the story.
