There are some who would argue every single member of the sprite communities (imps and pixies) are non-conformists given they have a long history of fighting for the sake of fighting and creating havoc as a result amongst their own and those unfortunate enough to live anywhere near by. Wizards, in particular, have been known from time to time to eliminate sprites when they've been aggravating enough in a deliberate bid to bring the remaining into line. In fairness it works but usually only for a few months. Then the wizards eliminate more, the havoc subsides for a bit and so on. The Queen and her ancestors have done what they can to rein the wilder sprite elements in but accept this wildness is part of their characteristics so will not go altogether.
Queen Gwendolyn, mutual great-grandmother to the Queen and Eileen, is the ultimate royal rebel. Gwendolyn married many times, including to humans, whom she brought back to the fairy world, much to the disgust of her subjects. They didn't stay long. Public protests, sustained and turning violent, led to the monarch dumping her human spouses. They weren't that sorry to go home. Her worst marriage was to a powerful wizard, by whom she had a child. She abandoned the pair of them and they both turned to the dark side. The Witch and her family come from that line and continue to cause the Kingdom grief. Eileen has some sympathy with the Witch, knowing the history, but this puts the fairy godmother out on a limb since the rest of the realm only sees the Witch's destructive sprees.
Eileen did manage to achieve a unique rebel feat in that she defected to marry a mere human and go and live on Earth with him though the Queen still plans to get Eileen, and daughter Jenny, back. (The Queen has realized she can used Jenny to blackmail Eileen and that there is no way Eileen will go back to her old world without her child). Eileen has also questioned magical power abuses in a way that would get others killed, relying on her royal status and the fact the Queen has no direct heir to save her. So far that approach has worked.
So the realm has had its fair share of non-conformists with Gwendolyn and Eileen being the most renowned (though whether this was a category you'd want to be renowned in is open to debate).
