The inspiration for the psychic Gift of Nokwahl, the main character in my first novel ("I'll Tell You No Lies") and of the second one I'm writing, was from a Star Trek episode. It was an episode where someone (I think it was Geordi) was being tortured and having his brain reprogrammed by the Romulans, and one of the Romulan torturers was identified as being a reverse empath... having the ability to make someone feel anything the reverse empath wanted to them to feel.
I was immediately taken by this idea, and decided to give this power to Nokwahl. And considering her personal history, I doubt I could have thought of a Gift more suited to her. And seeing as she's somewhat of a superhero, and considering that many superheros are ambivalent about their powers, her Gift of reverse empathy - and the fact that she discovers her Gift on accident, using it accidentally on an innocent - it is so perfect for her!
