Genius, [ex-]dictator, torturer, mage. Pretty unpleasantly ran a country for five years, disappeared when that was put an end to. Did science, invented a disease cure. Late enough and she's in prison (where she continues doing science).)

(Copying in from old author page:
Villain. Likes being effective especially in interesting situations, doing research involving using her magic, power, and torturing and traumatizing people. She does not aesthetically mind people suffering because someone wants them to (though she’ll totally fight someone causing such if she has reason); she does aesthetically mind people suffering due to incompetence etc.

Can be transported out of being in prison. In that case she will want to get what she can out of what she wants, but will refrain from the torturing. She can thus be very helpful).)
