LOL! She was just a b!tch with magic tears. I was thinking of the one with the midget who didn't have the mind-control abilities of the other Greek gods on the planet. (Maybe they were Roman. I'm getting old)
The episode was Plato's Stepchildren, I think. They were a band of inter-stellar travellers who admired the world of classical Greece and dedicated themselves to blah, blah, blah...
The psychokinetic power came from the diet on the planet where they settled. The cruel king's name was Parmen. His wife was hot, but a bit into S&M. The little guy, Alexander, was played by the same actor who played archvillian Megalito Lovelace on the Wild Wild West.
One of the songs Alexander was made to sing included lyrics from Aristophanes' The Frogs.
And I never tried to be a Star Trek geek. It just came natural.
