Charmcastor is a 16-year-old former villain from Ben 10.
She had been in love with the younger spellcaster Gwen Tennyson ever since they first met. At first she was upset to find out that she didn't know Gwen was a lesbian until she already found a girlfriend, but fortunately they were both willing to share. And they spent a few weeks living in a cabin in the mountains.
Eventually the cabin start getting cold so they decided to use a transportation spell to go somewhere warmer, and they wound up on a different planet.
