Artemis Joule

The daughter of Archemedies and Tyrphia Joule, two very magically inclined parents who had planned their daughters acceptance into wizard's college down to the date. Except the child had no skill with spells, magic, or even potions. When they began showing signs of being a teifling they shipped her off to Archemedies' brother Regulus, figuring he would know what to do with her if she didn't have any magical prowness. 
Artemis was only twelve years old and living with her Uncle who had been living on his own in his sanctuary in Liste. She met a few of his other pupils at the sanctuary, mostly in passing including a changelling storm sorcerer named Desi Ignar, who she took a liking to and tried to run away to their tower out in the Land of No Kings, but was returned to her Uncle.
She was set on getting some magical ability enough that she began to research about Levistus, a Devil Prince, thinking maybe that he would be willing to give her the warlock powers she desired. She figured how to reach out to the devil prince, but instead of getting the offer from the prince she gained an audience with Aur Malestro Malovence, a eyrines. 
Why become a warlock when she could be a fury?
Wings! Eternal Life! Magic?!
It all could be hers, all it would cost is the use of her body.
Artemis was overjoyed, but what if someone became suspicious? What if someone stopped or changed them back before she was ready?
She hatched her own plan, a little bit of insurance on making sure no one would ever try and covert them back.
Artemis tried to reach her parents but they refused to speak to her, even Regulus attempted to bridge the conversation but they had decided that if their daughter wasn't going to be a spell caster like them then she wasn't worth keeping around. 
Finding this out on her sixteenth birthday, she turned to the contract that Aur had given her and signed it in anger. 
Not knowing what was next, she felt herself being tugged out of their flesh and across the planes and space in an instant. The world went black around them and the smell of petrichor candle leaving only to be replaced with that of the infernal burning plane.
