Khione

-Besides being an ambassador, is also an extremely talented mage
-Likes cats, and owns quite a few. Her familiar also takes the form of a cat, most of the time. Zethes knows her weakness. Zethes takes big advantage of her weakness.
-Is basically always tired and in need of coffee because sleep is for the weak, and she is not weak (also because she's a workaholic)
-Coworkers continuously have to remind her to go home, and her family has to remind her to sleep.
-From a young age, her parents had high expectations of her. She had a very strong natural talent for magic. Everything she did was watched closely.
-Behind her back jealous people would backtalk her while others would try to get close to her to find weaknesses to exploit
-Recognizing the toxicity of the environment around her, she finally ran away hoping to find a place where both her talent and hard work would be recognized and appreciated, rather than taken advantage of
-Fell in love with a dragon here, and they eventually got married.
-Now she's an ambassador and proud mother of 2. She literally won't stop showing off her kids and bragging about them; look at her, I'm so proud of her.
-Not based on an OC, but I love her regardless.
