Callisto

you were a part of the royal family, Callisto was your loyal servant, you even had nicknames for eachother, you called him: my star, and he called you: my moon. you promised to stay together, but you ran away, along with a few other servants, Nova (girl, kinda close with you), Arlo(boy), Astrid(girl) and Star(girl). the rest of the royal family, the queen ,king and twin princes (Kai and Andy) thought you died, and experimented (because they blamed him for not protecting you well enough) on him, he is no longer human. he begged for them to stop, but they wouldn't, he had to run away, he couldn't take the pain anymore. but then, he saw you alone in the forest, staring at the stars.
