Possible Story Characters

So, this might not happen, but these are possible characters for a possible story. I don't own MLP, but I own these characters and their story.

Characters:
Desvarn Jinert Mariscolia (Dez-varn Gin-ert Marr-s-coal-lia)
Breed: Pegasi
Gender: Male
Age: Twenty-One
Coat: White
Mane: Silver
Eyes: Green
Cutie Mark: A broken crown
Talent: It's assumed to be ruling over the kingdom long left broken, or rather, that's the best assumption. It is also suggested that it could mean he would shatter the only peace left in the kingdom.
Family: His father was the past dictator, Desvarn swears that he will not follow his footsteps, although his father had tried to keep peace. His mother was very kind and sweet, she knew Desvarn’s father when they were foals, which is probably the only reason she tolerated him. His mother died when Desvarn was five, his father died when he was nineteen. He has a little sister named Salverna, whom he would protect with his life.

Salverna Calisen Mariscolia (Sal-ver-na Kale-son Marr-s-coal-lia)
Breed: Pegasi
Gender: Female
Age: Sixteen
Coat: Black
Mane: Amber
Eyes: Blue
Cutie Mark: A paintbrush
Talent: All things to do with art. Painting, sketching, sewing, sculpting, dancing, singing, and many more things.
Family: She never knew her mother, as she died when Salverna was born. Her father was distant, and she was raised mainly by her brother and the maids. She is incredibly naïve and because of this, she doesn't take part in ruling the kingdom, nor is she given information about it.
