They were assassinated by [link] when Fluttershy was 7, she was present during it, and it might have caused her submissive nature. She was adopted by <Insert the canon parents of fluttershy when they are shown.
On their actual personalities:
Sunburst was a very overprotective father, and was very close with Celestia, and would tell Fluttershy stories about the princess and how she felt, not just what people thought of her. He enjoyed making people happy, and would tell fun stories so people would laugh.
Tulip was a kind and helpful nurse, who originally was a nurse, during the war, she became involved in diplomacy. She was Nurse Redhearts sister.
I'll upload the one without the ghostly glow. EDIT: Here [link]
Feel free to use this HC, with credit. Any part, really, if you don't like the other part, the designs as Fluttershy's parents. ONLY HER PARENTS.
