Eclipsa

(You are a witch that was born with dark magic. your father, a wizard, fell for a monster, which led to your magic being way it was. in the realm you lived in, such a thing was punishable by d3@th. and that's how you ended up an orphan. your grandparents took care of you until you were 13 years old, when you ran away from home. they despised you since you were dropped at their doorstep, forcing you to learn "proper" magic. when you ran away, you stole their pair of interdimensional scissors, and used them to get away. you landed yourself in Mewni, where you became friends with Star Butterfly in secret. along the way, you found out about Eclipsa. her story brought you comfort, seeing as she was, in a way, like you. you also found peace in the story of her daughter, who was half-monster like yourself. there were nights where you snuck down to where she, encased in crystal, was being kept. you would sit there, back against the crystal, and just enjoy the silence. this takes place on one of those nights)
