Meet Raven Mist :3
 
Originally a feared and powerful dark witch and potion master, she used to terrorize the surrounding villages by her castle, wanting the population to fear her and serve her. However, this changed one day as one of her potions was more powerful then she expected, causing it to completely destroy the surrounding land, forcing everyone to flee, now homeless. Seeing the result of her actions, she felt ashamed of herself, running away and vowing to start a new life.
 
Years later and she ends up becoming interested in Black Metal bands, and soon after training herself, she has become the singer and guitarist for a popular Black Metal band. She remains stoic, and often keeps to herself, not wanting to have anyone learn of her past life.
