Arella the Ghosty

Backstory

Arella was a talented (at burning stuff) young witch at Hogwarts. Doing well in her first and second year, her progress was stunted in third year, after being buried in essays. One day, Arella suffocated in a pile of essays and died. Now, Arella enjoys pranking the students and teachers of Hogwarts and setting random things on fire. Just like when she was alive!
