I obeyed someone who would never obey me
He also tried to murder me
Though my brother didn't want me to do
My mind said " Your family will be proud of you"
Though I didn't like the work at the end
And I knew I was to be behead
I killed a piece of him
EASY
So far no Houses doesn't have any points, so answer the riddle with your house and hogwarts name.
Good Luck!
