This is Opaline's reformation version of the Roots of evil. Opaline had stealed all of the ponies, including Sunny and her friends,Plus Misty cuite marks to gain in Power. Opaline,who is now the fire alicorn had feel regret for doing this but she had to do this because these evil voices in her head wants her too.

Sunny:You may take away my cutie mark but you can't take what makes me,me. Hope. Hope for a better future for all ponies to make their mark.
