He also has piercing grey eyes, just like his grandfather. Despite his family's dark legacy, the boy is determined to forge his own path and use his magical abilities for good.

Author's notes: So this story will have slow updates as this idea was stuck in my head for a while, and I can't really find a fanfiction with this idea so I'm making one. You can even copy my idea since I don't know if I will put an end to this story. I will apologize in advance if there are grammar mistakes because English is my second language. I don't own any of J.K. Rowling's works, except my SI-OC character.
