Luna POV
My training was completed since I was eight years old as Mistress Death took me as an apprentice once she sent me back in time.
At nine years old I saved my mother's life from a mishap with a spell.
Once then I claimed the three objects to open the Deathly Hallows as teacher told me to return the cloak as it was harmless back ro the Potters, told me to keep the Resurrection Stone and Elderwand as they are bound to me.
Once then I returned to my timeline where my mother is alive as I'm in my room playing with my family ring.
Mother: Luna, it's almost time to leave for the train, are you ready?
Luna: The Quidditch World Cup was attacked by Death Eaters, I thought me killing Greyback would dull there attempts but I guess not.
Yeah I killed the most ruthless werewolf ever, Fenrir Greyback. He was a nuisance the Ministry allowed free for too long.
Now there's that about me killing him in the Daily Prophet.
Mother: I know sweetheart but Harry needs you, I saw how strong you are, your stronger than Dumbledore, you know Wandless spells of your own design so go help him.
I smiled at mother as saving her was the best idea, should the Death Eaters come they have a safe house prepared.
Luna: Very well, it's time to begin my fourth year then.
I destroyed some of Voldermorts Holcruxes and now Dumbledore knew the Elderwand was in good hands as we made our way to the train station.
