The corruption of the supposed saviour (Harry Potter)

The start

Yns pov: 'I know they are after me because I stole the Time-Turner I did the only logical thing and I was able to arrive at the Potters undetected I heard the screams  and then it was quite I knew my father was dead but I realised if I corrupted Harry from the start I would be able to save my father and become the Augury  I saw haggard arrive with Sirius looking like he'd seen a ghost I couldn't hear what they were saying but I figured if I went to the Dursleys I could raise him and make him believe that dumbuldor is the bad guy.
~~ Time skip 5 years ~~
... " y/n why do auntie and uncle hate me"  y/n "Harry that's because they're muggles and they hate Magic and you are the most powerful wizard to ever be born"  Harry runs  to  you and gives you the biggest hug ever. Y/n explains everything to Harry in her perspective and he believes everything well, who wouldn't when you've been cut off from the world, you're supposed to protect and letting him grow up with people who hate him and then someone who you've seen since the beginning who cares for you tells you everything they want you to know and the world they want you to believe in because in the end, you will believe them because they are the ones who took care of you. It's very easy to corrupt a five-year-old boy they should've been careful, the boy that was supposed to save the world will become the reason they fall
~~ Time skip 3 years ~~
Harry " y/n l Can't take it, there horrible, treating me like a slave. Can we leave and go somewhere?" y/n " of course harry how about I bring you somewhere that belongs to my family"
~~ at the bank~~
" hi I would like access to my family vault" gremlin " Do you have your key?" Y/n " no but I would happily do a blood test to prove it oh and also my little brother would like to make a withdrawal the blood test as the same method" "Right this way"
~~ after the blood test ~~
Goblin " you kids have access to the black family vault, slithering's vault the Potter vault, the Gryffindor vault, and a few other vaults, but these are the most important ones I'll give you a list of all of the votes you have access to" y/n " thank you you're so kind just don't tell anyone that we've been here alright"
~~At the vaults~~
" you can get whatever you need alright I'll just be getting a few things" I know the location of the black family mansion is here I also have to get the invisibility cloak and the resurrection stone. This world will be in shambles. I can't wait.
~~at the black Mansion,3 years later~~
Harry " oh my God, it's here it's here. It's here my acceptance letter" y/n " well open it Harry"  " HOGWARTS SCHOOL OF WITCHCRAFT AND WIZARDRY
