To change the future to better one

To the past

It's Sunday , October 31 1976, the students of Hogwarts sitting and eating their breakfast. A certain 6 th year griffindor is watching a red haired  griffindor ." I am telling you four ,I am going to marry her ! I can just tell we are perfect for each other" his long haired brother in all but blood and dark brown haired  friend snorts " yeah ,sure you are prongs." Prongs looks at them in offence and betrayal ," padfoot ,kings how could you?!moony ! Padfoot and kings isn't supporting me " moony rolled his eyes " why do I put up with you guys." Prongs ,kings and padfoot responded " because you love us" " eh"

Meanwhile a certain Slytherin is looking envious of the friendship between prong ,kings and padfoot.

After a while kings is looking at a certain dark hair beauty in ravenclaw and prong , padfoot saw this started to tease him and he said " oh fuck off" moony is shaking his head .

Just then the door of great hall has opened , revealing the Blacks, Potters , delacours with Young girl,the Weasley with three young kids, the tonks with their little girl,alastor " mad eye" moody , Malfoys and lestranges.

Dumbledore stands," welcome guests , may I enquire as to why you are here?". Orion steps forward " we all recived a notes telling us to be here at this time . They were anonymously singed"

A small table with eight thin cases on it,a letter appear out of nowhere, a letter, floating in front of Albus.

" Hello professor Dumbledore,

My name is sahithi and I am writing to you from 2004.

Every one perks at the thought of someone from future writing to Dumbledore

"With these letter ,you should have also eight movies. This movies are about Harry's life , and we are hoping that by sending these back for you to watch, will change the course of time  for the better"

Every one frowns ' what could have possibly happened in Harry's life?'.

" Myself and few friends  will  join you  and your guests who I sent notes to - tomorrow before you start to watch the movies. Untill then mischief managed "

" Signed
S.V.W , H.J.P , R.B.W , H.J.G , J.A.D , G.M.W , N.F.L, L.P.L , D.L.M"

The Marauders share a looks, that phrase only being familiar to them ." Do you think they our kids?" Moony nods," I would think so .....we came up with that phrase, and we couldn't tell any one but our kids"

Walburga sighs irritatedly" we could have come here tomorrow, why is it necessary for us to come tonight?" A note appears in front of her " because I said so- sahithi" Sirius snorts, liking this sahithi girl already . Dumbledore address the guest " you all may stay in our rooms reserved for guests . After breakfast Tomorrow,we will setup the great hall to wellcome our guests from the future"

-Time skip to the next morning-

After breakfast, Dumbledore waves his wand and the great hall turns into a comfortable space for everyone, a ginormous
Screen against the wall where usually the teachers tall sits. Everyone takes their seats and wait for their guests from the future.soon a loud woosh sound is Heard outside the great hall,the doors opening reveal nine witches and wizards , who all have hoods  of their robes. Every one perks up and intrested in the mysterious visitors.
They all walk to Dumbledore who stand infront of ginormous screen." Hello I assume you all are our guests from the future " they all nod, refraining from talking, adding to dramatics of new commers ." Would you all mind introducing yourselfs and then we can start the movie"

The nine people turned to face the  audience one of them letting their hood down as they start introduction." Hello my name is Hermione jena Granger . I am 24 years old and I am in griffindor and i am muggleborn." The pureblood who believe in blood supremacy looking at her disgusted." You call all scowl and snarl all you want . I don't care what your opinions on me is , so your insults do not effect me."
