Hi, firstly thank you for starting to read this, I am going to aim to update this once a week. This story is going to start in the harry potter universe with very few, if any mentions of the Marvel Cinematic universe for the first few chapters and then it will become more of a crossover. Secondly, I don't own Harry Potter or any of the Marvel Cinematic Universe.
I'm Dahlia Lilian Belladonna Potter, I was born 10 seconds before my brother Harry James potter who was actually born seven seconds into August the first whilst I was born as July (the seventh month) died. Unfortunately, the nurses didn't tell my parents this as they're watches where a minute out, so they believed that Harry was born in the same day as me. Now I'm sure you're all wondering why is that such a bad thing? Well, a few months before I was born a prophecy was made.
"The one with the power to defeat the dark lord approaches, born to those who have thrice defied him, the child will have power that the world knows not, the one with the power to defeat the darn lord approaches, born as the seventh month dies."
The prophecy could have applied to three children me, harry and our god-brother Neville Longbottom, despite him being born on the 30th not the 31st of July. Lord Voldemort decided that he would attack the potters and send death eaters to deal with the Longbottoms. He attacked and my parents were stunned before he walked over to my crib and cast the killing curse. The curse hit my forehead and rebounded, it killed the dark lord, but part of his soul latched onto mine and fractured it in the process, my soul already dealing with surviving the killing curse shattered into four pieces, three of which were dispersed across time.
The first piece ended up 2000 years ago in the legendary kingdom of Camelot. The second piece ended up 1000 years ago in front of a great castle in Scotland. The third piece ended up 7 years ago underneath a tree blossoming golden apples. The final piece remained as Dahlia Potter, lying in the ruins of her and her twin's nursery. Thus, starting to fulfil an ancient prophecy as old as the first witches and wizards to walk the earth.
'The saviour of magic will prevail and save magic for all eternity. Magics chosen will endure the trials of time in four lives, she will learn all there is about magic, she will embrace both the dark and the light, the one with the power to save us all will be born when magic is succumbing to its death and will revive the great lady magic to her power and save us all. She will love the light and dark and bring revolution to the world and be loved by few but respected by all' so as my soul spread across time the first prophecy was completed and the second prophecy begun.
