Ok so I know I haven't updated my other story in a long time, so I will try and get to it as soon as I can and other than that I've been reading more Harry Potter fanfiction so I will probably focus on this more.
Basic premise is Harry is the older brother of the girl-who-lived and it's his life from fourth year on, his fourth year will be her first, and they will get along and have a good relationship the only bashing will be of Dumbledore and some of the Weasleys and probably Snape, sorry im just not a huge fan of Ron or Ginny or Molly the others should be relatively safe. As for Dumbledore, well there needs to be some antagonist besides Voldemort and I don't like Snape, also the scar will not be a Horcrux later on I just don't see a need for it to be.
Lily is alive she was not home neither was Harry when Voldy attacked, James however is dead he sacrificed himself for his daughter.
This is just the prologue and it details the start of the Potter family more than anything else, the chapter after this will be Diagon Alley at the start of Harry's fourth year and his sister's first. I'm going to make this a Harry/Susan story, she will be his age.
Again I'll try and update my other story soon.
Prologue:
Long ago in an age before the founding of Hogwarts great mythical beasts roamed across the globe in search of magically saturated areas where they would feed off of both the ambient magic and the magical inhabitants of the area.
The greatest of these beasts was a Hydra so massive it made mountain look like molehills, with nine gigantic heads each with its own magical strength or power.
When the Hydra began to attack the area that would one day become the grounds of Hogwarts School of Witchcraft and Wizardry by carving a path through the mountains from the sea. To fight the beast eight magical nobles and a magical pot maker banded together to save their homes and vanquish the beast.
When the nine who set out to destroy the beast finally got to their destination each took their own head to defeat.
Two of the nobles were at war with one another and so in order to be as far away from each other as possible they both fought with the outer most heads. Ezekiel Slytherin and Darius Gryffindor both destroyed their respective heads, with Slytherin destroying one that spat acid and venom from its mouth while Gryffindor's head spewed fire. Once both were defeated both nobles took the magical essence of their foe and added it to their own enhancing their power with the abilities of their respective head.
Two witches dealt with the next two heads. With Hera Hufflepuff destroying the head that manipulated nature and plant life to attack, while Athena Ravenclaw defeated the head that would attack the mind either through direct probing attacks or with illusions. Like Gryffindor and Slytherin both witches took the powers of their heads as their own.
The next to heads were felled by Octavius Peverell and Antioch Black. Octavius destroyed the head that had the ability to vanish and hide, while Black killed the head that had the ability to shield and ward itself against attacks. Like the others before them each took the power of their respective head as their own adding to their prowess.
The two heads next to the center were killed by Alexus Bones and Augustus Longbottom, with Bones gaining power over restricting and identification magics from her kill, and Longbottom gaining magic that would strengthen the body and bolster the spirit.
The final, center, head was slain by the pot maker who used his ability to create and change to build and form a prison around the head even as it fired bolts of pure magic from its mouth to destroy it. Eventually the pot maker trapped the final head before crushing it inside the prison the pot maker has created. As the pot maker absorbed the essence of the final head gaining the ability to destroy, what was left of the body disintegrated leaving only the large black pearl like heart behind, the pot maker encased the heart in a ball of earth so that no one could summon the beast again.
The pot maker gained nobility or his deeds that day and the Potter family was born.
Over time some of the families grew and changed while some disappeared. The Potters and Peveralls inter married and eventually the Peveralls disappeared. The Slytherin, Gryffindor, Hufflepuff, and Ravenclaw lines all vanished after Salazar, Godric, Helga, and Rowena built their school on the site of their ancestor's battle either changing their names to fade into obscurity or dying out. Now only the Potter, Black, Bones, and Longbottom families remain and though their ancestor's battle may have faded into legend, the deeds of those families since have not.
Lily Potter sighed as she closed the story book she had been reading to her children who were sleeping curled up in her bed.
Her four year old son Harry and one year old daughter Jade, the newly named girl-who-lived. Lily sighed again as she remembered that night. She had taken Harry to see his friend Susan Bones and to catch up with Susan's Aunt Amelia when the house had been attacked. James had done all he could to defend Jade eventually sacrificing his life for her. She had found Jade crying with a small lightning bolt cut just below her left eye. The small scar was the only proof that Voldemort's curse had rebounded. Being a curse breaker Lily immediately made sure no dark magic was attached to the scar, and was relieved when she found none when Albus Dumbledore arrived.
Dumbledore, a man Lily used to revere was now cursed every time he entered her thoughts, he had been unpleasantly surprised when he found out she along with Harry was alive, especially since he seemed to want to take Jade somewhere.
Lily sighed again as she climbed into bed with her kids once again cursing the name Albus Dumbledore for coming up with Jade's new title, and all the trouble it would bring in the years to come.
End
Ok well that's the prologue I know its short but it is just the prologue.
As for the powers each family got as im sure ill get questions, I gave them what they got based on what I inferred from my knowledge about them. Slytherin had an affinity for snakes and a lot of snakes are venomous so he got venom/acid which will eventually lead to a kinship with and over time parseltongue. Gryffindor was known as a hot head so fire. Hufflepuff I don't know much about so since sprout teaches herbology I just went with plants and nature, Ravenclaw was really smart so mind magic and illusions seemed like a good fit.
As for the others well the only peverall to escape death was ignotus with his cloak so I went with concealment and hiding, for the black's sirius' grandfather/dad was an extremely accomplished warder so they got warding talents. Amelia bones is the head of the DMLE so she gets things to help capture and identify people. Neville at the end of deathly hallows shows incredible strength of body and spirit so the longbottom's got those powers.
As for the Potters james was said to be unmatched at transfiguration and well a potter does make pots so the initial create and change power fits, and since I gave they final head the opposite of that they are also avid destroyers. Im going to be using a family magic system here in addition to the cannon magic system, so that's part of why I explained this.
Ill try and get this and my other story updated soon.
