Snape pov:

Snape knew the Potter boy was comming to Hogwarts this year, but he could not see the brat.

But something else caugth his eyes,a girl, an exact replica of Lily the day they went to Hogwarts for the first time, but Lily was dead, and she didn't get a daughter either, but a son with raven black hair, said to look like a clone of his father, James Potter. What had happened to Harry Potter? Who was this girl? Was this girl related to Lily? How did she look so alike Lily? How did it look like like she had the same level of confidence like Lily? He continued to ask hinself these questions, comparing the girl to Lily, until he was brougth out of his musings by McGonnagall calling the girl's name: 'Evans, Lily!'

Lily Cosette Harrietta Evans pov:

Wow, this is so big, like the space of the livingroom in the manor just a thousand times bigger! Well I'll bether go and get sorted, hope I get in a good house. I stepped up to the stool, and I sat on it and let the hat have a look into my head.

'What do we have here? An heiress! You are both cunning, abisious and clever, you posess a good mind, and a hunger, a will so strong wanting to gain power, yes you will do well in' 'Slytherin!' the sorting hat yelled loudly with respect and pride in it's voise.

Not bad, not bad at all.

I went over to the Slytherin table and seated myself before anyone had time to bother me on that. A girl, Pansy Parkingson came over to me after beeing sorted herself.

-If you are a dirty mudblood, or a know-it-all-ravenclaw, you are doomed to seven long years of lonleyness and if you aren't, you still had to serve me as leader of the first-year Slytherin girls, and any objection is to be punished, Parkingson told me.

-Then I bether tell you a little story of the name Evans's orgin; Once upon a time, more than a thousand years ago there was two men named Salazar Slytherin and Godric Griffindor, and two women named Rowena Ravenclaw and Helga Hufflepuff. They shared the same dream, to create a school, (blah blah bla, yes we all know the intro) then Griffindor imperios Slytherin to deny sholarship to muggleborns, to make himself look bether, Slytherin escapes the imperio, but can't repair the damage done so he adds a secret chamber to Hogwarts, that only his heirs can open, thus exsplains why nobody's found it, then he left Hogwarts to never return, even though he was the founder owning the school,he was a fantastic architecht then he got married to the wizarding king's sister, Eve Emrys who died during childbirth of twins, then he made up a new spell to protect his first-born child and the children of this child, a girl named Cosette. The second-born, a boy, he oblyously didn't care about, because one night when being drunk, he transfigured his only son into a half-monkey and sold him off to the Gaunts, who are known to be related to Slytherin, they still brag about it. Well, when Cosette was old enough to leave her home, Slytherin had come up with a new name for her: Cosette Lillium Evans, short for Eve and Salazar. Slytherin also made sure of that none was to harm Cosette, or any of her magical heirs, so the heir or heiress would survive any attemt to kill her or him. Also the first-born, if magical must keep her or his last name as Evans, even if it is her/his mothers maiden name. We also get all the knowlege and powers of our ansestors since the time of Salazar Slytherin, but it will be unlocked until we gain a consious mind and can remember things. We can neither use the special powerful powers while in the heat of the fight, or unwillingly, so don't try to imperio me, it won't work.

If you want it to go on and find out more about Lily, and what happened to the boy who lived and disappeared you will have to wait for the next chapters. Will try not to make a god out of Lily and yes boywholived has something to do with her. She won't be queen of all slytherins. Not decided pairing vote for anyone but the Weasleys, can be slash though it will be challenging since I've never done a slash fic before. Yes Myddrin Emrys is related to Eve, he's her great grandfater, but it will probably not be so important, but no the plot is not done.
