I do not own harry potter, nor Skylar, I only own Elsa and Gwen. Skylar belongs to my Wattpad friend Skylaris_Anasaki.

Summary: Harry Potter had a sister named Skylaris Potter, or more commonly known as Skylar. She was raised by Mcgonagall. In 1986, when Skylar is four years old, Hogwarts decides to allow her and many other four-year-olds who are especially strong with Magic in as first years.

Chapter 1: The beginning of a Friendship

"Hello Minerva" Snape greeted as he entered Professor McGonagall's office carrying a young girl, with long golden hair and strange Purple eyes. She looked to be no older than Six

"Severus what are you doing here in the summer and who is that child you bring with you barging into my office," McGonagall says as she picks up a young brown haired girl up from the ground she looked about 4

"I need a Hogwarts acceptance letter for Diana Phoenix's daughter. Elsa and I will be spending the rest of the summer here on Hogwarts grounds so she will not get lost when the school year starts" Snape says setting the child down

"I will need to evaluate her first make sure she is prepared for school at such a young age Snivel… I mean Severus" Mcgonagall says

"She is and isn't Skylar starting this year" Snape sneers

"Skylar is a gifted child she has an eidetic memory and has been here since she was 2 months old," Mcgonagall says going back to her letters with Skylar still in her lap

"The Royal Princess is very gifted," Snape says in a low toned voice too where Elsa couldn't hear "I have no doubts she will be just fine, and if you need proof I have spoken with Albus, he will agree of Diana's daughter being admitted early"

"Very well have her report to the stairway in front of the main hall on the first night of school then so she can be properly sorted and housed," Mcgonagall says

"Severus can we go make potions now?" The child, Elsa says

"I would dare her missing out on the sorting, she will make a fine slytherin" Snape says

"You know the rules Severus each and every student must be properly sorted no exceptions" Mcgonagall says looking up from her papers sternly

"And she will be, i have my faith she will be in the same house as her mother. It wouldn't fit for a lovely girl too be in the house that Black was in" Snape sneers

"Minnie the mean man is talking bad about god papa again make him go away" Skylar says hugging onto Mcgonagall

"Sevy, I wanna make potion now?" Elsa says pulling on Severus's cloak

"No Elsa, no potion today" Snape says leaning down too elsa's height

"Learn new spell?" Elsa asks

"Not yet" Snape says

"If that is all you wanted Severus you can leave now me and Skylaris need to finish up getting things ready for the first years

"Come elsa, let's go flying" Snape says taking the girls hand

"Yay! Fly! Fly" Elsa says and snape leads her from Mcgonagall's office

"Can I go flying to Minnie?" Skylar asks

"Of course my dear I will call for madame Hooch and she can go train you for being a chaser on the quidditch team this year" Mcgonagall says sending and owl with a quickly written note on it to Madame Hooch

"Madam Hooch, I have some pre-school year things to do, would you keep an eye on her" Snape says approaching the quidditch pitch seeing Madame hooch headed up towards the castle.

"Um I was just on my way up to see professor Mcgonagall she summoned me but I suppose I could take this young lady with me I think Minerva wants me to train Skylaris up for Quidditch try outs" Madame Hooch says

"I stay here till you get back" Elsa says climbing into the stand "I no go anywhere"

"Thank you" Snape says "Elsa behave and no fighting young Skylar while I am gone"

"Come with me Miss Elsa" Madame Hooch says holding her hand out to Elsa

"Otay" Elsa says skipping after Madame hooch they head up to Professor Mcgonagall's office where Skylar is suited up in her protective gear for Quidditch practice and she grabs her Nimbus 1999 when she sees them come in

"Hi, Madame Hooch ready for training again today?" Skylar says enthusiastically

"Well my dear we have someone else joining us today so why don't we just practice flying today and save quidditch practice for tomorrow" Madame Hooch says

"Sevy teach me quidditch at spinners end, he say my daddy was on the quittch team" Elsa says

"Yes well I would feel better if we just practice flying today" Madame Hooch says

"Otay, Otay" Elsa says happily

"Let's get out there then children you are going to need to be a step ahead of all the other students this year" Madame Hooch says taking Skylar's hand

"I can fly with no hands" Elsa says as she bolts towards the quidditch pitch "COME ON!" She yells behind her

"DO NOT GET ON A BROOM UNTIL I GET THERE AND TELL YOU TO YOUNG LADY" Madame Hooch says "well looks like she is going to be a handful in class huh Skylar"

"Yep" Skylar says rolling her eyes and nodding her head

"WALL!" They hear elsa yell

"Oh dear," Madam Hooch says as she turns the corner and they see elsa getting off the ground having run into the wall

"Walls hurt" Elsa says

"That's why you don't run in the halls you will need to learn all the rules of Hogwarts of you are to succeed" Madame Hooch says

"Severus gave me coffee" Elsa says

"Ok I am officially going to kill him and get Coffee off of your diet" Madame Hooch says

"He never ever gives me coffee" Elsa says

"Then why would he give you it now when you were about to be placed under my care" Madame Hooch says

"I dunno" Elsa says

"Wonderful from now on until Severus comes to collect you, you stay where I can see you young lady" Madame Hooch says

"That's no fun" Elsa pouts "I'm not a little kid"

"Either that or I will bring you back to Severus and report that you have been misbehaving" Madame Hooch says bending down to look Elsa straight in the eyes

"Fine" Elsa pouts

" let's go then this time slower" Madame Hooch says

"Hi my name is Skylaris Potter but you can call me Skylar" Skylar says to Elsa hoping to make a friend

"My name is Phoenix, Elsa Phoenix" Elsa says

" Do you maybe want to be my friend" Skylar asks nervously as she had never had a real friend before

"Sure" Elsa says

"Yay" Skylar says about to go in for a hug but holding back not wanting to break Elsa's boundaries and upset her

"Are we there yet?" Elsa whines as they were nearing the doors

" We have just a bit farther to go" Madame Hooch says

"Minnie says that she is inviting my twin to school this year along with a few other exceptional young children so now we won't be the only two" Skylar says

"You have a twin? Why isnt he with you, I had a twin" Elsa says

"Yeah his name is Harry Potter Minnie says that we had to be separated for our own protection" Skylar says

"Lily's Son" Elsa says "Severus talk bout lily all the time, he wish too save her if he could go back in time"

"Why doesn't he if he could find a time turner then he could" Skylar says

"It would majorly change the timeline and the Ministry of magic could not allow that, Severus could be throw is Azkaban" Elsa says

"But they technically would never even know" Skylar points out

"Still I made him promise me too never do it" Elsa says "If he tried and the Ministry found out,... I cant lose him too"

" If I had a time turner I would turn back the clock to that day and save both my mommy and my daddy and keep my god papa out of Azkaban" Skylar says

"You look like Lily" Elsa says, despite the blonde hair Elsa looked just like Sirius Black, her hair fell in just the same way his did and she acted alot like he would have.

"My hair is the wrong color and I have daddy's eyes and I have to wear glasses," Skylar says

"You look like her, your face does, same skin tone too" Elsa says

"You look kinda like my god papa I love him so" Skylar says

"That's impossible, My father was a Muggle" Elsa says

"I'm just saying what I see" Skylar says " no need to get all defensive"

"Who was you're godfather" Elsa asks

"Minnie doesn't like me talking about him but you heard Professor Snape mention him in her office, his name is Sirius Black" Skylar says pulling out a locket with a picture of all the people who loved her when she was a baby

"Can I tell you a secrect?" Elsa whispers "I think sevy lies about who my daddy is"

"Minnie says Professor Snape is a slithery little snake and she wouldn't put lying to a child past him I mean he terrifies his students rather than encourage them" Skylar says

"There are two sides too every person, What sevy does is too protect me, Lucius malfoy always says my father is in Azkaban but a Muggle cant go too azkaban can they?" Elsa says

"I would take anything Lucius Malfoy says with a grain of salt he is untrustworthy he was on he who must not be named side" Skylar says

"But Draco agrees, and if Draco Agrees I believe him because draco is very very nice" Elsa says

"Who has Draco been raised by though he could have been taught to say that and that is why he agrees" Skylar says

"His name is Draco Malfoy" Elsa says

"I know who you are talking about his Father could have filled his head with lies and with evil thoughts" Skylar says

"No" Elsa says "Draco is not evil, and neither is mr. malfy, Mrs Malfoy maybe, Mr. Malfoy Never"

"Ok it's your choice what you believe but if something I said turns out to be true don't say I didn't warn you but I don't feel like fighting, I know a great place to go and get some good food want to come?" Skylar says

"Going somewhere without sevy knowing? Count me in" Elsa says they sneak away from Madame Hooch and head to the great hall Skylar sneaks a few plates and places them on the table immediately the plates are piled high with yummy treats and all the girls favorite foods

"So what house do you think you'll be in?" Elsa says "I'm hoping too be in Mama's house but If i'm in Gryffindor, which is the house Mr. Malfoy says my father was in, I wont be to upset about it."

"Well on my daddy's side my family has always been Gryffindor and my mommy is the first on her side and she was too so I'm pretty sure me and my brother will be too" Skylar says

"So where is you're brother?" Elsa says "Mine is at Spinners end, Onyx have no magic"

"He has to stay with Mommys mean sissy and her mean husband and mean bratty son" Skylar says

"Well that's stupid" Elsa says "He should be here with you"

"It's for his own good they mask his magical aura and keep him concealed from the bad people who want to hunt him and kill him" Skylar says

"Ahh yeah Riddle" Elsa says "Riddle isn't dead, just hiding"

"I figured as much I remember the day he came in when we were 2 months old and after he tried to kill us he didn't die but he was wounded badly so he skulked into the shadows and hides like a coward waiting to make his next move

"Riddle killed My mama, and my daddy flead" Elsa says "My daddy had long black hair, and when he was around their was always some man named Mooney. Daddy called me his little padlet. Mooney call him Pad….Padfoot I don't know something like that"

"My daddy had a friend that he called Mooney and my god papa they called him Padfoot and they called my daddy Prongs and called me pronglett and my twin baby prongs" Skylar says

"I'm sure it's just luck that my daddy and you're god papa have the same name" Elsa says

"But what are the chances they both have a friend they call Mooney?" Skylar says " maybe we should ask someone who might tell us"

"Mooney loved chocolate, When I was two we would sit out under the stars and eat choclate and he would show me the stars" Elsa says "Mooney came around more than daddy"

"My daddy's friend Mooney did the same for me aside from me eating chocolate since I was just a baby" Skylar says

"If I had too choice between Mooney and Daddy. I'd rather have mooney back. Daddy rarely came around, and when he didn him and Mommy fight" Elsa sighs

"Come with me I think I know just the person we should go see to ask about this" Skylar says shoving some of the candies on her plate into her pockets before leaving the table

"Lets go be detectives" Elsa says grabbing all the chocolate, they head to Hagrid's hut careful to avoid Madame Hooch who is frantically looking for them, Skylar knocks on the door and they wait for a response "How mad do you think Sev and Mcgonagall will be at us?" Elsa whispers

"Minnie will be worse but she will probably end up letting us off the hook because she has raised me since my mommy and daddy died" Skylar says

"Sev never lets me off the hook" Elsa says

"Yeah I figured, but no matter what happens or what they say neither of us can throw the other under the bus deal?" Skylar says

"Deal" Elsa says, just then the door opens a very large man is standing before them

"Hiya Hagrid, this is Elsa my new friend can we come in and have some tea with you?" Skylar asks to hagrid elsa looked like Sirius black.

"Um sure I suppose so I was just making a pot so perfect timing" Hagrid says standing out of the way so they can come in

"Elsa!" They hear snape calling in the distance.

"Are you two not supposed to be here?" Hagrid asks looking down at them

"No We ask Madame hooch she said we could come" Elsa lied with ease, the lie was so good skylar almost believed it was true

"Yeah we got to talking and we got some information and we want to see if you could shed some light on it for us" Skylar says she then explains everything she and Elsa had talked about

Once Skylar was finished Hagrid nervously chuckles and says " Sorry girls but I don't know anything about that stuff"

"But Hagrid you knew and were close with my daddy and his group of friends why can't you just tell us what happened after they graduated Hogwarts

"Severus always said that My mama, Diana Phoenix, came down too visit you alot in her year's" Elsa says her purple eyes momentairly turn the color that Sirius's were

"Sorry girls but it's getting late and you don't want to be caught outside after dark" Hagrid says pushing them out the door and locking it behind them

"Well that was a bust, lets go do something" Elsa says

"We could go look in the Library it's my favorite room in the whole castle" Skylar says

"Awesome! I love books" Elsa says "Lead the way" just then Mcgonagall comes up behind Skylar where Elsa can see her

"Uh oh trouble on the horizon" Elsa whispers and then grins up at Mcgonagall sheepishly

"She's behind me isn't she" Skylar mouths

"Yep" Elsa mouths

"Hello girls and just what do you think you are doing I thought you were practicing your flying skills with Madame Hooch" Mcgonagall says

"Visiting Hagrid with permision" Elsa says

"Madame Hooch said you wandered off and that she did not even get asked if you could go anywhere" Mcgonagal says

"It was on our Authiority" Elsa says, Mcgonagall could see elsa was going too be a troublesome student

"Miss Phoenix students and children do not have the authority to leave somewhere or go somewhere without permission" Mcgonagall says

"My friend Mooney said he and Daddy and their two friends did it all the time" Elsa says

"Well I assure you that if they did it was very fortunate for them that they did not get caught

"It was my fault Minnie, I asked her if she wanted to go to the great hall to get some sweets and then we got to taking and we wanted to ask Hagrid something and then we were just heading to the library to read together, I'm sorry Minnie I just wanted to get to know my knew friend" Skylar says

"ELISA PHOENIX-BLACK WHERE THE BLOODY HELL ARE YOU!" Snape yells from a distance

"Uh oh. Gotta Bolt" Elsa says running in the oppiste direction and Skylar follows as Snape comes down too them "Mcgonagall have you seen Elsa"

"She just went that way" Mcgonagall says pointing toward a rock

"Merlin's underpants that child is going too be the death of me" Snape says

"You chose to take her on as your own Severus and you have to live with that, I will never understand why you did that seeing as you hate her father" Mcgonagall says

"I did it for Lupin" Snape says "Because he couldn't. She is not too know who her father is. Not yet"

"You don't like Remus either and yet you did him a favor?" Mcgonagall asks confused

"No I dont, but I owed him a life debt" Snape says

"You know we are in a similar boat Severus we were both entrusted with the care of two amazingly bright and very important children and we have to protect them, at some point they will both need to learn the truth of who exactly they are" Mcgonagall says placing an arm around Snape's shoulders

"And when the time comes she will know, but i fear she will find out before she is ready. She is her fathers daughter" Snape says

"Yes indeed and Skylaris is the same way and she is already making friends with Elsa and they will probably figure it out twice as fast with them together" Mcgonagall says

"You know last night elsa charmed all my robes into gryffindor colors, it took me and Lucius two hours too undo her spell. I don't think it was a known spell" Snape says

"Skylaris did the same with all of the banners in the great hall which were set up in the Hogwarts crest and when I walked in they were Gryffindor" Mcgonagall says

"May hogwarts survive the young children of the Maruarders" Snape says "And whoever else elsa may befreind"

"It is going to get worse we have many young children coming including Skylaris's twin Harry" Mcgonagall says

"Yes, I heard the weasley twins and Draco are getting their letter early, and possible ron weasley too?" Snape says

"Yes all of them and a muggle born Hermione Granger, perhaps even young Ginny Weasley will be coming but I might wait for next year on her, and Neville Longbottom is coming per his grandmother's request" Mcgonagall says

"Elsa is friends with the twins, all i have to say on them is Merlin help the house they land in" Snape says

"It will be Gryffindor for the lot of the Weasleys I am sure of it" Mcgonagall

"Have fun with them, especially if elsa gets in with them" Severus says

"Yeah and if the others get in there as well I am going to have chaos on my hands for the next seven years" Mcgonagall says

"I think you were going too have chaos no matter who goes where" Snape says

"Well I am going to bet My house doesn't win the cup anytime soon with the lot I'm about to be dealt with" Mcgonagall says

"So Albus has sent a letter too a half demon child" Severus says "The boy's name is Wolf Demonshadow"

"Yes I am aware" Mcgonagall says

"Is he out of his mind? That's against the use of magic law." Snape says

"Severus our world is changing its time we did too at some point children like that coming here will be totally normal to us" Mcgonagall scold Snape

"I hope we dont come too regret this" Snape says "He could of settled with the half cat triplets, Knight, Alastor, and Willow Mareni"

"Don't forget the Elf twins Imogen and Darra Anasaki" Mcgonagall says pulling out a flask and drinking from it then offering it to Snape

"Yes how could i forget them" Snape says as Mcgonagall sees a shirtless boy approching from behind Snape. This boy had dark skin and Silver hair, he wore dark sunglasses.

"Hey Minnie, Sev, have you seen Albus My dad has locked me out of the chamber" The boy says; the boy's name was Gwen Jaffernou

"Um I think he is in his study probably pacing around getting ready for the school year" Mcgonagall says

"Is it true I'm going through classes this year? Dad keeps saying so" Gwen says

"Yes as long as you stay in human form and you call us by professors Mcgonagall and Snape and the same for the other professors, Mcgonagall says "and you must wear the uniform

"Sure. I'm going Rat hunting" Gwen says "After I find Alb. I need too talk too him about my little deadly gaze problem" Gwen heads back too the castle

"So what are we going to do about Elsa and Skylaris right now they broke the rules they have to get used to being punished" Mcgonagall asks

"Detention when school starts" Snape says as Mcgonagall sees Elsa and Skylar sneaking up towards the castle

"I'm thinking first two weeks of class after class before dinner" Mcgonagall says "OI WHERE DO YOU THINK YOU TWO ARE GOING GET BACK HERE WE HAVE DECIDED ON YOUR PUNISHMENT"

"PLACES!" Elsa screams back and she grabs skylars arm and drags her into the castle at a run

"We should go after them" Snape says

"Ah let them play for the rest of the night, Skylar hasn't had any social interaction with anyone near her age and hasn't even left Hogwarts and Hogsmeade since she was 2 months old" Mcgonagall says

"Elsa has never had any positive interaction for a long time, her last interaction with those her age, aside from Fred and George weasley, was negitive at the orpahange I saved her from"

"So it's agreed we let them play for a while longer before dinner and then we deal out their punishment" Mcgonagall says

"They'll come when they are tired or hungry" Snape says

"Exactly so what do we do now everything is all set for start of term in a few days" Mcgonagall asks taking another swig from her flask and handing it to Snape " I vote we get drunk while the girls are entertaining each other"

"Well-" There is a huge boom from the castle and moments later they see Mrs. Norris run from the castle

"Should we worry about that or just let Things happen?" Mcgonagall says

"No, elsa probably dung bombed the cat, lets let her get it out of her system" Snape says then they see a huge wave of water come up out of the lake and splash into the castle flooding the halls, they see Elsa and Skylar riding the wave from the castle to the lake

"That one was Skylar maybe those two will get along but I think they may not be the best influences on each other

"Lets hope they dont make us keel over from stress" Snape says "And maybe they will find someone who is a good influence on them"

"Knowing Skylaris probably not" Mcgonagall says

"Knowing Elisa she'll change them too her side. These are going to be a long seven year's" Snape says as they see the water turn into rum

"Yep" Mcgonagall says filling up her flask with the now run river flowing from the castle to the lake

"God damnit she learned the spell" Snape says

"Skylaris learned that spell a year ago" Mcgonagall says

"That was the last spell elsa needed too learn. I was putting that off for a reason, she always wants too turn my ice into rum" Snape says

"Girl is just like her father at her age you know he did that all the time back then" Mcgonagall says pulling out 40 more flasks and fills them up with the rum " better get it now before we have to turn it back Severus" She hands Snape 4 flasks of his own

"Dont remind me, the first word out of her mouth when she saw me was Snivellus" Severus says charming many flasks too fill themselves

"SNAAAAAAKKKKKKKKKKKKEEEEEEEEEEEEEEEEEEEEEEE!" Elsa yells from inside of Hogwarts "GIANT SNAKE!" moments later she and Skylar come running out of the castle straight to Mcgonagall and Snape

"I didn't do it" Gwen yells from in hogwarts

"Minnie….. bi…..big … Snake….. scary…...wandering…around the halls" Skylar says panting and passing out

"S….Sev….. G….Giant…. Snake…..big scary black snake" Elsa says "I'm scared, Riddle not here right?"

"No Elsa he's not here" Snape said

"Minnie why big scary snake in castle" Skylar says

"Big snake half human, is it trying to eat person?" Elsa asks reaching into snape's potion bag

"Actually girls that is Gwen he will be joining you at school this year along with a few other half creature half human hybrid children" Mcgonagall says picking Skylar up

"No snake" Elsa says pulling a stuffed Zebra from the bag

"A… Are they nice?" Skylar says

"Well I can't speak for all of them but Gwen is very nice I have known him since his birth" Mcgonagall says accioing Skylar's stuffed Horse buddy

"He eat people no?" Elsa says

"No Darling, Gwen doesn't eat living people" Snape says with a smirk and elsa screams then faints

"Hey um I might of scared the girls" Gwen says slythering out too them eating a live rat.

"And that reason is why Mcgonagall told you to stay human" Snape scolds the half basilisk boy

"Yeah sorry" Gwen says "You know what, I'm going to go find my dad"

"Why is it you never listen to me Gwen I am only doing things that are best for both you and the other students" Mcgonagall says

"I do listen… I just hate being human" Gwen says transforming fully and slythering off to the chamber of Secrets
