AN: This is my first fanfic and first story I have ever tried to write. Please take that into consideration as you read this story. I read a LOT of fanfiction and have had this idea buzzing around in my head for a while. I am honestly not sure exactly how I want this story to go… I guess I'm just going to write and see what happens.

This is most likely a OC/Snape paring and eventual mentor Snape OR OC/ Sirius pairing... but we'll see what happens.

Godmother

Chapter 1

Jessalyn Jax stood at the door of number twelve private drive, listening in growing anger at the voices within.

"Freak! Get in here and clean up your mess!"

"Daddy, he dripped blood on my shoe!"

"Do something about that nose, or I'm locking you in the cupboard!"

The 'freak' was no doubt my godson. Lock him in a cupboard? Petunia would do that to Lily's son? On his seventh birthday? How dare she. I took a moment to get my breathing under control and my occlumency shields up so that no matter what I felt in the next few moments I would not act rashly. When I was ready, I knocked on the door.

The door was opened by a very large man who squinted out at me.

"Who are you? What do you want?" He asked rudely. I smiled, making eye contact, and leaned in conspiratorially to whisper, "I am here with the Company, and I have some very exciting news. Gather your family in the living room and I shall tell you all together." The fat man's eyes nearly bulged from their sockets as he ushered me inside calling to Petunia and Dudley as he did so. He shot a glare into the kitchen, and I heard a chair pull out at the table. I resisted looking into the kitchen was I followed them to the living room. I knew if I cought a glimpse of my godson bleeding after the things I'd seen in Vernon's mind, I might do serious and lasting harm to these people. With those wards and what they imply, I still need them alive.

"Vernon, what's all this about?" Petunia said as she sat down, eyeing me curiously. My grin widened. She doesn't remember me, but no matter. She'll be reminded soon enough.

"I have some very exciting news!" I said as I moved to the only other chair available in the living room. With a discreet flick of my wrist my wand dropped into my hand as I made a show of adjusting the ugly flowered pillows. I cast a quiet silencing charm on the house so the neighbors wouldn't hear us, turned around, sat down and smiled at Petunia. She glanced at Vernon worriedly. My grin turned wolfish.

"Oh my, let me introduce myself! My name is Jessalyn Jax and I am Harry Potters Godmother." With a flick of my wand the blinds closed and the room fell into darkness. Vernon made to rise from his seat and I quickly pushed him back down and pinned him to the chair, my hand at his throat, wand pointed in his face.

"You, miserable pig, will sit and not move or I will turn your son into a fish. Do I make myself clear?"

"You can't do that" Vernon spluttered "Your kind have laws about that sort of thing."

"Oh yes, just as your kind have laws about embezzlement and child abuse. Shall we call them about that, or shall we keep this to ourselves?" I arched an eyebrow menacingly at him. Petunia gasped, finally recognizing me, and gripped her husband's arm in warning.

"Y-y-you! But you disappeared! They told us you were dead!" Petunia wailed in outrage. Her son clutched a bag of chips and was eating with increasing aggression, sensing that he might not have the chance to eat soon.

"Yes I was gone for a while, but I am clearly not dead Pet, please keep up. I have only been here for 5 minutes and already I have seen how you mistreat your nephew. I want a full explanation before we work out future living arrangements." I stepped back from Vernon and glanced toward the kitchen and the small seven year old sitting at the table wide eyed and bloody nosed. Vernon took this opportunity to jump out of his seat and punch me. Unfortunately, due to his size, his quick thinking did not amount to quick movement and I dodged his wild swing. Sidestepping, I tripped him and kneed him in the face on his way down. That was when Dudley decided to make a run for it. Petunia screamed at him to stop as I turned my wand on him. Of course he didn't listen to her, and so I turned him into a fat gold fish. I glared at petunia and called over my shoulder, "Harry dear, please get me a bowl of water."

He obeyed instantly, still holding a rag to his nose, he brought it into the living room and sat it down by the flopping fish. Dudley jumped into the bowl on his own and swam around madly for a moment before settling at the bottom to watch me.

Petunia gaped at me in horror as I handed her the bowl with her son in it, then levitated an unconscious Vernon to the couch next to her.

"Now, explain yourself Pet." I nearly spat at her. She flinched at the nickname.

"We don't want him bringing that unnaturalness into our home. I can't have it rubbing off on my son. Lily tore my family apart once with all her freakishness, and I won't have that in my family now!" Petunia said fiercely. I stared at her for a moment before laughing.

"Your son has as much a chance as Lily did to be born magical, if not more so! You already know it's in your blood somewhere. What were you trying to do, beat the magic out of the boy? Did you honestly think that would work?" Petunia looked somewhat horrified at her son, thinking about what I said. "Pet, don't you realize that Harry is already bound by fate to be a wizard, and more powerful than you could imagine. He will have capabilities you cannot begin to understand, and you have abused him his whole childhood. Did you think he would just leave and never bother you again? Did you think some law would protect you from retribution from him? How on earth do you plan to endear him to you? Should he be grateful for the way you've cared for him? You really don't think do you, Pet? Just follow along blindly just like always." I shook my head as she looked on in horror at me.

Harry looked up at me just as scared and I realized I had made a horrible first impression on my young godson.

"Petunia, tell the boy who I am. Tell him everything." I said forcefully, jarring her from her thoughts.

"Harry come here. Sit down. Let me tell you a story."
