Disclaimer: All rights to Harry Potter and its Characters belong to J. K. Rowling. I make no money with this story.

A/N: This is my first try at writing a fanfiction. English was not the first language I learned, and I may make some grammatical errors and I will apologize for that beforehand. If you see any errors be they grammatical or with the HP canon write them to me and I will fix them.

This is an AU story. The main two changes I made to the Universe in my story are the existence of Sirius Blacks daughter Meridiana Black and that Harry is more realistically affected by his treatment at the hands of the Dursleys, he is a bit less forgiving and it is not easy to earn his trust, and I probably made him a bit smarter just because I want him to be able to stand up to Voldemort and his Death Eaters without having Felix felizis injected in his blood. I will try not to really bash characters, but Harry won't be friends with Hermione or Ron and Dumbledore will not be his Mentor although he will not be evil/manipulative either.

The Pairing will be Harry/OC!Sirius Daughter (Meridiana Black) other pairings will probably not play a major role and will be decided later in the story if you want a pairing that doesn't involve Harry you can let me know and I will try to implement it. Pairings will start in 3. Year.

Now I hope you will have fun with with my first story

Prologue

There was a loud crack that could be heard in the otherwise silent neighborhood in the little town of Godrics Hollow as a man dressed in long flowing black Robes appeared seemingly out of thin Air. He had just received the Information where James Potter and his mudblood wife were hiding the Child that supposedly had enough power to vanquish Lord Voldemort. He didn't really think that the child could do so even as an adult but even the mere notion of having a chance to kill him would give Dumbledore and his Order hope. This hope would be crushed tonight and with it two important members of the Order. Well perhaps only one should he grant his loyal follower Severus the wish to have the mudblood, he was still thinking about it.

He was now standing in front of a two-story house with a little garden up front. He unlocked the garden door and made his way to the front door. Halfway to the small house Voldemort pulled a stone that had several complicated looking runes carved upon it out of his pocket and sent a small pulse of his magic into it, the stone would guarantee that no one could use any conventional magical transportation in a 200 feet radius. The Symbols on the stone were glowing now and when he put it on the ground there was a pulse of magic that signaled that the wards were in place.

He continued his way to the front door which he simply blew off its hinges with a barely noticeable flick of his wand. There was no use in being subtle James Potter probably felt the wards as they activated, he was a wizard of noble blood after all. In the entrance hall awaited him said wizard tough Voldemort noticed that Potter seemed to have forgotten his wand, pathetic blood traitor. The Traitor tried to wandlessly banish a vase at him, but the charm proved too weak for the vase to even reach him.

Voldemort gathered his magic and whispered. "Avada Kedavra".

while he was casting the spell, Potter transformed into a stag but before the Animagus could charge at him the green light enveloped the room and Potter reverted back to his human form before slumping to the ground whit a muffled thud.

Voldemort continued his way through the little house and went up the stairs. He could hear the sobs of a woman coming from the door to the right of him. He honestly wanted to laugh at the stupidity of the little mudblood she could have at least tried to hide from him and make it a little fun. He opened the unlocked door of the room and came face to face with the tear-stricken face of Lily Potter as she stood protectively in front of two cribs.

"Step aside you foolish girl" Voldemort said harshly. He decided that it would be a fair reward for Severus to have her, he was after all generous to those who served him well.

"No never… Please take me instead... Have mercy…please…" she said desperately.

"Get out of my way or the same fate as your sons shall await you" He threatened.

But she stubbornly stood her ground and once again pleaded: "Have mercy… please mercy… please"

His patience with her ended and with two harsh words and a flick of his wand green light filled the room for a moment before her body dropped to the ground lifelessly.

He stepped over the woman's body and now stood before the cribs. In both of them was a baby of approximately the same age. One was a dark-haired girl who seemed to be sleeping. She could only be Meridiana Black the offspring of Sirius Black and some Order member. He was already readying himself to kill her when a recent memory came to his mind. His loyal follower Bellatrix told him she was not able to have children. It would be ideal to have Meridiana here be raised by Bella. She was the black heiress and he could already feel a bit of magic in her she would make a good future servant. He sent a powerful sleeping charm at her, so he could easily transport her after he eliminated the young Potter boy.

Now he finally turned to see the Baby that could apparently grow to vanquish him. He reached out with his magic to feel the boys magical core and was mildly surprised to see the boy truly did have a lot of potential, perhaps he would have grown to be equal to Tom Riddle but to Lord Voldemort who underwent dozens of Rituals to enhance himself, ha! He wouldn't stand a chance.

Voldemort aimed his wand at the boys head and said triumphantly. "Avada Kedavra"

As expected, there was a flash of green light but instead of fading the light seemed to come back at him even brighter. And once it hit him unimaginable pain cursed trough his body as it was torn apart. Unknowingly his body wasn't the only thing being torn apart.

An hour later Sirius Black arrived on his motorbike. He planned to take his little girl back home to the cottage he and Catherin had bought to raise their little daughter. But when he saw that the front door of his best friend's house was blown off its hinges he was instantly on high alert and a strong feeling of dread filled him.

He walked into the house and the first thing he saw was James's body lying beside a broken vase. He rushed to the side of his best friend but when he checked the pulse and felt nothing he burst into tears. But he had to gather himself he had to check if his little girl was all right, he didn't think he could live knowing he wasn't there to protect her. So, he stood up and rushed up the stairs and into the room he knew to be the nursery. There he found Lily's body lying in front of the two crips, dead. He wanted to simply break down into tears in hope of waking up from this horrible nightmare, but he had to check on the babies. Little harry was crying and blood was running down his face, but what worried him a lot more was that Meridiana was not moving and nor crying, he took her in his arms and began to sob and wish that it was all a nightmare.

But then he heard it, a faint exhale of air coming from Meridiana. And it was as if the world had stopped spinning! He wanted to laugh in joy! But instead a sound between a broken laugh and a sob escaped his lips.

After a few minutes of grieving he had enough self-control to take his godson out of the crip as well and clean the blood on his face with a quick spell as well as heal the scar that the attacker, probably Voldemort, had left behind. But his spell that would normally heal wounds twice that deep and wide had no effect on the scar what so ever, so he simply cleaned the blood and took both babies down the stairs. Downstairs he sat down on a chair and contemplated his next move. But first he thought: "how could this have happened? Dumbledore said the charm was unbreakable, unless… Oh no… THAT FILTHY LITTLE RAT!" he couldn't believe Wormtail would betray them, but he obviously had and suddenly all his grief went away only to be replaced by a burning hatred for Wormtail. He needed revenge! He needed to kill the little rat and avenge his friends!

He was so caught up in his thoughts that he nearly didn't notice the arrival of Hagrid. The man came into the house and looked at James's dead body completely shocked before whispering. "oh no…" and then he turned to Sirius and asked. "what happened?"

"They are dead only Harry and Meridiana survived Lily and James are…gone" Sirius replied in a hollow tone.

Hagrid nodded sadly and said. "Dumbledore ordered me to bring any survivors to Hogwarts"

Sirius contemplated what Hagrid said. He didn't want to give his little girl or his godson away, but he could come back for them and they would be safe at Hogwarts for the moment while he went after the treacherous rat. His anger overwhelmed any other emotion in his mind and he handed the Babies over while saying: „Take good care of them Hagrid, you can take yourself my Motorbike I won't be needing it for some time since you shouldn't use portkeys with Babies."

Hagrid accepted the Babies and promised. "I will take them to Dumbledore safely"

With that Hagrid turned around and went out of the house. He could hear the motor of his bike roar to life as Hagrid flew into the nightsky with it.

And with that Sirius went outside of the wards and spinned on his heel and with a loud crack apparated to peters pathetic apartment determined to hunt the rat down and avenge his friends.

I hope my first chapter was understandable and didn't have too many flaws. The next chapter will be postet tomorrow and after that new chapters will be posted weekly. Should you have any questions feel free to ask them and I will try my best to answer them.
