(Sirius Black POV)

Entering the Black manor, I noticed the lack of noise or any sign of Bellatrix. Figuring she was elsewhere, I walked towards the fireplace to reflect on my trial, the people I met, and my last conversation with Amelia. But just as I entered the living room, there sitting on the oversized couch was Bellatrix. However, she was naked, her legs apart, and thanks to my improved vision, I could see her gleaming arousal across the room. She was holding a wine glass in one hand while motioning for me to approach with her index finger from the other. She smiled coyly.

"Figured today can be a celebratory night," she said.

I gave her an aggressive smile, and as I approached her, all of my previous thoughts vanished. When I got to her, I snatched the drink from her and quickly banished it away.

"Hey, I was still drinking."

I got down on my knees rather than responding to her. I took her by the hips and brought her nether region to my mouth. She exclaimed, "So forceful!"

Her breasts bounded up and down as she wiggled her hips and arched her back, enhancing their size. My eyes ate up her body as they admired her attractiveness. Her pale complexion shone in the light of the fire, and her dark hair flowed around her face. She writhed and moaned, attempting to get away from me, but I wouldn't allow her, instead tickling her clit with my tongue. I could see her enjoying every minute of what I was doing. She came immediately and soaked my face.

"Ohhhh" she groaned

I slowly stood up and gave her little kisses from her navel to her breasts before grabbing her face and kissing her. Her hand moves and fishes my dick while we kiss. She seized my privates and dragged them to her door. When she gave the signal, I pushed firmly. The loud pounding noises didn't take long to arrive because she was already soaked from earlier.

*Slap Slap Slap*

I swiftly reached my breaking point after experiencing delight, finally achieving freedom, and that kiss with Amelia. She made a loud moan.
As I unloaded into her womb and filled her with my cum, my eyelids slid back. She finally lost control of her tears and sobbed aloud. She eventually slouched against me and began to pant after a while.

~Next Morning~

As I stood by the window in the early morning, I considered what lay ahead. Now that I was free from any death orders, it was time to restart the businesses of House Black. I also had other tasks in mind: finding Voldemort and destroying his Horcruxes, ensuring that this world's Harry or Rose Potter would live a good life, finding a cure to wake Lily up, and dealing with Malfoy.

However, something felt off. Every time I thought about these ideas, my magic seemed wonky, as if it was resisting them. I was so absorbed in trying to figure out the problem that I didn't notice Bellatrix approaching me. She draped herself over me.

I took a deep breath, feeling the warmth of Bellatrix's body as she pressed against me. "What are you thinking about?" she asked, nibbling on my ear.
"I have a feeling that now that I'm free, things are still not over. I still need to do stuff," I replied.

"Hmm, let me guess," Bellatrix continued, "You thought that now you're free, you can just go off into the sunset without any worries, right?"

"Yeah," I admitted.

"You see, you could have done that, but since you performed a magical ritual on yourself, you should face the consequences."

My anxiety spiked as I wondered if I had somehow messed up the rituals. Sensing my tension, Bellatrix continued, "It's not life-threatening magic, but you do know magic always demands a price, right?"

"Your goal when performing the ritual was to get stronger, but you can't just get stronger for the sake of getting stronger. As we magical beings grow older, most get weaker, but very few get stronger. Like Dumbledore and Voldemort."

"Your rituals did make you stronger, but do you want to stop there and not let your magic grow? That's tied to your intent and future goals. There have been many magical throughout history, but very few got very strong. They all had one thing in common: they stood for a cause or did big things. The founders, Merlin, Dumbledore, Grindelwald, Voldemort… No matter whether it was a good cause or a bad cause. They all had their ideals or desires for control. Sure, they were talented, but their goals and motivations pushed them to reach heights very few could match."

"So, what is your choice? Stay and wait around or do something big? Sure, rebuilding House Black is a good goal, but it's not big enough."

As I listened to Bellatrix's monologue, my annoyance grew. I hated being forced into doing things, but I also knew that just sitting around and enjoying life's pleasures wouldn't be fulfilling in the long run. Immortality wasn't something I desired either; I had seen the bizarre things immortals did to pass the time, such as the antics of the Greek pantheon. A long life was appealing but not an eternal one.

I was already quite powerful, but did I want to stop here? This alternate reality was uncertain, and I knew that raw magical power would be invaluable in tackling any situation. So, I pondered over what goal I should strive for.

Bellatrix gave examples of individuals who brought significant change to the magical world. The founders created a school that forever changed the dynamics of magical education. Grindelwald sought to have the magical world rule over Muggles and break the Statute of Secrecy. Dumbledore aimed to stop Grindelwald and establish a world of total peace and equality among all races. Voldemort's goal was world domination, though whether he truly wanted to promote a pure-blood agenda was debatable, considering he was a half-blood himself.

As I leaned back into Bellatrix's soft embrace, I continued thinking. She remained silent. I needed a logical and well-thought-out goal that would allow me to grow as a wizard and make a meaningful impact on the magical world.

All races are equal and should love each other?

Achieving complete equality among all races would indeed be a difficult task. No matter how hard I tried to bring together magical children of different races, there would always be some inherent differences and prejudices that would be hard to overcome. Even if I managed to take every magical child from other races and raise them together, likely, they would still form groups and keep their distance from the goblin, centaur, or giant children. The differences between various magical races run deep, stemming from their physical appearance, even magic.

Prejudice of muggle-born and purebloods? Hmm, perhaps one way to address the issue of prejudice between Muggle-borns and pure-bloods is to develop a school or program for younger kids, letting them interact with one another at a young age. The kids would have firsthand experience interacting with Muggle-born people as their peers, regardless of whether their parents tried to impart the idea that pure-bloods are superior. Perhaps at the of pre-schooling? But this is still a very small goal, and I would get tremendous opposition from the ministry.

World Domination? Too much work, people will always be unhappy with the status quo. I would be too busy to enjoy life and putting down rebellions.
But just as I thought about rebellions, I thought about my previous life. Muggles, all the advanced technology. I couldn't help but think of the rapidly advancing Muggle world and the inevitable discovery of magic. I believed such a revelation would lead to hostility from various religious groups and the general public, especially once they discovered the lengths magical beings went to keep magic a secret. This fear of magic could spark a war leading to nuclear wars and the extinction of the magical. Could I make a ward against nukes?

Yes, working towards creating a separate dimension could be a more feasible approach. Rather than attempting to destroy the Muggle world, which would be both impossible and unwise, I could focus on developing a large-scale magical solution. Ideas began to rapidly fill my mind, such as implementing an expansive Fidelius Charm to hide all traces of magic, or creating dimensional barriers to separate the magical and non-magical worlds.

To bring any of these plans to fruition, I would need the support of a vast network of intelligent and influential researchers and the cooperation of various Departments of Magic from around the world.

However, I couldn't simply approach them and start discussing these ideas. I would need significant influence within the magical community to lead such an endeavor. I wondered if Dumbledore would support this concept or oppose it.

I realized that I needed to be seen as a pillar of society, someone others could rely on. Various plans started forming in my head. One possibility was to create a fake dark lord, only to step in and save everyone, effectively becoming a hero. Another idea was to get ride Dumbledore and establish me as the next coming of Merlin, ushering in a new era of magical prowess and leadership. Alternatively, I could guide Rose Potter on a path to greatness, nurturing her potential to become the next Merlin and using her influence to achieve my goals.

As I pondered these thoughts, I could feel my magic stirring with excitement.

Now that the end goal was to become the next Figurehead of Magical Britain, I had a lot of work to do, which included making the news a lot. Some headlines could be used if they were still canon, including "Saving the School from Basilisk," "Lord Black Saves Women from Mind Trickster Lockhart," and some unsavory ones like Bellatrix fishing out supporters of Voldemort, since Bellatrix is supposed to be dead, and no one knows of her betrayal, leading them to attack places, creating chaos, then me "appearing" and saving everyone. This would not only take out Voldemort's remaining followers but also cement my power in the minds of the public.

To be on the safe side, I would need a lot of support from Amelia so as not to be declared a vigilante and become a wanted man once again. However, I needed to completely eliminate any hidden wariness the wizarding world held toward me. What better way than to be seen with their beloved heroine? Girl-who-lived. Was it altruistic to meet my goddaughter after a year with selfish intentions? Eh, well, it is what it is. Anyway, I was a wanted man, she would understand, or not.

That's why I was at the iconic 4 Privet Drive, Surrey. A few mental scans helped me locate the Dursley house, and I placed a discreet "don't notice me" charm on the Dumbledore squib spy living next door. Some nervousness crept into me as I walked up the porch, considering this was an alternate universe. I didn't know what to expect from Rose, especially given that in canon, Potter stayed with his aunt and uncle for 11 years, while in this world, Potter has living here for 18 years.

"Knock, knock."

Knocking on the door, I waited. A bony woman with blonde hair, a "rather horsey" face, and a very long neck opened the door. "Who are you?" she asked with a perpetual scowl. Not to toot my own horn, but in this body after the ritual, I was pretty handsome, so it was strange how she quickly ignored my appearance. Wasn't there a saying about good-looking people having an easier time? Maybe she was extremely loyal. Whatever, I ignored my errant thoughts.

I didn't bother to reply and sent a Legilimency probe into her mind to see how Rose grew up and if there were any complications. Petunia didn't feel anything other than a mild headache forming as she thought about how she raised her niece.

Coming out of my stupor, as I wasn't expecting this, Rose was aware of magic and capable of some form of it for all intents and purposes. Most of the time, she used it on her family. From the looks of it, it started as a form of self-defense and later turned into spite or petty revenge, nothing serious just a push or shove when they she was yelled at. It seemed like she had mellowed out; I wouldn't want to deal with a nascent dark lord.

"I am here for Rose Potter; I am her godfather."

Petunia gasped lightly and stiffened. Her eyes constricted in momentary fear, but quickly she glared at me with loathing. She was about to start shouting when she flinched, not because of my behavior but because of ingrained fear from how Rose lashed out whenever she shouted. She took a deep breath and stiffly said, "I will call her." She quickly closed the door. Well, she was rude, or poor lady.

Was I disturbed by how Rose treated them? Kind of. She started showing aggression at a young age in response to anything she perceived as a slight. One could argue that the Dursleys never raised a hand against her, but from Petunia's memories, they had considered punishing her physically before becoming scared by the magic the growing Rose exhibited.

My musings were cut short by the door opening. A red-headed girl with green eyes came out. She looked a lot like Lily from my memories. Quickly offering the best greeting I could muster, I said, "Hi, Rose. Sorry for the late meeting. I am your godfather, Sirius Black."

(Rose Potter Pov)

When her aunt came and told her someone who claimed to be her godfather was at the door and was asking for her, disbelief, a mix of nervousness, apprehension, and excitement – emotions she rarely felt – began bubbling within her. She tried to maintain her composure and tried to walk slowly toward the door, but her legs automatically moved briskly.

'Family... My relative,' she thought, though a dark idea reared its head in her mind: "Why is he so late?", "Did he abandon me?", "Petunia never told me about anyone else besides my mother."

She tried to suppress the resentment or erase it, but it was difficult. Sometimes, when the Dursleys celebrated holidays or Dudley received birthday gifts, she wished she had someone there for her too. But now she had grown up. Again, her thoughts turned dark.

'Refuse to meet him,' 'Tell him to get lost,' 'You don't need him anymore,' but these thoughts were crushed just by the weight of meeting someone like her. Someone who had magic. She would give her so-called godfather a chance. She hoped he had good excuses, or she would take revenge on someone who had abandoned her.

Resolutely, she held the doorknob, though her hand shook slightly. She still opened it.

There stood her 'godfather.' He was, well, how she imagined her 'people' to be. She had seen how she grew up; she might not be vain, but she felt confident about her appearance. She attributed her appearance to magic. How could she not? She was Petunia's niece by blood, but Petunia was average compared to her. So she automatically built an ideal image of her godfather when Petunia mentioned him.

'Tall, handsome, strong, powerful man.'

Well, she was wrong; he had exceeded the image she built. He was even better. Moreover, he had this presence around him that just demanded respect.

Though he was dressed in clothes she considered mundane, as Petunia described how wizards used to wear robes, her thoughts were interrupted when he introduced himself.

"Hi Rose, sorry for the late meeting. I am your godfather, Sirius Black."
