"Ughh!"

I awoke to find myself in a dingy jail cell, surrounded by bars. Disorientated and in pain, I tried to stand up, but aches and cramps took hold, causing me to fall.

"Fuck!" I cursed.

As I looked around the room, I realized that I was not in my own body and must have experienced transmigration. The atmosphere was horrible, and I concluded that I was in a jail cell. I didn't have any breathing problems, which meant that I wasn't dead, but my soul had been transported to another body for someone's entertainment. I could only assume that I had been sent on a mission and that my memories had been erased. I couldn't believe I was in this situation, stuck in a jail cell.

"Keep it down, black. Your betters are trying to sleep," a voice jeered.

"Hahaha," others laughed.

Despite the pain, I crawled forward to peer through the bars and saw that my fellow prisoners were laughing at my predicament. The jeers led me to guess who I was - Sirius Black. The realization was accompanied by a sharp pain in my head, and I felt like my nerves were on fire. As memories flooded my mind, I struggled to maintain my identity and not become an amalgamation of Sirius Black.

"Huff huff huff," I breathed deeply, trying to calm myself.

As I meditated, I slowly began to experience the memories of the late Sirius Black. A childhood filled with training and torture by his mother, Walburga Black. Spells, fights, a bond with his brother, and a defiance of his parents by going to Hogwarts and being sorted into Gryffindor. Love, friendship, and becoming an animagus. Running away to live with James' family, fighting against a dark lord, being named a godfather, and ultimately being betrayed and ending up in jail.

These memories brought with them a flood of emotions, mainly disappointment and sadness. I was disappointed in myself for betraying my mercenary group and putting my own needs first. As I reflected on my previous life, I felt ashamed of my actions.

"Focus," I told myself.

The thing that stood out most was that Harry Potter was a girl and Lily was still alive, but in a coma-like state. My first course of action was to escape, and I planned to do so by using my animagus form, just as Sirius had done.


It was a strange feeling, like being a dog. Your five senses become enhanced, but you shrink in size. I wasn't sure if this applied to my new form and if my senses would also be boosted. As I adjusted to my new reality, I felt a chill run down my spine and my vision became blurry. The screams of my fellow prisoners made it difficult to focus.

Whimpers escaped my mouth as memories of my deepest fears and past experiences came flooding back. The faces of those I had betrayed in my previous life haunted me, and I saw James Potter's dead body along with Peter Pettigrew's laughing face as he declared my betrayal. As my happy emotions faded away, I tried to reach for something within me, like magic. Fueled by desperation and the need for survival, I felt a new source of energy building within me. I grabbed onto it and pushed as much as I could towards the approaching dementor. My vision cleared as the magic left me, and I quickly hid in a corner of the cell, making sure my back was facing the bars.

I had expected to feel the cold and danger from the dementors, as described in the books, but the reality of their power was much more frightening. I had four days to escape Azkaban, and I had taken note of the guards' schedules and the route they took me in, as well as the layout of the place. Thankfully, Sirius was smart enough not to transform into his animagus form in front of the guards, otherwise they would know his secret.

~Days Later~

As soon as the guard threw the food and turned around, I transformed into a black grimm, slithered through the doors, and jumped onto his back. I then attacked his throat, tearing it apart, and snatched the wand from his holster.

"What the... Ahhhhhh! Motherf*cker, you're a bloody animagus..."

"Please, no! I don't want to die..."

Transforming back into a human, I picked up the guard's wand and instinctively cast a cutting hex on his neck, ending his life. Absorbing Black's memories has given me the same level of proficiency as him, but for more complex spells, I would need to practice more.

"Hey, blood traitor! Help us, and I'll help you regain the Lord's favor."

"Hey Siri, assist me in escaping, and we'll be good as new. Doesn't family come first?"

"Ha! You killed him. You broke Dumbledore's rule, and the old coot will be devastated."

Listening to their conversation, I focused on my fellow prisoners. Two options came to mind: killing them all and running or taking them with me, stunned. However, the first option would compromise my plans as they would know I was the only one missing and therefore, responsible for the killings. I couldn't yet perform complex magic like transfiguring them into sticks and carrying them in my pocket. It was amusing how I could transform into a dog but not perform the same on another human. Perhaps this body was more suited for transformations than other complex magic. An idea then came to me, to use the old elf from Blackhouse. But first, I would need to break through the wards restricting the elf from being summoned.

I turned to the group and began using stunners on the ten people one by one. Their poor nutrition and prolonged exposure to the dementors made them vulnerable and easy targets. Sirius, being accustomed to transforming into a dog, was not as badly affected by the dementors as the other criminals in the facility.

"You bastard, what are you doing?"

"Blood Traitor!"

"Bastard"

As soon as the last person fell, I unlocked their door using Alohomora, levitated them all out, and brought them to Rookwood's cell to create the illusion that he was responsible. However, the authorities could easily see through the deception. I then stepped away from the cell and delved deep to tap into the well of energy within me. I channeled it all into my wand and cast a blasting spell on the cell wall.

"Bombarda!"

The air around me simmered, and a dark glow appeared in my eyes. A heavy feeling descended upon the atmosphere, and then an orange light flickered from my wand, followed by a loud bang and a shower of stones and gravel. I had tried to gauge the distance and protect myself, but I still felt the impact. Realizing that this would have already alerted half of the guards, I quickly went to the newly created hole and saw the waves crashing at the bottom of the prison and a gloomy atmosphere with dark clouds. Cutting my observation short, I transfigured the ledge and maintained the spell to keep myself from falling. I already felt the effects of the magical drain after everything I had done that day. I quickly summoned the hated figure.

"Kreacher," I called out.

"As the sole male heir remaining of the Black family, I summon you here."

Pop!

"Blood Traitor Master has summoned me," Kreacher replied with resentment.

I didn't bother correcting Kreacher's attitude and instead made sure to use precise language when giving him orders to prevent him from taking advantage of the situation, as he had done with Harry in the books.

"Take me back to the Black household, and then return here and throw all these bastards in the dungeons," I instructed Kreacher. "They have received news that you possess something belonging to the Dark Lord, and they were planning to retrieve it to prevent you from fulfilling Regulus's final order. You are only to take orders from me."

Stunned by my words and order, Kreacher was, most of all, shocked by my mention of Regulus's order.

"Hurry Up!" I yelled at Kreacher.

He approached me, took my arms, and suddenly I felt a pulling sensation in my gut. I stumbled to the ground and felt severely nauseous, like I was going to be sick, but I hadn't eaten much in the past week besides a few pieces of stale bread. I got back up and took in my surroundings, feeling the oppressive atmosphere of the house and the accompanying emotions of disgust and sadness that let me know exactly where I was. I looked around and saw a portrait of someone staring at me in shock.

Smiling at the now-stunned face, I said,

"Hello, my dear Mother."
