Sirius left the school and arrived outside the Longbottom’s manor. It was late in the night and the sky had begun to show signs of an incoming storm. The wind blew hard, the thunder crackled at times.
All rooms still bright? This late? Sirius surveyed from the outside. If nothing was wrong, he didn’t plan on going in. Where are the Aurors?
Quickly, he cast a disillusionment charm on himself and walked forward. With the storm suppressing his steps, he made quick strides and reached one of the windows without the curtains.
Not even a baby’s cry?
Carefully he slid up the window and entered the mansion. Keeping his steps light, he walked around and made his way towards the large hall.
“N-No! Leave Neville alone! Aaaargh!”
“Alice?!” Sirius let go of any semblance of covertness and ran into the hall.
Wand out, he leaped right into the open space and assessed the situation midair. Alice and Frank on the floor, struggling like a fish out of water. Three Death Eaters were present in the room—Rabastan Lestrange, Bartemius Crouch Jr, and Bellatrix Lestrange.
“Crucio!” Sirius hit them with the same spell they were likely using on the couple.
The Death Eaters were quick and returned Killing Curses instead. In that reply, Sirius did the same and struck them with the Killing Curses.
Bam!
Sirius’ chest abruptly exploded, carving a see-through hole in it. Yet, Sirius didn’t stop and kept shooting attacks. His immortality took them by surprise, it always did. Soon enough, Bartemius Crouch Jnr was hit and died on the spot.
Sirius avoided hitting Bellatrix as she stood with the baby in her arms, and other reasons. His sole focus changed to Rabastan. “Go on, join your brother, won’t you?”
Woosh!
The spells flung left and right. But Sirius was faster and deadlier for he didn’t fear death. His movements were bizarre like a beast jumping left and right and dodging.
“Avada Kedavra!” Sirius finally hit the last Lestrange man, ending the god-forsaken bloodline and house. “You! Give the boy back to Alice!”
Bellatrix stood there in shock, taken aback by Sirius’ threatening order. “Sirius ... It’s me, Bell—”
“You chose Voldemort over me.” Sirius cut her off. “If you want me to show even an ounce of patience with you, hand the baby back!”
Bellatrix, eyes wild with fervor, thrust the baby into Neville’s arms. In a swift gesture, she discarded her wand. “Even if I had desired to join you, Sirius, I couldn’t. The Dark Lord ... He commands total allegiance.”
“Now? Even now?” Sirius asked her, wondering if there was still some of that sanity left in her mind. At the end of the day, his motivation had forever been to protect his leftover family.
Bellatrix shook her head, her lips quivering. As if she wanted to say something but couldn’t.
“Unbreakable Vow?” Sirius asked her.
Bellatrix just nodded.
“Did you vow to the name ‘Lord Voldemort’?” Sirius inquired.
Bellatrix once again nodded.
Sirius chuckled a little. “Then the Unbreakable Vow is nothing but a snake without fangs. Voldemort isn’t his real name. His real name is Tom Marvolo Riddle! The vow is void from the beginning.”
“Tom?” Bellatrix exclaimed.
“Marvolo?”
“Riddle?” Frank and Alice Longbottom repeated the other two words.
“Rodolphus confessed to me before dying. I asked Dumbledore, and he affirmed it. Tom was a student of Hogwarts decades ago, born to a witch and a muggle.” Saying that, Sirius helped the Longbottoms up to their feet, making sure they weren’t too injured.
“Dumbledore knew?” Frank questioned in disbelief.
“For a long, long time,” Sirius replied and glanced at Bellatrix. “So, will you still return to your Lord? Or your family?”
Bellatrix let out a harsh breath and rubbed her face, moving away the curly dark locks of hair. She didn’t look very good to begin with, almost on the brink of insanity. “Home ... I want to ... go home.”
“Home it is,” Sirius said and walked over to her, extending his hand. “Just a little more and soon Voldemort will be gone too.”
“Thank you, Sirius.” Frank approached him with his son in his arms. “For everything. I know that you’re aware of the things so many wizards and witches say about you behind your back. They’re ungrateful, blind—I’ll never forget what you’ve done for all of wizardkind.”
“Just doing it to protect those I care about.” Sirius shrugged, looking at Bellatrix and thinking about his friends, Narcissa, Andromeda. “You two should rush to Hogwarts and hide there until I end Voldemort.”
“We will.” Alice quickly hugged him for a short moment in gratitude. “Be safe, Sirius.”
Sirius just nodded and clasped Bellatrix’s hand in his hand tighter, her flesh felt so cold. Then, he walked out of the mansion with her and apparated to 12 Grimmauld Place.
The very next morning, a special edition of the Daily Prophet was printed and sent all across magical Britain free of cost. The first page had the massive portrait of Voldemort along with a portrait of young Tom Riddle, taken from the school.
[The Real Blood Traitor! Lord Voldemort Is A Half-Blood, Investigation Reveals!]
With that title, nobody could avoid reading the page-long article written by Rita Skeeter, with the help of Sirius, of course.
It didn’t even require a deep investigation to find Voldemort’s roots. Soon, the story was openly revealed alongside a timeline—Tom’s mother, her seduction of a muggle with love potions, the birth of Tom, followed by the muggle father leaving his family. All the way to Tom ending up in an orphanage, then Hogwarts, and finally becoming Voldemort.
Of course, with Rita Skeeter’s brilliant mind, she was able to find a massive clue. The name Lord Voldemort itself had the letters that perfectly with Tom Marvolo Riddle, and the remaining three letters perfectly formed ‘I am’.
As soon as the readers read that line, even the non-believers became believers. Even the most staunch blood purists became enraged. Of course, so many of them had been curious about Voldemort’s background for years. The only clue they had was ‘Slytherin’s heir.’ But now, it turns out he wasn’t even a Pureblood.
During that same time, Sirius headed north to find Remus and get to the Potters as quickly as possible. Unless he was with the Potters, he couldn’t bring himself to relax for even a moment.
It was hard but not impossible. Where would someone like Remus live if he wanted seclusion? The only answer was a forest. There weren’t that many large forests up north. With Sirius’ animagus form, searching for Remus became easier.
Soon his search led him to Scotland. The land was so sparsely covered in trees that he found no trouble locating a small secluded shack in the middle of the Caledonian Forest.
It’s either him, or some old man. Sirius approached the shack.
Ting! Ting!
Fuck! Just as he took a step forward he noticed he had disturbed a thin thread at the feet level, jingling some bells. Smart.
“Who’s there?!” A voice shouted from inside the shack.
“Your father!” Sirius barked back.
The door swung open that instant. Remus came out, smiling ear to ear. “The wild dog returns home?”
“Home, but the hunt continues.” Sirius went ahead and gave his old friend a hug. “So Moony found himself a luxurious shack?”
“This is temporary.”
“It doesn’t have to be. I’m trying to find James and Lily. Dumbledore said you’re the secret keeper.” Sirius got to the point quickly, not having the luxury to delay anymore.
“I’m not the secret keeper,” Remus blurted.
Sirius frowned harshly. “Then who? No! Not him!”
“It’s him, Sirius. Even you didn’t expect it to be him, why would anyone else? We decided to change the secret keeper to Peter at the last moment,” Remus explained. “I’m just a decoy hiding here so all eyes are on me.”
Sirius felt uneasy just knowing that. He didn’t consider Peter as trustworthy as his other friends. Peter was a yes-man, spineless, and a coward, they had seen plenty of that over the years. Why he was in Gryffindor was itself a mystery. “And where is he?”
“Hiding just like me,” Remus revealed. “Don’t worry about it, Sirius. Dumbledore ensured the safe—”
“To hell with Dumbledore, that incompetent old sloth.” Sirius cursed openly. “He’s the reason we’re in this mess in the first place.”
“What do you mean?”
Sirius went on to explain everything, revealing all that he knew. Voldemort, his name, his background. Since newspapers couldn’t be delivered to the forest, Remus had no idea. But even the papers didn’t mention Dumbledore. So for Remus, the shock was bigger than normal witches and wizards. Furthermore, Sirius revealed that Voldemort already knew about the prophecy.
“I don’t trust his plans.” Sirius didn’t hide his doubt. “Help me find Peter, Moony. We have to get to James and camp in his house. I’ve killed most of the Death Eaters already, so not much is left even if we’re to fight face to face.”
Remus only thought about it for a moment. “If Voldemort knows the prophecy, then instead of hiding we should be preparing for a battle.”
“Exactly.”
“Let’s go then.” Remus swung his wand and all his luggage got packed on its own. “I have some idea where we might find Peter.”
Shhh!
“Master! Master Sirius!”
Out of nowhere, Kreacher appeared there.
What have I done! What have I done! No, there is still time!
Severus Snape rushed through the streets of London, looking for the house that he had never planned to visit in his life. His breath ragged, his face sweating, he ran like his life depended on it.
Only he can save them! Severus told himself and finally reached 12 Grimmauld Place. He knocked on the door quickly and soon was received by an old house elf.
“Master is not home.”
“Then call him!” Snape shouted. “If Sirius doesn’t hear me he will damn you to hell in fury! Go!”
An angry master was what all house elves feared. Not because of fear of punishment, but rather the fact that they failed at their duty to serve perfectly.
Kreacher, no matter how grumpy, was still a house elf. He saw no lies in Severus’ outburst and quickly vanished from the spot, appearing right where Sirius was. He quickly explained everything, grabbed his master and the friend, and returned.
“Sirius!” Snape shouted just as they returned. “S-Save Lily! Save her! Voldemort knows the prophecy! He’ll kill her ... He will!”
Sirius folded his arms, his expressions unchanging. “So it was you who weaseled? After all that I said to you that night. After all my warnings, you still bowed to Voldemort!”
Not a question but an accusation. Sirius could see it from Severus’ face that he had committed a grave mistake and was now crying over its possible consequences. His one-sided love for Lily was no secret to him.
“You knew?!”
“Kreachere, lock him in the dungeon!” Sirius commanded abruptly. “He’ll see the light of the day when the trials start. Remus, let’s go, we need to find Peter quickly.”
Severus didn’t even fight back and surrendered to the house elf’s magic, voluntarily getting locked. It was better than roaming outside.
“Where would a talentless wizard live?” Sirius wondered while walking with Remus in the Diagon Alley.
“He wasn’t rich,” Remus added. “But not starving either.”
Soon, they arrived at the Leaky Cauldron. But surprisingly they found the entire establishment empty. The bar, which was usually full of chatter, only had one single bartender.
“Where’s everyone?” Sirius approached.
“Oh! Lord Black!” Tom, the landlord, innkeeper, and barman exclaimed. “Of course, Of course! Who but you would dare wander this night of Halloween? May I offer some drinks?”
“Firewhiskey.” Sirius blurted and took a seat. “Why’s the place empty?”
“Oh, you don’t know? The word is that the Dark Lord will launch his biggest-ever strike tonight. Folks are scared, Lord Black. Nobody dares wander outside tonight,” Tom answered and slid a small shot glass of Firewhiskey to Sirius. “But of course, such matters don’t scare someone like you.”
Sirius and Remus were already frozen by then, wondering if Voldemort was planning to strike the Potters.
“Have you seen Peter Pettigrew? Short, fat, ugly, grubby skin, small watery eyes, pointed nose, and brown hair,” Sirius asked Tom. “He may have come to stay here.”
“Hmm...” Tom fell into thought. “I did, but he didn’t stay. He worked in the kitchen, and broke lots of dishes. So I fired him. Six months ago, if I remember correctly.”
Remus helplessly sighed. It was too far back for it to matter. “Any idea where he went after getting fired?”
“To hell!” Tom cursed. “He didn’t pay for them broken dishes! That ugly rat!”
Seriously? You’re calling him ugly? Sirius failed to take Tom seriously at that insult.
“Let’s go, Remus.” Sirius dragged his friend away. “If Voldemort’s gonna attack tonight, let’s camp at Godric’s Hollow. The moment the house gets attacked the charm will fail its purpose and recede.”
“But even then we won’t be aware unless he’s already inside the house. It’ll be too late, Sirius.” Remus warned.
Sirius understood and tried to think of a way. Can house elves cross into Fidelius charms? They’re pretty much immune to most of the human magical restrictions.
“What if we use Kreach—” Just as Sirius was suggesting something, he froze and gasped. Out of nowhere, a memory resurfaced in his head, as if a hidden door was unlocked and opened. “No!”
“He has invaded!” Remus roared.
Woosh!
Sirius didn’t spend a moment there and apparated away to Godric’s Hollow. This time he knew exactly where the house was. His heart pounded like a racehorse, his wand remained clutched tight in his fist.
“Voldemort!” Sirius roared and looked up, noticing a flash of light in the first-floor window. “Face me!”
Sirius had no idea what he did in that instant. His instincts took over and without realizing his body moved through the air, closing in on the window at rapid speed.
Boom!
He crashed into the closed window with his body, breaking the glass and the wooden frame. His eyes were bloodshot red in rage, no pain, no feeling reached his senses. All he saw, desired, and aimed to do was kill the Dark Lord.
“Avada—”
“Nooo!” Sirius heard the incantation from the dark hooded figure, his wand aimed at Lily who shielded Harry. “You can’t!”
Sirius apparated in that instant and appeared in front of Lily. With his hand, he grabbed Voldemort’s wrist so tight his nails dug into the Dark Lord’s flesh.
Boom!
The green flash still oozed out and struck Sirius point blank. But that didn’t change anything other than leaving a gaping hole in his chest, his heart blasted, making way for the new one to appear in its place.
“Die, fucker!” Sirius didn’t let go of Voldemort’s wrist and jumped forward, shoving him out of the window. “Avada Kedavra!”
Sirius roared the spell this time point blank, at Voldemort’s face of all the places.
“Aaaaaa!” Voldemort roared back momentarily before the Killing Curse hit him. He tried to fly away with his magic, but Sirius latched onto him like a Dementor sucking a soul. “Blood traitooo~”
“Just die!” Sirius roared and landed on the hard ground below, slamming Voldemort’s body under his elbow, cracking all the bones in the Dark Lord’s chest.
But Voldemort was already dead. The Killing Curse had done its work.
Shhhhh~
“What the—” Sirius jumped back suddenly as black steam came out of the dead body. It was hissing something meaningful.
“I shaaaal~ return~”
“Avada Kedavra!” Sirius once again threw a Killing Curse at the steam.
“Aaarh!” the mist cried.
What the fuck is this? Sirius cursed as the mist disappeared. Killing curse works on mist?
Sirius stood there for a moment, catching his breath, thankful that he arrived right on time. His heart had reformed, leaving a hole in his shirt. But he still felt out of breath. Seeing the dead body of Voldemort beside his feet brought pleasure, yet he couldn’t help but feel restless.
Peter betrayed us!
“Noooo...! James!”
Sirius looked up, hearing the distant cries from Lily. His heart sank instantly, guessing the worst. “James?!”
Sirius rushed back into the house, apparating in through the first-floor window. He didn’t find Lily or Harry there anymore and quickly rushed downstairs. Right at the bottom, he saw a glimpse of a lying body. The further down he went the more he saw, the more his heart sank.
“James!”
Lily’s cries mixed with Harry’s wailing. Sirius tried to hold his emotions and knelt down beside the body. There was no blood. Likely the Killing Curse was used.
Countless memories flooded his thoughts. The first they met on that train. I’m the worst friend someone can ever hope for.
“Sirius! Help him. Wake him up!” Lily caught his arm and jolted him. “Do something.”
Sirius placed his palm on James’s chest and shook his head. He was long gone, even before he arrived. Gone trying to protect Lily and Harry.
It all felt worthless now. All the battles he had fought, all the murders he had committed. What was the point when his best friend was the cost?
Why weren’t there aurors all over the village? Sirius asked himself, trying to make sense of things. Asking himself how this could have been avoided. Why isn’t anybody here even now?
“Sirius!” Remus finally arrived, bringing others with him. Silence fell on their lips as soon as they saw James’ body.
“Voldemort’s body is outside,” Sirius alerted them.
After that, all he could do was hold little Harry Potter and give Lily a shoulder to cry on. It was a strange life the three of them had lived. Where James was possibly, deeply in love, Lily’s stance had always remained mysterious. She even married James after claiming she enjoyed being with Sirius.
As for Sirius, he considered himself one crazy bastard. He hated his guts when it came to women.
Silently, he patted Lily’s back, trying to make her stop shedding tears. Harry had been agitated at first, but he soon fell asleep in Sirius’ arms.
“Come with me ... You need to gather yourself and take care of Harry.” Sirius helped Lily stand up after a few hours. James’ body had been shrouded in a white sheet by then already. “You need to be strong for Harry.”
As Sirius led Lily out of the house, he walked by Dumbledore. In his heart, he couldn’t help but hate the old man. Even after knowing everything he failed to protect the Potters. Was this an accident or the result of willful ignorance? For the prophecy?
As long as I’m alive, forget ever approaching Harry. Sirius held the little baby tighter in his arms.
Quickly after, one after another they all walked to the nearby graveyard and made the preparations. Many more wizards from the Ministry had started to appear by then. The news of Voldemort’s demise was spreading like wildfire.
Yet, there was no cheering.
By the time the sun rose in the sky and morning dew settled, the gravestone had been placed. Harry hadn’t stopped crying the entire time, as if he knew who was being put to rest.
“Lily.” Sirius stood beside her even after everyone else had left, leaving just the three of them there. “Come with me to my home for a few days. I can’t leave you alone here like this.”
She didn’t say anything and silently nodded.
So Sirius quickly brought the two to 12 Grimmauld Place. The interior of the entire building had been renovated and all the old portraits had been removed. So he didn’t fear it’d be too desolate, dark, and brooding for her and Harry.
Kreacher also received some threats about being thrown out and abandoned if he misbehaved with Lily and Harry.
Thankfully, Lily never had many run-ins with Bellatrix. So she didn’t fear when the curly-haired curvy witch appeared in the house and offered to help with Harry, or even hold a regular chat. It wasn’t that she had completely changed her views about blood purity, she just didn’t care about fighting for it anymore.
Yet Sirius found no respite.
He didn’t desire any rest. Much work was left to be done. Peter was still out there, so Sirius put an open bounty of ten thousand galleons on any information about him. Meanwhile, the Ministry started to arrest wizards left and right.
Sirius remained the spearhead during that whole operation as he knew the names of all the Death Eaters. While most had died at his hand, some were still left, such as Lucius Malfoy.
Weeks passed, and soon the number of detainees reached more than a hundred. The trials were held openly, filled to the brim with even journalists allowed inside. Even there, Sirius played a major role as he held the most evidence against the Dark Lord.
Many tried to get away by claiming to be under the Imperius Curse. But Sirius shut them all up by providing his own memories of his various encounters with the Death Eaters using the pensieve.
