Sirius stood at the center of the drawing room in Grimmauld Place, his face set like iron. Around him, the gathered members of the Most Ancient and Noble House of Black stood in grim silence.
Harry, thin and exhausted from his time at the Dursleys, sat beside him, his green eyes sharp with wariness. Hermione stood next to him, practically vibrating with rage.
Sirius’s wand pulsed with raw family magic as he called upon the ancestral power that ran through his veins.
"By the blood of my forefathers, I summon the House of Black!"
A pulse of magic shot through the manor, stretching across the wizarding world, demanding the remaining Black family members to return home.
And they answered.
Narcissa Malfoy arrived first, sweeping through the doorway, her sharp blue eyes landing immediately on Harry.
Her expression hardened. "What has that old fool done to my Heir?"
Andromeda Tonks followed moments later, her hands already tightening around her wand.
Even the shadows of long-dead Black ancestors whispered from the portraits, murmuring in approval.
Sirius turned to his mother’s portrait. "Bellatrix Lestrange is no longer a Black."
Walburga Black tilted her head, her smirk cold. "Then she is nothing."
A snap of magic burned Bellatrix’s name from the family tree.
And just like that—she ceased to exist to the House of Black.
Then—
The doors burst open.
Albus Dumbledore stood at the threshold, the Order of the Phoenix gathered behind him.
His blue eyes darkened. "Sirius, this is unnecessary."
Sirius smirked. "I don’t take orders from you, Albus."
Dumbledore stepped forward. "Harry belongs with—"
"Don’t you dare finish that sentence," Hermione spat, her wand already raised.
"Miss Granger," Dumbledore sighed. "You are letting your emotions—"
"NO, I’M LETTING MY RAGE!"
And then Hermione attacked.
There was no warning.
There was no moment for the Order to prepare.
There was only chaos.
"Deprimo!"
The ground exploded beneath the Order, sending Kingsley and Arthur sprawling backward.
"Expulso!"
A shockwavehurled Moody through the doorway, his magical eye spinning wildly.
"Ventus Atra!"
A cyclone of raw windripped through the hallway, slamming Ron into a wall.
"REDUCTO! STUPEFY! BOMBARDA! IMPEDIMENTA! LEVICORPUS! EXPULSO! FLIPENDO!"
The spells came one after another, nonstop, unrelenting.
The Order never had a chance to fight back.
Hermione moved like a storm, her wand flicking so fast it was nearly blurry, her feral grin widening every time someone screamed.
Ron tried to crawl away.
"DEPULSO!"
Hermione sent him flying into Molly, the two crashing into the floor in a heap.
Moody growled, pulling himself to his feet—
"EVANESCO!"
His staffvanished from his hands.
"EXPELLIARMUS! DIFFINDO!"
Kingsley’s wand ripped from his grip, the sleeves of his robes slashed open.
"FINITE INCANTATEM!"
The anti-apparition wards collapsed, leaving the Order trapped.
"NO MORE CONTROL, DUMBLEDORE!" Hermione shrieked. "NO MORE MANIPULATION!"
Narcissa Malfoy was suddenly at her side, her wand flashing like a silver blade.
"Do hold still, Weasley, I’d like to aim properly," she murmured with a savage smirk, before sending a whip-like spell that lashed across Ron’s chest.
And then—
"BLOOD TRAITORS IN MASTER’S HOUSE!"
Kreacher appeared.
The ancient elf stood, his wrinkled fingers wrapped around a massive, gleaming elven battle-axe.
"KREACHER SHALL REMOVE THE FILTH!"
Molly shrieked as Kreacher charged, swinging his axe at her feet, forcing her to scramble away.
"STOP THIS!" Dumbledore roared, his wand finally whipping forward—
Sirius smirked. "Finally."
The duel between Lord Black and Albus Dumbledorebegan.
Sirius and Dumbledore clashed, their magic flooding the air.
"You are making a mistake, Sirius!"
"No, you made the mistake when you hurt my godson," Sirius shot back.
The walls shook.
The House of Black awoke.
"Sentinella Domus, excita et defende!"
The wards roared to life, shadows lashing out like living tendrils.
Dumbledore barely had time to react before the very walls of Grimmauld Place rejected him.
The Order fought, but they were outnumbered.
Narcissa and Hermione fought back-to-back, their spells merciless.
Kreacher’s axeswung, forcing Moody to dive out of the way.
And then—
"ENOUGH!"
Sirius’s voice boomed, shaking the chandeliers.
The Order froze.
The walls shuddered.
"This is the House of Black," Sirius declared. "And you are no longer welcome here."
The wards flared.
The Order was ripped from the house, hurled onto the street like discarded waste.
Dumbledore reached for his wand—
But the house struck him down.
The doors slammed shut.
The house sealed itself against them forever.
Inside, silence fell.
Harry exhaled slowly, looking at Sirius. "So that’s it, then?"
Sirius chuckled darkly. "That’s it."
Hermione was still breathing heavily, a wild grin on her face. "I am never going back to Hogwarts," she declared.
Sirius snorted. "You don’t have to."
Narcissa smirked. "I must admit," she said lightly, "Miss Granger is my new favorite person."
Hermione grinned. "Likewise, Lady Malfoy."
Sirius turned back to Walburga’s portrait, his expression unreadable.
Walburga Black tilted her head, her lips curving.
"Well done, Lord Black," she said smoothly, her sharp gaze shifting to Harry. "*And welcome home, Heir Black."
The magic of the house shivered, wrapping around them both.
For the first time in centuries, the House of Black had truly risen.
