The plan called for a start in the dungeons, with the Order working their way up to finally meet Hermione and Draco in the ballroom. They worked in tandem, advancing deadly like pairs of big cats. Silent, they stunned all the death eater guards they met. Some of the Order were particularly nasty. Ginny caught Mad-Eye throwing a particularly vicious spell which exploded on his opponent's right side. The death eater would be burned for the rest of his life, Ginny was sure of it when she saw the skin melt. She saw Mad-Eye's slow smile and nodded her approval. They might not kill all of them, but they would make sure they'd mark all of them for who they were.

Bill and Flitwick were opening the dungeons doors one by one, casting Silencio and preventative stunners before moving to the next. The newest Furies followed, swiping the cells. Ron and Neville on one side, Blaise and Padma on the other, and Luna at the center, straight and luminous as a lighthouse. They sent every prisoner they found to Poppy immediately with portkeys Malfoy had blessed to exit through the wards. Most of them would survive, even if the path to recovery might be long for a couple of them. A couple were too far gone. In one of the rooms, they found two women, harnached to operation tables. Magic maintained them in a semblance of life, and the smell of their bodies made Neville retched.

One had her head split open, and her brain was visibly missing two chunks. Both her legs had been amputated. The other woman was split in the middle, her thorax opened like a car trunk. Her chest looked empty without her lungs and her spine, floating in littles jars near her while her whole body trembled. Luna approached and looked in their eyes, but nothing of them remained. They were mere windows, open to an ocean of pain. The Hogwarts students quickly ended the women's lives. They turned to the death eater stunned in the corner of the room, his pants down to his ankles. The butcher died a little bit slower under the five wands.

With the dungeons clean, it was time to move to the ballroom for the final show. The Order was now waiting at the door, Severus sending his last signal to Hermione.

Ginny raised a steady hand. "Give me the ring and the dagger." She looked at the ring, already weak from Dumbledore's attacks. It still held Tom's last piece of soul, and Ginny was ready to give him back all the pain he had gifted upon her. She raised the knife, and tore into the ring. The lights went off under the surge of power. In the ballroom, the dark lord screamed, and all hell broke loose.

Hermione and Draco triggered the dormant spell, and a bubble appeared around the young death eaters. The blond heir tutted, unimpressed, "No one has ever warned you about ritual circles? How unfortunate…" The first idiot who touched the bubble flew back to hit his back on the other side of it. He laid unconscious, a good reminder to the others that they should have studied a bit when they had the chance. Ron, Neville and Luna posted themselves in close proximity, stunning the death eaters one by one before entering the bubble with the counterspell Hermione had developed and taught them last month. Removing their masks one by one, they executed the plan as agreed. If the young person behind the mask was a member of the Sacred Twenty Eight, they were to be disposed of. After all, you couldn't let them get away and continue the dynasties who had so much power on their entire society. Corrupted power didn't need a slap on the wrist. Corrupted power needed to be destroyed. The rest were maimed of their wand hand, stunned and shipped to the Ministry. They would spend the next 25 years in Azkaban, enough to change society without their intervention.

The Weasleys twins were running wild in the ballroom, deflecting spells in explosions of colors. Their opponents didn't understand the joke was on them. Distracted by the chaos, they always missed Bill and Flitwick right behind the twins, and their bodies fell one by one. Most death eaters only scanned their whereabouts at eye level, allowing the part-Goblin to come lethally close to them. They would regret this lack of vigilance if only Flitwick kept them alive. But the professor had seen enough in the dungeons. He finally understood the Furies, and tonight, he only had one goal: to burn it all.

In the middle of the chaos, lord Voldemort was fighting the fight of his life. Yet, despite all his power, he couldn't get rid of the swarm of annoying bugs attacking him. In front of him, Harry Potter threw Sectumsempra after Sectumsempra, soon joined by the traitor Snape. Voldemort easily deflected the spells, laughing like a maniac. He would show these peasants he was more powerful. Their spells had no elegance, no thought behind them. They would realize their mistakes when they died with their internal organs melting slowly. He raised his wand, elegantly waiving a complex pattern, when a ball of fire attacked him from this side. He turned to see a redhead, probably one of those blood traitors. The daughter it seemed. So young and innocent.

His smile turned dark. The slicing spell sent by Draco his way threw him in an expected bloody rage.

As the dark wizard fought against so many enemies, the noises grew quieter around the group. Soon enough, all dark opponents were either dead or in the Ministry's cells awaiting trial. The dark Lord grew more and more frustrated, and with it wilder and wilder. He didn't notice when Charlie summoned the cauldron behind him, protected by Vector's cloaking spell. Mad-Eye threw a Bombarda at Voldemort, Molly Weasley and Remus jinxing his legs. He stumbled, and fell in the cauldron, gasping for air as the slimy mixture felt like it was solidifying around him.

Soon enough, he couldn't move anymore, and saw a sea of eyes looking avidly at him.

For the second and last time of his cursed life, Tom Jedusor was gripped by the fear of losing his life. All wands pointed at him, and the room illuminated a vibrant shade of green with the combined Avada Kedavra who claimed Tom Jedusor's final life.

An uncertain voice broke the stunned silence that followed. "What do we do now?"

"What do you mean, Weasley?"

"Oye, first of all, you can't call all of us Weasley if you're dating our sister. Start learning our names, Malfoy," started George, letting Fred finish their thoughts. "Second of all, what do we do? There's a lot of dead bodies here...How do we make sure, erm, that they remain dead?"

"See, George, I'm not dating your sister. I'm officially courting her. And second, you can burn this entire manor for all you want. We could use a rebuild. What do you say, Harry, Red?

A new home for a new family?"

Harry smiled at the man he loved, and crushed him in a loving hug. They were soon joined by the petite redhead. Harry started, with a raspy voice already breaking,"Draco, your mother-"

"I knew when I didn't see her back with Bellatrix during the fight. I should have killed my aunt a long time ago."

"It's not your fault, Dray," soothed Ginny."Bellatrix killed your mom because Bellatrix was a bloodthirsty monster. She killed her own blood, and deserved her fate. I'm sorry we failed you and couldn't save your mom."

"She knew what I was doing, you know. I saw her observe me and Hermione a couple of times, just for her to nod her head in approval and never utter a word about it."

Harry wiped Draco's tears," Let's give her the goodbye she deserves."

As they walked outside of the garden, Draco was the first one to wipe his wand and conjure the Fiendfyre. Soon followed by each of the fighters, they watched the manor get wiped out with the flames, leaving not even ashes. Nothing of it remained.
