A/N: More violence.

Y/N had been out of the Hole for four days. It had taken him twenty four hours to shake off the after affects of his torture, but once he had he was straight into business again.

He'd entered Azkaban with three targets-
Antonin Dolohov, Augustus Rookwood and Thorfinn Rowle. His father's murderers. His torturers. He was going to get vengeance.

He was now imprisoned with them. Or, as he had reminded the crowded mess hall on the first day, they were imprisoned with him.

Dolohov was a difficult target to get at. He was in D wing, where the most insane inmates, the ones who had acted out the most, were located. Sirius had been incarcerated there. Y/N would have been relocated there after his 'dispensements', if he'd been given a longer sentence. As it was his remaining two targets were located with him on C wing.

It gave him opportunity. It gave him time. He'd been stalking his targets for the last three days, watching, observing, noting, preparing. Studying his targets, their routines. He was ready to make his move.

In his cell at night Y/N had been experimenting. The anti-magic wards didn't allow him to cast external wandless spells, but any internal magic that was cast through sheer will, rather than an incantation, that worked fine. His human transfigurations worked fine.

There was something in hunting called the Hunter's triangle. When establishing what needed to be hunted down, whether it was man or monster, the three factors that needed to be assessed were means, motive and opportunity.

Y/N had the motive. Y/N had the opportunity, and now Y/N had the means. It was time for vengeance.

Everyday at 10am following breakfast there was a lockdown of the cells. Everyday the guards of C wing didn't check halls 1 and 3.

Hall 1 was where Y/N and Jackson were located. So was Augustus Rookwood.

Thornfinn Rowle was located in 3. It was his private hall. His gang, the Pureblood Brotherhood, occupied the cells on the block, insulating Rowle from attack. Every morning Rookwood would visit Rowle.

As stated, Rowle was leader of some gang called the Pureblood Brotherhood. Most of the important Death Eaters in Azkaban had formed their own gangs when they were sent here, apparently being a Death Eater was something respected in this hellhole.

This particular morning 'Rowle' had stopped Rookwood in the passageway, told him he would visit Augustus's cell that morning instead. Rookwood had nodded and taken the bait.

—~—

Rookwood was sat in his cell, waiting patiently as Rowle stepped in and closed the bars behind him.

"About time you got here Thorfinn. Now what are we going to- ahhhh!"

Rookwood had screamed as he was pounced on, his left arm grabbed and bent backwards, snapping at the elbow. His right was quickly left in the same condition. He whimpered and cried as Thorfinn shimmered and went wavy before turning back into Y/N.

Y/N held the smaller Rookwood against the wall of his cell, ripping him up by the hair and pulling a knife from Rookwood's bed.

"Augustus, Augustus, Augustus.... you must have known this day would come. I'm going to kill you Augustus. You're going to die!"

Y/N snarled, holding the knife against the former Unspeakable's chest as he continued:

"But first we're going to play a game. It's an easy game Augustus. All you have to do is bleed. How much can you bleed for me?"

Augustus screamed as he was pierced, the knife cutting deep into his flesh, blood pouring from his wound.

Albus Dumbledore was sat at his desk preparing for the coming school year when he jumped suddenly.

A roar ripped across the skies above, the loudest thunder he had heard in his more than a century of life. He walked briskly to his office window and was shocked. He had thought to himself earlier that morning how beautiful the sky had been, clear and blue, a beautiful late summer morning.

The sky had gone black, seemingly out of nowhere, and torrential rain began to fall.

—~—

Hermione and Lavender had been sat in the Granger backyard enjoying the early morning sun when they had jumped at the loudest noise they had ever heard. The sky had blackened from nowhere and the two girls ran inside to avoid the torrents of rain which suddenly fell.

—~—

Cornelius Fudge was stood looking fearfully out of his office window. Thunder had always scared him. He looked at the face of the beautiful woman next to him.

"Lilith, my dear, I don't think I've ever seen you so happy."

Lilith turned and smiled at Fudge, saying with a giggle:

"What can I say? I always liked rain."

—~—

Rookwood had screamed and cried and babbled as he bled. He had bled so so much. He had tried everything to save his pathetic hide, to end his torment. He had cried like the coward he was. He had begged Y/N to spare his life, babbled some nonsense about the Knights of Merlin.

Y/N was too far gone with bloodlust, pulling the man's head back and stabbing him through the throat.

He stared into Rookwood's eyes as he died, the last thing the former Death Eater saw was Y/N's pitch black eyes staring back at him.

—~—

Y/N walked silently into hall three, blood soaked on his arms. The gang members in the hall looked from their cells puzzled, wondering why Augustus Rookwood was covered in blood.

He reached Rowle's cell and the smaller blonde man turned around.

"Took you long enough... what happ-"

In a moment Y/N had pounced, dropping his human transfiguration and stabbing Rowle deeply in the stomach. The whole gang was around them, he had to be quick.

Rowle gulped and chuckled, grabbing hold of Y/N as the blade was dug further into his vital organs:

"You've got bigger boy. Do you still squeal like a pig? You squealed so loud when you were a baby"

Rowle mocked as blood leaked from his mouth, a final deep slice from Y/N spilling his intestines on the floor. Rowle dropped, deceased, and Y/N smiled sinisterly as he turned and left the cell.

He quickly walked to the end of the hall but noticed something was wrong immediately. The door leading to Rowle's hallway was locked. A dementor flew down into view and Y/N whispered instantly, commanding the creature:

Open the door

He suddenly heard a number of cell doors behind him open, the prisoners walking out and mumbling. Y/N turned back around to the dementor.

Open the goddamn door

...You should have fed us...

The dementor replied before it flew off. Y/N turned to look at the gang members filling the hall. It was go time. He inhaled deeply as he heard:

"Holy shit the kid killed the boss"

"Let's get him"

"Let's go cmon let's go"

Y/N started yelling to himself: "Ugggh ahhhh!"

Breathing heavy.

Getting the adrenaline pumping.

Fight or die.

Again.

Time to fight.

Y/N charged towards the approaching gang members.

A/N: Gang members given numbers, easier to track.

Y/N quickly punched one in the face, dropping him to the floor, and grabbing two by the arm. Y/N pulled him down as he ducked under three's swing.

Still keeping hold of two, Y/N knee'd him in the stomach hard, knocking the air out of him. He threw him to the ground before turning around and taking hold of three, headbutting him and grabbing his weapon.

It was a broken pool cue that had been sharpened to a point. Y/N threw three to the floor and stomped on his neck before sidestepping four and slashing his stomach, charging again towards five.

Y/N raised his left arm to take the blade that five was thrusting towards him. It stabbed deep into Y/N's outside forearm causing him to grunt loudly in pain.

Y/N though did what he did best. What he did like no other. He pushed through the pain of it, impaling five through the chest with the pool cue. He pushed five into a cell while he desperately tried to pull the blade from his arm.

He got the shiv loose as two punched him in the face from his right, causing him to fall to the ground and stab four multiple times in the chest as he got up.

Y/N got to his feet quickly as two fell over his gang mates corpses and six charged him. Six was stabbed first in the groin, then the chest then the neck and shoved into an open cell.

Y/N turned back to two, impaling him in the chest with the blade before lodging it in the side of two's skull and shoving his dying body into another cell. He turned back around as seven charged him.

He dodged seven's blow, punching him in the stomach. As seven bent over in pain Y/N got him in a front face lock, his arm around seven's throat. Using all his strength he squeezed and lifted until he heard a snap and seven's body went limp. He dropped him as eight and nine came lumbering towards him.

Eight was punched in the throat before having his neck snapped.

Nine was big, bald and held what looked like a homemade tomahawk. He swung for Y/N's head. Y/N ducked and used his momentum to bring nine to the floor.

He punched nine in the face again and again and again until he released the tomahawk. Y/N quickly grabbed it, roaring in rage as he brought the tomahawk down, smashing in the top of nine's skull and killing him instantly.

There was just number ten now. Y/N was quickly kicked in the face knocking him backwards and into the wall.

Ten punched him twice in the side of the face as Y/N pulled himself to his feet. Ten was much larger than Y/N and started to choke him. In response, Y/N drove his thumb into ten's eye socket as hard as could, causing the larger man to scream in pain.

Ten pushed Y/N to the floor, Y/N falling on his back, desperately reaching for the blade behind his head as ten picked up a blade of his own and stalked towards Y/N.

Y/N reached the piece at the last second and as ten reached him he kicked ten in the balls as hard as he could.

Ten fell down on top of him in pain but was caught by Y/N, who sliced his throat, ten's blood splashing all over Y/N's face and upper chest. His heavy corpse then fell on top of Y/N, who grunted in pain, surrounded by corpses of the men he had just slaughtered.

He pulled the heavy corpse off himself and stood, covered in blood. He looked at the dementors, who were hovering at the end of the hall, in as much shock as a dementor could demonstrate. Y/N heard their whispers:

...No. What has he done...

...Put him in the hole...

...We should give him the kiss...

...We aren't permitted...

...He has cost us enough food...

...Throw him in the hole until he leaves next week..

Y/N smiled to himself as one of the deathly cloaks flew towards him. Two down. One to go.
