Y/N apparated to the East End of London, arriving in front of an upmarket looking apartment building, upmarket for the neighbourhood anyway. He pressed on the penthouse intercom button. It was quickly answered by a raspy high pitched voice which exclaimed:

"Unless you've got pussy or blow fuck off"

Y/N chuckled at the greeting:

"Is that anyway to say hi to your favourite little anarchist you ugly fucker?"

The tone of the intercom answerer immediately changed to one of happiness:

"Y/N, you little son of a bitch! I ain't seen you in forever. Your voice got deep! Get your arse up here!"

"You've gotta buzz me in you drugged up fuck. And my mother wasn't a bitch- she was a guttercunt."

Y/N heard loud laughing as he was buzzed into the building. He reached the top floor in a lift that didn't seem up to the journey and knocked on the door which was answered by a man with a tight open top and sunglasses who looked stoned off his tits.

"Y/N? The man asked looking upwards into Y/N's eyes. He momentarily scanned the early maturing teen's frame and exclaimed:

"Fuck you got big, boy! How you been?"

Y/N and the man bro hugged. It was Myron Wagtail, lead singer of the Weird Sisters, the most popular band in the Wizarding World.

"Good Myron, sorry for dropping in unannounced but I've had a unique anarchist opportunity come up and wanted to see if you were interested?"

Y/N was welcomed into the post party apartment that looked like a cliched rock stars pad, complete with sleeping naked groupies spread out around the large open plan living area.

"Bad time?" Y/N chuckled.

"Not at all mate, hey Kirley!" Myron called out to the shaven headed lead guitarist of the band.

Kirley's head popped around the doorway from another room and he nodded and smiled at Y/N before Myron continued:

"These flowers have wilted. Call the agency for some more."

Y/N rolled his eyes at the rock and roll lifestyle as Myron lit a smoke and lead Y/N out to the apartment's balcony:

"So what's this opportunity matey?"

Y/N smiled:

"I wanted to know if you wanted to help me with something- really embarrass the fuck out of that cunt Fudge, publicly?"

Myron took off his glasses and his eyes lit up. He was an anarchist at heart and this idea appealed to him in the best possible way.

"Fucking hell yeah. Why didn't Dean-O come and join the fun?"

Y/N chuckled.

"Dean and I, we aren't exactly speaking at the moment, Myron."

This revelation was met with a heart warming cackle from the punk rocker:

"You L/N's always was hard headed bastards weren't yas. If you weren't hitting someone you was hitting each other."

"Got me there man" Y/N smiled.

Myron had attended Hogwarts with Dean. Their friendship had shocked many- Myron was 3 years older and an anarchist. He once burnt down the dungeon in protest to Snape's ban on music in class. Dean was a rule breaker but much more uptight. Still they had clicked.

Y/N laid out his plan and Myron was ecstatic. In just under an hour they had everything in place- just the finer details Myron had to work out with his crew.

"Alright so when you need this for?" Myron asked excitedly.

"5th of February, so like- two months?"

"Piece of piss- I'll send you a bird a week before and then come here and get it, alright?"

"Awesome cheers man. I gotta go I'm supposed to be at school right now."

"Ha- my little fuckin anarchist. Fight the power Y/N!"

"Don't you worry Myron. I am" Y/N smiled. The two bro hugged and Y/N apparated to his next destination.

—~—

Y/N walked the streets of Knockturn alley. It was always dark here, even at two in the afternoon. He was greeted with looks between fear and respect and constant bowed heads.

"Grindelwald"

"Grindelwald"

"Grindelwald"

He ignored most of them. He was busy searching with his legilimency. He wanted to find just the right sucker.

He had been searching for about 20 minutes and hadn't found one yet.

"You're a pretend hard man"

"You're coming to my meeting"

"Meh- I've done much worse than you not you either."

He suddenly paused as he saw a man exit Borgin & Burkes and smiled menacingly.

Death Eater, blood purist, murderer- Y/N had found his scumbag.

He walked up to the man and stopped behind him, cleaning his throat. The man turned and spoke to the large figure behind him:

"Fuck of-"

Too late did he realise who he was talking to. The scumbag was thrown against a wall from a fiery explosion that smashed into his chest, singeing his shirt and knocking him out cold.

Dark witches and wizards emerged from all corners, all keen to see the source of the commotion. Most stopped dead in their tracks at the sight of the Grindelwald standing over an unconscious man. Terrifying rumours had spread far and wide among wizarding's darkest denizens about the Grindelwald. Y/N smirked at his audience sadistically:

"Leave. Now!"

They scampered and apparated, down to the last man and woman. Y/N chuckled, picked up the man by the collar of his shirt and levitated him. He opened a portal and stepped through with the unconscious body.

—~—

The man's name was Marcus Salcant, he was a veteran of the first war and had managed to keep off the Ministry's radar. His luck though had ran out as he woke groggily, unsure what happened. He looked around and realised he was in a dark dank cave when he panicked at his current predicament.

His feet were bound together, his hands bound above his head and he realised he had no mouth. He looked up at the person standing over him. It was the fucking Grindelwald.

He heard about Azkaban. It didn't take a genius to work it out. Someone doing that much carnage in Azkaban of all places, and then when it compared to what happened to Rosier. To Shyverwretch's store. All the other attacks.

Most whispers were saying this kid was the Punisher. Marcus was now sure of it as he felt his pants warm. He knew he was fucked. He looked up at the Grindelwald, unable to move or speak.

"Congratulations, Marcus" the man-child said in a sadistic cool tone.

"You're about to be of more use than you've ever been in your whole fucking life. You see I've got you somewhere. Somewhere very special- You don't need to eat here, you don't need to drink. All you have to do is think happy thoughts."

Y/N laughed before suddenly punching the man hard, breaking the Death Eater's nose. He turned and walked to the entrance of the cave.

A/N: Italics is Dementor's whispering to Y/N. Obviously Marcus can only hear a one sided conversation.

"Hey Dementor. I know you're here, come on out. You're not still sore about being brought here are you?"

A flapping was heard as the already cold and dark enclosure seemed to grow even colder and darker before Y/N heard back:

You trapped me here

"I saved you. Dementors are being killed out there."

You're the one killing us.

"Details. Don't sweat the small stuff, Grim"

Grim? Y/N heard back in a puzzled tone.

"Yeah Grim. That's your name now. I give all my children names. As you live here you are now one of my children."

I've never had a na- What do you want?

Y/N smiled:

"Truce. Peace offering. A deal"

What kind of deal?

"You help me teach someone the Patronus. All you have to do is hover far enough away for her to direct the spell but not be affected by you. Starting tomorrow."

And in return?

"I know you aren't satisfied by the natural nourishment in this place. I know your needs are sated, but you're not really satisfied are you?"

Go on...

"I've got a scumbag all gift wrapped for you in the cave behind me. No one else comes here and the cave doesn't face the entrance. He's all yours. Feed as much as you want. Just don't kiss him. Scumbags aren't an unending resource, not the way I kill them anyway."

Y/N chuckled at his own joke. Marcus urinated himself once more just at Y/N's words, even if the maniac was talking to himself.

I accept. I will not affect your person. May I feed now.

Y/N chuckled and stepped aside, holding his hand out.

"Go right ahead, you will find I am a generous and caring father."

As the dementor hovered over the murdering maniac Y/N looked back and thought to himself:

A partnership with a Dementor. Just when I thought life couldn't get any weirder.

He turned his Turner back to 11:30am and apparated to outside the Great Hall, scaring some first year Hufflepuff's he suddenly appeared in front of.

—~—

The rest of the day was nice and quiet, spent in the library working on assignments. Hermione would periodically stop and kiss Y/N, smiling at him with statements like "I just love you my Lord"; "I'm just proud of you my Lord."

It made Y/N hard as a rock under the desk. He couldn't wait to get his girl to the Room of Requirement that night.
