Without the need for directions Orion headed to Sirius room.
As soon as Orion entered Sirius recognized him from the court trial and welcomed him warmly.
"Hey there, you must be the young genius Orion LeFay right? Nice to finally meet you" Sirius said politely.
"Hello Mr. Black, you look much better than last time" Orion said.
"Of course, thanks to that very hot mediwitch over there who takes care of me" Sirius said and geastured to an attractive woman in nurse uniform.
"Alright stop with the small talk. You are a slytherin so you clearly want something from me. I owe you a great deal and I will do my very best to repay my debt within reason of course within reason" Sirius said.
"Alright, let's get serious. You are correct that you can help me with a few things. First I want you to take guardianship of Harry Potter and train him in combat and dark magic" Orion said.
"Why would prongslett need that? He learns plenty at Hogwarts" Sirius said.
Orion just pinched the bridge of his nose and sighed.
"I know a lot of information even the unspeakables don't know. I will tell you what you need to know. Firstly, Voldemort is not dead. Last year he paratized our defense against the dark arts professor and tried to steal an Item in the school that would help him regain a body. Right now Voldemort is like a wraith but very much alive" Orion explained and told Sirius about Voldemorts fear of dying and the vague contents of the prophecy.
Sirius just listened to him with a shockened expression.
Orion then also explained about the horcruxes and Sirius face drained of all colour.
"That maniac! He split his soul? So when we eventually manage to kill him he would just come back?" Sirius asked still shocked.
"Yes that is the case"
"Hahaha oh we are fucked" Sirius just laughed in frustration.
"I found the location of two of them" Orion said.
"Regulus Black stole one of them, the amulet of Slytherin. It should currently be inside his room under several sealing spells. The other Horcrux was entrusted to your dear cousin Bella for safekeeping and is currently in the Lestrange vault" Orion said "I hope you can help me get them".
"Are you going to destroy them?" Sirius asked still processing the information.
"Of course not that would be a waste" Orion said and took out one of his favorite books about dark sacrificing rituals. He flipped to one page and showed it to Sirius.
The ritual described a ritual where one sacrifices the soul of a human in exchange for magic power. The stronger the human is, the more you gain.
"You can get into Azkaban for even posessing this you know?" Sirius said after reading the contents.
"As if your family library is any better" Orion remarked sarcastically.
"Urgh, I can only imagine what horrible knowlege is burried there. I was never much of a bookworm you know. Are you sure this works?" Sirius said and held up the book.
"Of course it's a grimoire" Orion said.
At that Sirius froze and looked down at the book. Grimoires were extremly precious ancient magical books that recorded knowlege of a whole organization or a very powerful wizard. Even the Black family as one of the most ancient house only had two of them.
"Alright, I can get the amulet but I don't know if I can acces the Lestrange vault" Sirius said and gave him the grimoire back.
"Well if you can't I'll just hire someone to filally rob this bank. Another thing, please don't tell any of this to Dumbledore. I don't trust him after all he as the caster of the fidelus should have known of your innocence yet he didn't do anything" Orion said and then took out another normal book about Occlumency. It was still a very rare and valuable book but still nothing compared to the grimoire.
"Learn this and also teach it to Harry. You need to learn how to protect your mind" Orion said and looked at him like an overmotivated teacher "Any questions so far?"
"To be honest yes a lot but I still need to process all of this" Sirius said massaging the temples of his head.
"I need to stay here for two more days, how about you come over to my house when I'm released?" Sirius asked.
"Sounds good" Orion agreed.
"The adress is number twelve Grimauld place" Sirius said.
"Alright, I'll see you then" Orion said and called his brother's house elf.
"Thank you, I'll see you in two days" Sirius said and watched as Orion got teleported back to Camelot via his house elf.
Orion reappeared in his experiment room where the floor was still full of weapon components of different rifles or guns.
With a wave of his hand he vanished all the mess and went to his table.
Now it was time to finally get rid of every motherfucking detection charm dumbledore put on the cloak.
He took out the silvery cloak that looked like it consisted of pure moonlight.
He then put it on the table and launched several analizing charms.
Sure enough the charm showed several compulsion and detection charms woven into the cloak that latched onto the cloak like parasites.
After an eternity of charmwork and analysing Orion was finally convinced that the cloak now was free of any tracking or compulsion charms.
"Oh the things I can do with this thing...Infiltrating the ministry, robbing Gringotts or assasinating some pureblood nobles behind their own wards" Orion grinned and looked at the cloak with excitement.
"Alright let's pull of my first heist" Orion muttered and made a detailed plan on how to get what he wants. His goal? Nothing more than the time turners in the department of mysteries. A pity that Hermoine won't be able to attrnd all the useless classes in school anymore. They also wont be able to save buckbeak but he honestly couldn't care less about it. If he had to decide between doing the morally correct thing or stea... ahm liberating the time turners from the incompetent ministry...well not a very difficult decision.
Orion then armed himself to his teeth with his enchanted combat suit and his new guns. Just in case...
With everything ready he took the invisibility cloak inside his ring and called for Flick to bring him to Hogsmeade. With a quiet pop he dissapeared and was in front of the three broomsticks in a second.
"Showtime" Orion said and went into the pup.
He would only need to use the floo to enter the ministry and then take a stroll to the department of mysteries under the invisibility cloak. Easy right?
