Harry Potter: Ero World

{Diagon Alley, London}

{23rd June 1991}

"...Are you sure you would be fine on your own, you could stay with me..." Minerva spoke as she looked at Rigel, he was putting all the extra books that he had bought into his trunk.

"No, I got it, it's just for a couple of months before I move to Hogwarts, plus I already have a place lined up," Rigel replied. Although living with her hot ass sounded tempting he has a sub-system that is geared toward more sexual acts, and other than admire her figure he won't be able to do much of anything in her home.

"Alright, see you at Hogwarts then Mr. Black," Minerva spoke with slight hesitation in her voice before she apparated away. 

Rigel took a deep breath as he sighed, the day had taken its toll on him with all the walking and shopping, thankfully he didn't have to buy his potions supply so that was something. While stuck on a chair he had also thought of a simple plan so he walked back toward the Leaky Cauldron.

While he could have lived in the motel service the Leaky Cauldron provided, he wasn't sure about their security protocols. Rigel dragged his suitcase and walked through the pub without any interaction. The first thing he noticed was the lack of color. Well, his eyes noticed the cars, while his mana sense noticed a lack of spark in everyone. The car's looked like something straight out of a time-travel story. They were a lot more boxy in shape with perfect corners and straight edges the norm. 

He also noticed exactly where Muggles were different from the wizards, they didn't have mana flowing throughout their body like little currents. The buildings were not etched in runes that not only supported the wacky designs that wizards could come up with but also replaced electricity.

'I can't wait to get my hands on a smartphone, please tell me Jobs is alive and well in this world...' Rigel thought, while he didn't believe in the modern-day iPhone, Apple was the first one to push the limits of smartphones at least from what he could remember. 

'But then again, muggle money won't matter in the wizarding world.' Rigel thought. The world he was in was different than canon. In canon muggle-born not only had free tuition, but they also could use pounds to exchange for Galleons. He asked Prof. McGonagall about changing some of his galleons into pounds but apparently, they don't do that here. 

'It was likely a way for them to trap Muggle-born into accepting the loan terms for their Hogwarts education and then trap them later...' Rigel concluded. While he hadn't seen obvious signs of slavery right now, the Ero-Edition name didn't give him any confidence.

The backwardness he had gotten used to in the Wizarding world was a lot more apparent in their architecture. In the Muggle world, the architecture was more modern but the technology was a couple of generations backward. He looked around and noticed that the clothes that people wore were a lot longer with Jeans and T-shirts being the primary casual choice.

He kept walking until he found a nice and quiet alley. The alley was dark and deep and try as he might he was not able to make out if anyone was in there. This was the perfect place to end the trail, he opened his inventory and pulled out Narcissa's robe from it. 

The cloth was enchanted with several runes and Rigel was willing to bet one of them was a locator spell or something similar. He dropped it on the floor and after a final look around softly whispered, "Kreacher!"

~Pop~

An audible pop and with a whirlwind a wide-eyed house elf appeared in front of him. He was short, barely reaching 2 and a half feet in height, he was bending a little but his eyes bulged as he stared at Rigel. The peace and quiet of the alley didn't last long as Kreacher threw himself at Rigel's feet and started sobbing.

"M-master Regulus... N-no master died... but mana... so similar.." Kreacher mumbled in broken English as Rigel looked around at the alley, he didn't have time for this so he hoped his commands would work.

"Kreacher shut up!" The wailing elf Eeped as his voice instantly went from 100 to 0.

"Back up 2 feet..." Rigel continued, the elf hopped back two feet but he was still leaning forward toward Rigel.

"You are not allowed to talk, just nod your head yes or no," Rigel spoke and the elf nodded his head so fast his ears flopped around.

"Good, now how many properties of the Black Family do you know of?" Rigel asked. The Elf immediately pointed his finger upward and signaled 1.

'Huh, I was expecting a lot more but I guess this will have to do,' Rigel thought.

"Grab my hand and take me there!" Rigel commanded as he extended his hand to the bobbing elf. Kreacher nodded as he hurriedly grabbed onto Rigel's hand with his left hand and snapped his finger with his right hand.

{12 Grimmauld Place, London}

{23rd June 1991}

Rigel stumbled at the abrupt nature of the journey. He took a moment to stabilize and was immediately assaulted by mana as his mana sense overwhelmed him. A blanket of mana enveloped him and it stayed there for a few moments, judging him before it vanished and he grabbed onto the dining table for support. 

'Okay Note to Self, breaching into the stronghold of an Ancient House isn't a good idea...' Rigel questioned as he closed his eyes, his senses extended and he was blasted with several colors that covered the whole house. 12 Grimmauld Place was a 3-story house and it was completely covered in several colored blankets of mana that were connected to a large glowing stone somewhere on the first floor.

'The ward and the wardstone...'

Rigel opened his eyes and looked at Kreacher, "You are only allowed to answer questions I ask, now tell me, where is my Great-Grandfather?"

The Elf's years visibly dropped as he hiccuped and replied, "L-Lord Black died earlier last month." 

'Huh, impressive timing, though I could have used his help to ban Narcissa and anyone else from connecting to this place...what about the rest, the story didn't cover much about them other than their abusive nature.' Rigel thought.

"What about my Grandparents?" 

The questions were missed by further sobs as Kreacher spoke continuously for the next 2 minutes spinning the tragic tale of the death of Orion and Walburga Black.

'Alright, this is good, So I have no restrictions for now. Now let's see if I got the vibes correct about the Malfoy plan to take over the Black House wealth.'

"Who is added to these wards, can Narcissa and the rest of the Malfoy come here?" Rigel asked.

The house-elf had a strange fond look on his face as he replied, "N-No, Lord Black blacklisted Mistress Cissa from the wards... She had been hoping to visit but could not until the end of this year." 

'Huh, Narcissa charmed Kreacher, I do need to take some precautions just in case.' Rigel thought.

"Alright, you are forbidden to leave this house and contact anyone other than me until further notice... now go clean Father's room and slowly start cleaning this place... also take down all the portraits in the house and place them on the dining table," Rigel instructed, the elf nodded as a look of satisfaction appeared on his face as he popped away. It looks like he liked being ordered around.

'Now that my safety is okay, I need to focus on learning magic and getting my LP points up...'

His eyes darted toward the corner of the room where he saw someone move only to come face to face with his own reflection. He had been in so much hurry that the fact that he didn't know what he looked like didn't cross his mind.

'Well, I know this face would do good with the muggles, and in the domination system it never said that LP could only be earned through sex with witches...'
