Harry Potter: Ero World

Chapter 30 – The Heir of Slytherin! Part-2

{Rigel's Room, Slytherin Dorm, Hogwarts}

{1st Sep 1991}

"You don't know anything about the Core expansion Ritual do you?" Daphne asked as she let out an exasperated sigh. This was the only reason she could see why Rigel revealed his bloodline trait.

"No, what's that?" Rigel asked, this had been one thing that had been bugging him ever since he saw it listed in her requirements. Why was a ritual listed there, it was one of the more important things he was concerned about.

"Alright, remember we talked about Rituals before how they had become extinct?" Daphne asked. Seeing Rigel nod she continued, "One of the Rituals that is still prominently used in our society is the Core Expansion Ritual. You belong to two bloodlines that are both pretty famous for having unique bloodline traits, Metamorphmagus and Parselmouth are two of the most unique traits you could have."

Rigel nodded, he knew about all this, "Yeah, I know the Parselmouth got a bad name because of Voldemort but it shouldn't be something so extreme that you had to drag me in here."

...

"Alright, you know Hogwarts is a pretty old school right?" Daphne asked which caused Rigel to shrug, he wasn't that interested in ancient history so he didn't know the exact dates and stuff.

"Well, it is. But even a school as prestigious as Hogwarts just educates under 30% of Wizarding Britain, with some of the students going abroad to study but more than 50% of the wizarding population is homeschooled. The reason that almost every other member in Slytherin is an heir to a small and large family is because most family only send their heir to gain connections while the rest of the members don't usually attend Hogwarts." Daphne continued, he still didn't see her point but he allowed her to continue as he nodded.

"The Core Expansion Ritual is another important reason the admittance rate of Hogwarts has increased. Early in the olden days, wizards suffered from too much inbreeding which not only caused complex situations while using magic but some other mental problems as well. The Core expansion Ritaul was a solution made for that, it allows someone who has never gone through a ritual before to merge their mana with another individual for a brief moment." Daphne explained as she waved her hands trying to describe the situation.

"So for a brief moment, the wizard or witch would have mana from at least two different lineages flowing through them which resolves most of the severe complications of the Inbreeding. Every old family has married into one another at some point or another as there are just so few pureblood wizards, the reason that most of us are sane is because of the Core Expansion Ritual." Daphne explained.

"I kind of understand what you are saying, but what's the problem with me revealing that I'm a Parselmouth?" Rigel asked.

"I'm getting to it," Daphne gave him an annoyed look and Rigel placed a finger on his lips.

'She hates getting interrupted when she is explaining something it seems.'

"There is a side effect of the Core Expansion Ritual, as the mana of another Lineage flows through you, there is a certainty of increasing your mana pool which is a welcome bonus, but there is also a chance of learning some family magic as the foreign mana leaves behind an imprint. That's why the inheritance ceremony is scheduled for the Winter Solstice after we turn 18. That way the heirs can safely partake in the Core expansion ritual without the risk of giving away family magic." Daphne explained.

...

"Huh, so why would I do the Core Expansion Ritual?" Rigel asked.

"Because every time you do the RItual you can get a 50-25% boost in your total mana capacity," Daphne explained.

"If this ritual is so good then why are you guys waiting for 18 years to do this, you surely could have increased your mana by a lot?" Rigel asked, he was taking into account that just one of the participants needed to be a Ritual Virgin.

Daphne blushed slightly as she explained, "It's because our core stabilizes when we turn 18, plus it's a sex ritual you can't do before 18."

"Huh... I was right on the mark with Virginity... so the sacrifice for this ritual is your actual virginity?" Rigel asked, if that was so then it would be difficult because he was quite sure he fucked Maria enough to not be called Virgin by any standard.

"No just no trace of wild magic in your cores, that is normally introduced into our body by Rituals," Daphne explained.

"I still don't see the problem?" Rigel asked, causing Daphne to look at him with a frown.

"Don't you find it weird that the Black Family and the Gaunt family are both almost extinct, it was because they didn't partake in the Core Expansion Rituals... ever. They were afraid of passing along their bloodline traits. Both the families started having complications, with the Black family getting afflicted by the Black Madness, and the Gaunt family's magic weakened so much that they were barely able to use spells." Daphne explained.

"I still don't see the problem, so what a few more witches would be able to increase their boob size, it looks like a plus to me," Rigel replied.

"So you are okay with someone else gaining the characteristics of Metamorphmagus or Parselmouth?" Daphne asked, her eyes widening showing her surprise.

"I'm not, a copy would never hold up to the original. You said that only a trace of my mana would be left behind right?" Rigel asked and Daphne nodded. "That's fine then, this might be the perfect tool for me to gain an advantage in the wizarding world. I can quickly ramp up my mana capabilities by doing the rituals again and again." Rigel shrugged.

Daphne pondered Rigel's answer as she looked at his face, the casual lack of his family's abilities that Rigel displayed was a good thing for her. That means her chances of getting access to the knowledge on bloodline curses would increase.

~Knock~ ~Knock~

A couple of knocks on the door broke up their short conversation as Rigel walked over to the door. He pulled out his wand from his inventory just in case and opened the door. 

...

...

"...I'm assuming you finished telling Rigel about the core expansion Ritual Greengrass?" Evelyn asked as she walked into the door and closed it behind her. "If so I have a proposal..."

AN - So any guesses on who's gonna be the first witch?
