Harry Potter: Ero World

{Library, Hogwarts}

{4rd Sep 1991} 

{3rd Person POV}

The spell description was enlightening and Rigel could see himself using it in the future, but it didn't help him in his current scenario. The premise of Illusion magic was interesting though because sound was an integral part of an illusion to be real.

He closed the book and looked at Hermione who was giving him a questioning look, Rigel read it as she was inquiring about the book and he nodded. "This should have what I'm looking for, hopefully..." Rigel responded and then he began walking back to the table that they were occupying. 

He sat down to read a book and after a brief moment of hesitation, Hermione sat down as well. A brief moment of awkward silence existed but as he got engrossed in reading the book he could sense that Hermione picked up the book that Daphne had left behind in a hurry and began reading.

...

Romancing Hermione was bound to be slow, so instead he focused on the book in front of him. Illusion magic was a branch of magic that was never focused on in the book or movies. Why? He couldn't answer because thinking about him being in a fictional world kind of nudged his existential crisis... slightly.

Nevertheless, the number of spells mentioned in this book was pitifully low and all of them were niche charms that had no use case, at least none that he could think of. Some could be useful but any type of lingering magic could be detected by him and since he could do it, he was pretty sure that there would be things like magic sensors or something in the world. But they would work in high-speed combat so the field has some research purposes.

...

'What would I even do with a spell that hides a door into the surroundings? This branch of utility magic kind of reminds me of Genjutsu from Naruto. They both seem powerful on paper, trapping the mind and visual senses but in reality, they are bad against powerful individuals. They would work well on unprotected minds but not against real threats... Then again I should learn the spells just in case and theorize after.' Rigel concluded.

The only good thing in the visual section of the spell was the Glamour charms, sure someone might be able to detect their existence but no one would be rude enough to point it out or try to dispel them. These spells would make it increasingly easy for him to venture into the muggle world when he needed it later because although the movies and the books kind of ignored the biggest pothole in the wizarding world, he wasn't going to.

'For a seemingly smart witch, I never could reason why Hermione never suggested using guns. One click from far away with a nice scope and Voldemort would have a nice hole in the middle of his forehead...' Rigel thought. A nice gun... smuggled, or stolen from one of the gangs and he would have it stored in his inventory. For emergency purposes.

Unless there were some magical bullshit like gunpowder doesn't work in the presence of magic, he was going to get a gun at the end of the year. Yeah, it was pretty easy to stop projectiles with a simple shield, but you have to be fast enough to get the shield in the first place.

"You okay Rigel?" Hermione asked as she nudged him slightly, he had been staring into thin air while silently shaking his head.

"What?... oh yeah, I was just thinking about the spells in the book," Rigel responded.

"So what do you think?" Hermione asked, she was curious to see what insight he might have.

"Well, I kind of don't understand the author's dismay about Illusion magic being an almost extinct branch of magic. Because truthfully this type of magic is quite cheap and unless the illusions could affect the mind of the targets, it is simply an Optical Artifact which is kind of useless. I have more hopes for the auditory illusions because audio, being a byproduct of the vibrations could more realistically be faked... or maybe the author doesn't have access to actual illusions which work by manipulating the nerve impulses in the brain..." Rigel spoke.

Hermione's eyes brightened at Rigel's insight into physics and basic biology, she liked how he analyzed magic which completely, which completely defied the laws of the universe she was familiar with with logic and reasoning the after-effects with the same laws that magic defies. She couldn't help but question, "You are applying physics to Magic, isn't that kind of redundant?"

"Not particularly if you just break magic into two phases. I simply substitute magic as a variable law that is capable of superseding any universal law depending upon the spell cast. You see take the Lumos as an example..." Riogel spoke as he fished out his wand from the inventory. 

He extended his wand in front of her and incanted, "Lumos~". A bright light appeared at the end of his wand.

"Lumos, a very basic spell and it creates light out of nothing. Shouldn't be possible but magic and bullshit so whatever. With just a spell, my wand acts like a lightbulb because I intend it to. This is like a magical law that supersedes the universal law that something like this shouldn't be possible. But if you ignore how the light came into existence, the rest of the laws remain the same..." Rigel placed the tip of his wand on the table and then used his left hand to block the light that left his wand.

"...See the light shadow that is formed on the table by my hand, and if you look at the edge of the shadow then you can see it doesn't have a defined edge. So not only does the light travel in a straight line, it even bends slightly around the objects as you can see from the diffraction pattern." Rigel explained.

"I'm sure you can conduct all the experiments we did with two sources of light and watch the light and dark rings form on a surface, but this simple experiment shows that not only is the light the same as any other source that we know and can scientifically create, but it also follows the same laws. That's why I think magic and electricity should be able to interact. If magic doesn't actually resist the fundamental laws of nature and energy." Rigel finished his rant and then whispered, "Nox~"

The light at the end of his wand fizzled out and so did Hermione came out of his trance, the look in her eyes told him that she wanted to do the experiments he talked him about so he quickly dissuaded her, "I'm sorry but I didn't notice the time, I do have to go for now, but hopefully we can meet again?" 

The brown-eyed girl nodded mutely as Rigel smiled at her, he waved his hand and said his farewell, "See ya later!"

Rigel picked up the book on Illusion magic because he already knew that the spell he needed was here, now he needed to do some experiments to see if it was viable or not.

'Who knew a hunting spell would help me save my hide if worse comes to worse...'

AN - Illusion magic would come back later in the fic.
