774 Arcane Magic
Eiro stretched slightly. Being this far away from the manor right now wasn't particularly great for his body. His body was at about 70% of the integrity it should be at right now. Which was pretty good when you considered that usually by now this body would be a puddle on the ground, but it was to the point where it was pretty damn uncomfortable to deal with. Then again, the pain from his body falling apart over the couple of days before Eiro entered his coccoon was incomparably worse.
Currently, the demon was at the academy. For the past few weeks, he has had a replacement filling in for him and relaying the tasks and homework that he wanted to give to each of his students. It did mean that the students that he was particularly paying attention to were a bit left behind, since Eiro couldn't tell his replacement teacher about every single thing he was taking care of, but even so, they were still supported alongside all the other students in Eiro's classes, so at least they didn't completely lose out.
He stepped into the lecture hall, and the students immediately perked up seeing that it was Eiro instead of the substitute that has been teaching them for the past little while.
"Lord Daemonherz!"
"You're back, where have you been?"
"Are you alright? I heard you were sick!"
The room was silent for a few moments, the only sound coming from the scribbling of pens that were still trying to finish their notes. But then, a student raised their hand, and Eiro nodded at them.
"Is it... 'Arrow Volley'?" they asked, and Eiro quickly nodded his head.
"Correct, that is indeed the spell that I was thinking of. The 'Arrow Volley' spell is one of the overlapping elemental spells, as many of these standard, basic spells are these days. The element can be swapped out in many of them, and the spell can otherwise function without any other major changes. However, there is one difference in the Arrow Volley spell. Other projectile spells require an angle and force input that needs to be calculated, and while the Arrow Volley spell does that too, it is a bit different. It practically shoots a 'guiding' bolt first, and then the location where that bolt hits is registered as a location that all other arrows are aimed at. Basically, you have the target body, which would be the element, and the starting location, as well as the destination," Eiro explained, noting down the similarities between the spells.
Of course, the 'blink' spell was many, many times more complex, but it was true that a very important centrla part took some inspiration from spells similar to the 'Arrow Volley' spell. A main difference was just that there was no guiding bolt that was shot out, and the destination coordinates had to be set manually during the construction of the spell. The students still followed along curiously as Eiro continued to explain the intricacies of this spell. And of course, there was a question that came up surprisingly late.
"How do we cast Arcane spells?" one of them asked. Of course, arcane magic was a concept that didn't have a lot of research behind it. There weren't that many people that even knew the principles behind it, let alone that were actually capable of using it. Since Merlin was a professor at this academy in the past, this place actually had some of the best information about it so far, but even so, it looked like Merlin never taught much about it.
"Arcane magic is a special sort. It's practically 'non elemental' magic, using a transformed, 'pure' mana. Basically... imagine taking the purest mana you can imagine, and infusing it with the element of 'Magic'. It's hard to control, since you need to draw your own essence away from it to create arcane magic in the first place, and you need to have an extremely high understanding of magic to even make use of it in a way that is worth it. But once you get to that point, arcane magic can do many, many things that other magic can't. And well, I think it's about time that I pass that magic on to you all," Eiro said with a smile on his face, "From now on, I will be instructing you all on arcane magic."
