"There were wars against and using magic in the past, in other places. A member of the Council said his entire race was nearly destroyed by it, and our mentor had witnessed enough of it to be fearful of what it could do." And Jayce is understanding, to a point. Those are logical reasons to fear something, but not logical reasons to refuse to ever revisit the idea again. "But progress requires pushing against what you fear." That's true of him. He may be more cautious now than ever before, but he still thinks Hextech was the right thing. He can't regret it just because it was misused (by him).

"No, they wanted it for themselves, once they saw the benefit. And they can't exactly punish the creators of what they coveted." They could, sure, but it wasn't a smart idea. So instead it was spun around, that these prize students of Heimerdinger made something incredible, and the Council could give them the funding and space and power to use it. "The benefit of it was obvious once it was proven and not a theory. Everyone agreed on that." It was stretching the mind to the possibility that was the hard part.

"They wouldn't be able to. I had gathered all known crystals at that point, and you can't work any of it without them. Which I'm guessing is true here of the New Magic, it's a natural safeguard." Jayce will have to learn more by going to the academy, but it makes sense to him. If he wants to replicate Hextech or learn what New Magic is, it'd have to be through academia and that route. Honestly, that may be one of the things Heimerdinger was correct about. Safeguards over something that powerful are necessary. "I'm sure it's the type of thing they've already thought through here, since they're ahead of us that way."
