"Er, yeah, I really don't think you should have an example. I mean, I'm not sure we can ever do that safely, I don't know enough physics for that—wait, actually, there are nuclear energy plants that might be useful, they use the same principle but instead of going boom they harness the energy to get electricity."

"I can spellsense things at a little bit of a distance, if that helps - maybe thirty or forty feet if I know exactly where to aim, but it goes through walls and things no problem - it's a different thing than the magic vision I was talking about earlier. ...actually, the magic vision might be exactly what we want for this; there aren't many situations where I'd want something to teleport as soon as there was magic nearby, but this is one. Would that work, do you think? Enspell the bombs to be able to see magic and teleport if they ever do?"

"I mean, it's probably a thing that's possible if you say it it, but how would it help?"

"It'd just be a safety measure for while you were telling them about the wixen, but it should be a pretty good one - they won't be able to attack any magical people or places, is the idea, and if they don't try, they don't even know that the spell is there, so it doesn't upset them. And there's... not much chance, anyway, I suppose there could be magical people around the bombs for reasons we don't know about, I can add a timer to the trigger just in case... of the spell getting activated when we wouldn't want it to be. It'd be better to get rid of the bombs entirely, but if they can just make more, that's not really an option."

"Well, nuclear weapons aren't the only thing they can bring to bear upon us. Machine guns, napalm, more mundane kinds of bombs. If it came down to it, Muggle culture would be enough because they view powerful artifacts as knowledge that can be distributed freely around. Also there are way more of them than of us. But I don't think they'd want to destroy us, at any rate. Well, some would, like religious nuts who would say we were devil worshippers..."

She blinks. "I'm not sure why you'd want to stop magic being a secret at all, then - it's one thing if someone needs a bit of a shock to get them to stop and think, and something else again if there are going to be problems even if they do. Or did I misunderstand something?"

"Well the main reason is that our magic is really good at, say, multiplying food or creating water, and it's actually possible to become immortal with it though only one person ever did it and they decided to go ahead and die anyway for some reason. We're also basically immune to regular non-magical disease and strife, and even without magical immortality elixir live far longer than Muggles do. So, uh, basically I just want to help everyone and uplift the species and eradicate disease and death and poverty and suffering."

The kobold takes a few seconds to consider this. "I think you're trying to do too many things at once."

"Hmm, maybe, though I'm not actually doing all of them. My current project is the networking-and-getting-influence one so that muggleborns will be treated more like humans, and then that can be expanded to nonhuman sapients. But there's precedent for both a thing that creates an elixir of immortality and a substance that cures all diseases, and the branch of magic that's used for that is uncommonly learnt and has certain other characteristics that make me confident I will be able to replicate those things when I know more."
