"But then why I am not indestructible becomes an interesting question."

"Spell has side effects you don't want to put up with unless it passes all your tests?"

"...sure, okay, I think I can sell that if we can find a volunteer who doesn't mind cutting off the wings and being Imperiused."

"I'll write to the Poppy Garden staff."

"Thanks."

"...if daeva can be Killing Cursed is there a good way to cover more than the one test subject?"

"I could probably figure out a way that doesn't require involvement of and significant concealment from actual murderers, not right away but I take it they're not really in a hurry..."

"They are not."

"Do they - usually have reasons for wanting to die that could be changed -"

"I haven't made a particular study of it but maybe some of them."

"Because we should probably see first if regular access to cheering charms and company does anything, I don't know what sorts of things make daeva want to die but wizards mostly want to die for transient reasons or illness ones -"

"Charms maybe but I doubt access to company per se is it? Hell has people. I suppose some of them might just be socially impaired enough not to get value from that."

"Well. We can try first, it's not like we're pressured for time."

Nod. "I'll mention in the letter that there might be non-death means of helping the folks in the gardens presented by wizarding magic."

"What've you been up to-"

"Elf-chipping basement dwellers - they spontaneously die, can't get them to not do that - and taking brain scans of magic people, which if they can be trusted suggest that Michael is not going to have problems with his experimental brain surgery."

"Oh, good. We have pretty much Muggle brains?"

"Looks like, or you're persistently fooling a variety of scanners into thinking so."

"I would not expect magic to do much fooling of Muggle scanners. Interfering with, maybe, but I assume that'd look different."

"Some of them did actually glitch some but when they worked they were consistent."

"It's going to be inconvenient if magic consistently glitches tech. Maybe my father'll find a solution."

"My next experiment was going to be wrapping electronics in live plants, see if being contained in something organic is protective. Wouldn't help with the chips naively because all they do is talk to stuff that is not likewise inside the body, but if you could put a computer in wood..."

"Ooooh, that'd be super convenient."

"You would have to water your computer. But otherwise yes."

"I would have to ask my elves to water my computer," he corrects him. "I am a wealthy slaveholding citizen of 1802."
