"I suppose wizards might have an easier time counterfeiting but then I'd also expect you to have an easy time conjuring up all the gold you found convenient to have, naively I'd expect IOUs to hold up better because you can go ask somebody 'this says you owed so-and-so this amount for this thing, is that true'..."

"Goblins are really strict on counterfeiting, and there're spells to check, and it's a small enough community you couldn't get away with it for very long..."

"What're goblins like?"

"Uh, short, wrinkly, greyish skin, long pointy ears, long history of wars with wizards which even having only read our side of the story were probably mostly our fault, run Britain's major wizarding bank..."

"That sounds... tense."

"A bit. I wouldn't have files and files on how to run the world if it was running itself well enough."

"Suppose not." Pause. "To answer your earlier question, no I have not done anything except reembody Elves for several months before finding this place."

"Well.

Want to help me revise plans for running the world in light of lots and lots of evidence on what works apparently already existing? It sounds like more fun than months and months of reembodying Elves and I take it it doesn't even slow the return of the Elves to life. 

- what happened -"

"There was a war."

Pause.

"I suppose it would be inappropriate to take you up on your invitation to go modernize your world without telling you that they died because I destroyed their planet."

"Why?"

"The war was against an evil god - who could make binding oaths, that I could verify - who really really wanted it destroyed - and. Needed to stop doing what he was doing."

"And you can bring them back."

"I can bring the Elves back."

"There were other peoples -"

"You wanted to know what kills a god."

"I hope it was worth it."

"Was or I wouldn't've done it."

Nod. "None of this affects how good it would be to have future hospitals and so on, so if you want to come give us future stuff you can still do that. Though we should make really sure you're either protected against magic mind control or just nowhere near any wizards at any time."

"You're a wizard."

"And apparently could make you destroy the world, objectively you shouldn't trust me that much."

"If you point your stick at me unexpectedly we might have a problem."

"Fair.

So, did the evil god keep his end of the deal?"

"Yes."

"I would like more information but it doesn't need to be now or in the format of a conversation."

"I have the oath we got out of him written out if you want to see. It's very thorough and refers to a lot of evil things you'd probably need more context on the brain backups to get."
