I have a transaction I'd need it for in an hour; if the note is quicker then form is less important."
Who has been held for him. Turns out the outfit will take his writ and give him change in a similar format, if he likes.
Huh. Could have saved lugging the bag for twenty minutes. If that's typical, though, probably better to pay with coins so as to less visibly scream "I'm carrying several human beings' worth of cash" to anyone who looks.
"Do I just hand these to you, or is there something more official so nobody thinks you stole them?"
"So, do you have as little idea what the immediate future looks like as I do?"

"I would be glad to have your help if you're offering. I know approximately what the medium term plan looks like, but am completely lacking in information on questions like what kingdom to do it in and what sort of food people eat here and everything in between."
"A thousand. So you'd know better than I how much I can afford to pay you; my only reference points are curiosities and slaves."

"You don't have any more things from the magic to sell, do you? If that's your entire fund it's worth making sure that whatever you do first can pay for itself."
The obvious first thing to make is gunpowder. Requires very few starting resources, and useful for demonstrations if not much else. Would also be indescribably valuable for militaries, though I hesitate to hand control of the world to any country I just met."
