"Hmm... I could give you something like I have, a wish that keeps your coins tucked away where only you can get at them," she says. "It's very convenient. Although while we're at it I think I might upgrade mine, now that I know there are potentially more kinds; it's handling the eights a little inelegantly. If you give me a couple of sixes and a little time to think, I'm sure I can come up with something better."
She takes a few seconds to ponder, and then two of the coins disappear.
"There. When you make coins they'll automatically go into storage, you can consult storage at any time to tell how many of what kinds in what colours are in there - there's not much practical purpose to knowing the colours, but there wasn't a good reason not to, either - and take coins either 'halfway' out, so they're only substantial enough to you for you to wish on them and aren't apparent to anyone else at all, or all the way out so you can hand them to someone else. Lazarus, would you like one too?"
"That is much more elegant than what you previously had," he says. "If I'm being drafted as a dragon completion assistant, then - yes, I suppose, all right."
"Dragon completion assistant might be more fun to say," he says contemplatively. "And less self-aggrandizing."
"At some convenient moment I can take us back to Lazarus's place," Libby mentions. "Or anywhere else, for that matter, but I'm not getting much of a tourist vibe from you."
"There's no particular reason not to show you our moon while you're here," she says. "If you're interested, and feel like sparing a six to take care of the atmosphere problem. I'm not sure what your situation is exactly, but around here, we need to breathe air and the moon doesn't have any."
"Air collects around planets and places much smaller than planets aren't big enough to collect any. If you want a more complete and rigorous answer, I have an astrophysicist on call."
"Not at all. The slight amount of trouble it could potentially be would be covered if you gave me a six so I could arrange for the no air thing not to be a problem."
She contemplates the six for a few seconds, then wishes on it. "There. We will be covered if I teleport us to the moon. Shall I?"
