[She let me lie-detect her and told me she wants to help me take over the world, and told me what's wrong with stars. I don't think she'd do you harm. Although you might not like it here if you're claustrophobic or scared of heights.]
[I think I actually agree with her that it's not the sort of thing that you want generally known, so don't go spreading this hither and thither, but you've got a shot of finding out if you hang around me enough anyway. Coins are mean and will try to bite; stars are the ones with enough oomph to reliably screw you up. I think that might be the spare magic you saw escaping. A hex'll wish a star toothless, so to speak.]
[I agree with her that it's not the sort of thing you want generally known,] says Lazarus. [Stars are scary.]
[Lemme ask Libby to have you come look at this pretty globe,] Bella wheedles. [Bring a coat.]
[...okay,] he says, [if only to resolve the bizarre mental images I'm getting of where this thing might be.]
"Can Lazarus come have a look?" Bella asks. "If not I think I'd just as soon make my own from scratch rather than trying to improve on this one."
"Sure he can," says Libby. "I assume it was you who just told him about sevens?"
"He asked, and he'd find out anyway once I started flinging them around. You have some who-knows-about-stars monitoring system up, I take it?"
"Yep," says Libby. "Curiously, there's always been one person who didn't fit in any of the categories 'knows', 'suspects', or 'doesn't know'. Less curiously, that person is you."
"My ingot power probably won't let you check, assuming it looks for the contents of my brain and not for whether anyone has ever told me or something," says Bella. "Is Lazarus on your allowed-to-leave list? I imagine he'd be alarmed if I ported him here and he was boxed in."
"The list controls who can move people out of here, not who can be moved. Bring all the friends you like."
"I believe you've met," she says, bouncing on the balls of her feet.
"Oh, it's not that cold," he says, glancing around. "The enforced vacuum two feet away is a little unnerving, though."
"Canadian," snorts Bella. "I'm only not curled up and shivering 'cause temperatures no longer harm my magical magical self. Tell me about this here globe."
"It's very pretty," he says. "It finds mints. Someone put a lot of thought into it; it's elegantly designed. But it can't see through your wards, because they're about on the same level."
"So it could see me again if it was just juiced up some," Bella says. "Okay. I suppose I'll just add layers for ingots and stashes of coins. We've got mints being pins, so let's make uncontrolled stashes treasure-map style Xes, and controlled stashes O's so it's all tic-tac-toe-ish, and ingots can be flags in whatever color coding the magic naively considers appropriate. If you don't mind me doing that to your pretty globe, Libby. Lazarus, any ideas on making extra sure the search is comprehensive? Ideally with cleverness and not just oomph, since as I recall the coin-based oomph does not exist to overpower an ingot with a relevant contrary opinion."
"You could probably make the flag look to me the way the ingot's power would actually look," he volunteers. "So we could tell ahead of time what these ingots' powers are like. And have it look separately for powers and for people with powers, and then combine the results when they agree, in case someone managed to hide themselves but not their power or vice versa."
"Have it display any magic that's hiding something as an exclamation mark on a stick," Libby suggests, "and anything that doesn't make sense, such as someone who isn't magical but isn't not magical either, as a question mark likewise."
"I like it. And maybe little gems where there's coin-operated artifacts, like my motorcycle or this globe. And little boxes where there's anything disobeying the laws of physics but 'none of the above'. Sound like a plan?"
The hex goes. The globe lights up like an ornamented Christmas tree.
"And one for oomph."
Oomph.
