"Water can also be a problem. What we have is only modestly sanitary and could be cut off. It doesn't sound like you'd be too willing to make us weapons, but what about shields? So that they can't blow us up, or send tracker-jackers into town at night, or whatever."
She doesn't snap her fingers this time; she makes a circle in the air with her hands and then brings them away sharply. A small pearly figurine appears: a unicorn, one hoof raised, bending its head so the blunt point of its horn is on a level with the other three.
"If you put it in water, or even something that's mostly water, it purifies it and then makes more."
"Why is it a unicorn?" asks Isabella quizzically. "I mean, does it have to be, or could you make it a little sphere or a cup or something?"
"It is," agrees Bell, wiping tears off her face. "So shields would look like... shields? Or more like our protection amulets?"
Bell snatches it out of the air as though afraid it'll fall, and then bites into it. "It's good," she says, more happily than she was a moment ago.
"So if Isabella asked it for belladonna it wouldn't work," Bell says.
"But it's not for spell components, it's for food. And it does food. Thank you," says Bell sincerely.
"I think I'm composed enough to go set up a Belltower, now," Bell says to Isabella. "Let's go get some keys. And see what furniture we have to start out. Tony, do we get a furniture budget too, in exchange for whatever Isabella wound up doing for your cooling system?"
"Sure," he says. "I mean, don't start installing diamond chandeliers, but I'll cover some furniture and general prettying-up."
"If we want a shiny chandelier we'll buy a bucket of ice and have Isabella cast at it," says Bell, smirking slightly.
They each collect a key to "a room of suitable size" and the room number from Bar, and head for the stairs.
