Zara

Three young traders come to her post most days — Bo, Juno, and Vero — and each of them brings her the same worried question in a different shape. Is this a good trade or not? And every time, Zara sets down whatever she's holding and walks them through the very same three-part weighing.

"First," she says, holding up one claw, "does it help you? Not 'is it nice' — does it get you closer to the thing you're actually building? Second," — a second claw — "is it fair to both? A trade that only fills your basket and leaves the other trader worse off isn't a deal, it's a grab, and grabs come back around. Third," — a third claw — "did you ask it kindly? You can drive a hard bargain and still be good to the person across the table." She lowers her paw. "Help you. Fair to both. Asked kindly. Weigh every offer those three ways before you say yes."

But the thing Zara teaches first, before any of that, is the quiet secret that keeps her so calm: know your cove. Before you ever walk up to trade, decide what you'll do if there's no deal at all — dig your own clay at the far cove, wait a round, trade with someone else. That back-up is your floor. "Once you know you'll be all right either way," she tells them, "the fear goes out of you. You stop grabbing at bad offers out of worry. You can look any trade in the eye and simply ask — is this better than my cove, or worse?"

The three of them roll their eyes sometimes, because she says it so often. But Zara has watched what happens when they forget. Bo, keen to build, takes a lopsided deal because he's short of wood and panics. Juno, who barely needs anything, wanders into a trade that helps her not at all. Vero, always out in front, hands a good straight to the trader already winning, and can't understand why the gap keeps closing. Each of them learned the hard way what Zara had told them the easy way.

"I'm not here to win for you," she said to Vero once, ears tipping forward, warm and plain. "I'm here so nobody can win off you. Weigh the offer three ways. Know your cove. And when a trade fails all three — walk, with no drama at all. Half the time, walking is what brings the fair offer back to you."

Vero grumbled, but he felt the steadiness settle into him — the calm that comes from knowing you'll be all right either way, and from having a fair, plain way to weigh any deal the world puts in front of you.
