Old Work
also called temple-bronze, the old bronze

The trade word for salvage out of the dead empire's works — bronze cast and alloyed in ways no living smith can match. Raw scrap sells by weight; an intact working is worth a season's wage; the rarest pieces are named things nobody can price. It is the one trade that lets the frontier eat.
Ask anyone in the Vale where the coin comes from and the answer, one way or another, is Old Work. The Vallen Imperium left its bronze in the ground everywhere it built — in flooded vaults, sunk temples, the ribs of machines whose purpose died with the men who ran them — and that bronze is simply better than anything made since. The alloy holds an edge a modern smith can't put on new metal; the castings are seamless where a living foundry would show a join; a temple-bronze fitting four centuries in the wet comes up green but sound. Nobody now knows how it was done. The priest-engineers who knew are dead, their books are ash or locked in Aelvyrenn, and every smith who's tried to reproduce it has produced something worse. So the trade doesn't make Old Work. It digs it up.
There are three grades, and every salvor knows them. Raw scrap — broken fittings, cut lengths, melt-stock — sells by weight to any bronze-buyer, and it is the bread-and-butter of the whole frontier: a bad haul of scrap still buys the winter's grain. A working — an intact device, a mechanism, a fitting that still does the thing it was made to do — is worth a season's honest wage and is what a salvor prays to find, because a working is a tool the living can't build, and tools that open places are the whole of an explorer's power. And then, rarely, at the bottom of the worst places, there are the named things: single pieces so far beyond the rest that they have their own histories and their own names, that no two are alike, that can't be farmed or forged or found on demand — only earned by going where no sensible person goes. A named working is not priced. It is fought over.
Old Work is not the whole of what the Vale trades — the belt sells what it grows, and a found device from higher and stranger workshops is its own market — but it is the pillar the frontier economy leans on, and it leans hard. It is also finite (see the-thinning) and it is not free of cost to dig (see the-long-ring). The grim arithmetic under the trade is this: the empire that made the good bronze is dead, the living can only strip its corpse, and every year there is a little less of it and it lies a little deeper.
