Field notes. Five months, four regions, and one door that wouldn't open. No sponsor. I paid for this out of copy fees and slept badly for most of it.

The question

This started as an attempt to price a knife.

A man in a Boundary Lands market was selling an iron paring knife, four inches, worn thin at the belly from decades of sharpening, and he wanted the equivalent of eleven years' Heartwood for it. I assumed he was chancing his arm at a stranger. I went back the following morning to tell him so and found he'd sold it, for the asking price, to a woman who had ridden two days.

So the price was right and I was the one who didn't understand the market, which is usually where the interesting work is.

I wanted to know where iron comes from and how much of it there is, and I have answers to both. I also wanted to know who ends up with it, and that's why this file exists.

Where it comes from

Nobody makes iron. I spent the first six weeks looking for a mine, and everyone I asked in those weeks knew there wasn't one and assumed I knew too.

Iron is recovered. It comes down.

The Chiming Snow is void-touched and things fall there. Nearly all of it is crystal, which chimes, and which is Ironvale's ordinary export, beautiful and worth very little. Perhaps once in a season something else comes down. It arrives hot and goes into the snow as deep as its size takes it, and it's heavier than it should be.

The people who go and get it are called pickers, which is the same word used for crystal gatherers and is deliberately unhelpful. Ironvale doesn't employ them in any formal sense. It licenses them for a share and otherwise stays out of it, which several pickers described to me as a good arrangement and two as the House keeping its hands clean.

I walked out with a picking party for nine days. I was allowed on the condition that I carried my own weight and did not write down where we went, and I've honoured both.

What the work is

Cold, and mostly walking.

A party is four to six, all mundane. That's necessity rather than preference, because a practitioner can't do the work (I'll come to why). The effect is that the entire recovery end of the iron trade is staffed by people with no connection at all, in a House whose whole identity is practice. Every picker I met knew this and about half of them found it funny.

They work by ground-feel and by watching where the snow settles wrong. Two of the six had been doing it more than twenty years and couldn't explain their method in terms I could write down, which by now I recognise as the signature of a real skill rather than an evasion.

In nine days we found nothing. I'm told that's normal and that the season's yield for the whole eastern picking ground was, that year, a little under two stone.

Two stone. For the eastern ground, for a year, worked by perhaps sixty people.

Why practitioners cannot do it

I'd assumed the exclusion was ceremonial. It's a hard fact.

A practitioner in contact with worked iron loses their connection for as long as the contact lasts. The connection is simply absent, and comes back when they let go. Every picker knew this. Several had watched it happen to a curious young Ironvale duellist, and they all told it the same way, with some glee.

Raw iron, the pickers say, is worse than worked iron and behaves less predictably. The one picker who had handled a fresh fall directly described it as like being switched off at the wrist and said she doesn't do it any more and lets the others lift.

Whether this is why iron kills practitioners, or a separate property that happens to travel with it, I couldn't establish, and the two smiths I put it to disagreed with each other flatly.

The smiths

There are, by the best count I could assemble, somewhere between nine and fourteen people in the dominion who can work iron.

The range is because three of them won't confirm it and one is probably retired. They are mundane, necessarily. They train apprentices who are also mundane, selected young, and the selection criterion I was given more than once was "a family with nothing in it," meaning no practitioners in living memory, on the grounds that an apprentice who awakens at fifteen has wasted six years of everyone's time and is heartbroken about it.

I sat with one for four days in exchange for splitting her firewood, which was the fee she named.

She is sixty-one. She has worked iron for thirty-eight years and has made, by her own count, one hundred and nine finished pieces in that time. She keeps a book of them. She showed me the book but wouldn't let me copy it, and I haven't reproduced any of it here.

"Everyone asks what it's like to work," she said. "It's like working iron. It's a metal. It goes hot and you hit it." She was correcting me. "The strange part isn't the metal. It's the customers."

The customers

Here is where the file stops being about a trade.

I asked her the obvious question, which is who buys. She gave me the obvious answer: mostly nobody, because mostly there is nothing to sell. Of her hundred and nine pieces, she said, well over half were commissioned repairs and re-workings of iron that already existed. Somebody's grandmother's knife, re-tanged. A ring resized. Actual new material comes to her perhaps twice in three years.

I asked what the new material becomes.

"Knives, mostly."

I asked how many of the knives.

She thought about it for a while and then said that was a good question and she would rather I asked somebody else.

The arithmetic

I did the sum on the road afterwards and again since, with better figures.

The eastern picking ground yields a little under two stone a year. There are three grounds. Nobody would give me a total but the pickers' own estimate for the whole Chiming Snow was six to eight stone annually, and the two Ironvale licensing clerks I spoke to didn't contradict this when I put it to them, though that isn't the same as confirming it.

Against that: the licensing register. Ironvale keeps one, it is a public document at the frontier posts, and any citizen may look at it, which I did, in three separate posts, over two months.

The register records recovery, transfer and destination. It is well kept. The clerks are proud of it and one of them walked me through the older volumes with real enthusiasm.

The recovery figures and the transfer figures agree with each other and with what the pickers told me.

The destination column is where it stops working. Roughly a third of transferred weight, across every volume I examined, goes to entries recorded as institutional acquisition, with a reference number and no named recipient.

I asked. I was told that institutional acquisitions are Crown-side, and that the frontier posts hold the reference numbers but not the names. The clerk said it in the tone of a man who has explained a genuinely dull administrative fact many times and has never once been asked a follow-up question.

I asked who holds the names.

He said the Registry does, and that I was welcome to write to them, and gave me the correct form of address. He was helpful throughout and had no idea he was telling me anything.

The door

I wrote to the Registry. Twice.

The first reply came in eleven days and was courteous. It explained that acquisition records are administrative rather than public, that the licensing register is the public instrument, and that my enquiry had been noted. The second reply came in six days, was shorter, and said the same thing without the explanation.

Nothing improper has been demonstrated. The Registry licenses practitioners and iron is a strategic material, so a Crown interest in it is legitimate, and it would be negligent to lack one. A third of a very small quantity is still a very small quantity, and a third of six stone a year is nowhere near an army.

What I have is an unaccounted destination, a helpful clerk, two polite letters, and a smith who declined to tell me how many knives.

So far that's a hole where a story would be if there were one.

What I actually learned

Here's what the five months were worth.

The iron trade is the only part of the dominion's economy that runs entirely on mundane people, from recovery to forge, by physical necessity. In a world organised around practitioners, the one material that matters most strategically can only be touched by those who are not. Nobody I met remarked on it.

The quantities are far smaller than the reputation. I came in assuming iron was rare in the way that good sapphires are rare. It's rare in the way that a specific dead language is rare. Most people who fear iron have never seen any.

And the superstitions are wrong in an interesting direction. Both the common beliefs, that iron wards the Deepening and that it curses those who hoard it, are unverified, and I found nothing to support either. But every picker and both smiths independently described the same phenomenon, which is that iron switches a practitioner off at the point of contact, and all of them treated it as a workplace hazard, on the level of a hot bar or a bad ladder.

The most remarkable property of the most feared material in the Heartlands is common knowledge among fourteen smiths and two hundred pickers, and I've never seen it in a treatise.

Costs: five months, and I'm poorer than when I started. I'd do it again.

The two Ironvale licensing clerks and the pickers of the eastern ground were more helpful to me than any House has ever been, and none of them asked what I wanted it for.
