Verdigris Lung

A vault physician's plain clinical warning on Verdigris Lung, the wasting sickness of salvors who work sealed, unaired places too long.

I have been treating vault crews for eleven years, and I no longer soften this for anyone, because softening it is what kept my worst patients working past the point they should have stopped. If you crew for a salvage outfit, or you love someone who does, read the whole of this and not just the part that reassures you. Old bronze left standing in a shut, damp place for four centuries grows a green skin — verdigris. In a vault that has been flooded and sealed that long, it is not a stain on one fitting; it is a fine bitter dust suspended in every breath of standing air the moment the seal breaks. You cannot see it settling in you. You will not feel it happening. You will only, eventually, notice what it has already done. The first sign is a cough, and it has a particular taste — most patients describe it as tasting of coin, which is an ugly joke the trade makes about itself and also, medically, an accurate description. This cough is not dramatic. It does not stop crews from working, which is precisely the danger: it is easy to work through, and working through it is exactly what makes it worse. The second stage is in the hands. A salvor notices it first trying to pick a lock or count coin at the end of a shift — a fine tremor, gone by morning, back again the next evening in the vault. This is the stage where the sickness can still be slowed, and almost never is, because a shaking hand still counts as a working hand, and a working hand still gets paid. The third stage is the one nobody in this trade wants named plainly, so I will name it plainly: the mind goes soft. Names slip. The day of the week goes first, then the season, then, in the worst cases I have treated, the face across the fire goes unrecognized. This does not happen overnight. It happens over years of exactly the choices described above, repeated, by people who told themselves each individual shift was fine. Understand what causes this, because the trade gets it wrong on purpose: it is not the relic you carry home. A working sitting dry in your pack, in open air, does nothing to you. It is the shut, wet, unaired room itself — the hours spent breathing what that room has been holding for four hundred years. A salvor who cracks a vent, waits out the bad air, and comes up often takes a fraction of what a salvor who seals themselves into a flooded gallery for a week takes, working the same vault, on the same haul. I have treated both kinds of salvor from the same crew, and only one of them still knows my name. What helps: air, and stopping. Not a slower pace — stopping, or at minimum cracking a vent and waiting before you go back in, every time, without exception, even when the light is failing and the crew wants to push through to the good room before nightfall. There is no third option I can offer you here. What does not help, because I am asked constantly and I am done being polite about it: holding your breath does not help. A wet cloth over the mouth does not help meaningfully past the first hour. Drink does not help — it slows the cough you'd otherwise notice, which only means you stop noticing the warning before it's too late to matter. No charm sold at any market stall in this town has ever changed a single case I have treated, and I have asked every patient who wore one. I had a patient, three years back, who could still name every fitting in a working laid out on a table in front of him after he could no longer reliably name his own daughter. I am not telling you that to frighten you into buying a tonic from me. I do not sell one. I am telling you because you asked me to be honest instead of comfortable, and because the ground within an easy walk of any gate in the Vale has been worked out for two generations now — which means the good Old Work left standing lies deeper, wetter, and longer-shut than it used to, in exactly the vaults this sickness comes from, and every year the trade sends more people further into precisely that kind of place. Come up often. Stop before your hands do. I would rather see you in my office complaining that you quit too early than not see you at all.
