#On the Custody Number
A ghost tag is a salvage custody strip carrying a number the Bureau of Relics once issued, in good faith, to an object it can no longer find on paper. The number is real and so is its history. The fragment now tied to it, warm in its wrap and gritty with lime, has borrowed that history the way a deserter borrows a dead man's greatcoat. It fits badly, and nobody at the depot will say so.
The honest strip belongs to the licensed Reliquary Salvager. It is a wax-sealed paper band with a sequential number matching a line in the Bureau's salvage register. On its face the Salvager writes five things: item description, site coordinates, resonance reading, condition, and his own licence number. That makes five small oaths. The register holds the other half of each one, and custody is what you get when the two halves agree.
A ghost tag supplies one half and swears the other half burned.
Do not suppose that the fragment is false because its paper is false. It is often the most honest thing in the transaction. The bone is bone, and the saint-glass hums as saint-glass hums. Only the biography is forged. In the trench courts the clerks use the same phrase for a tag with no body attached. That is a different filth, kept in a different drawer, and it can teach us nothing here.
#On the Dead Registry
The Shadow Pullers do not make numbers up. A made-up number lands on an empty line, or on some other parish's chalice, and the first clerk with a lamp and a grudge catches it. They hunt for registries the Synod has lost. Their own dossier lists the causes with a craftsman's fondness: fire, flood, shelling, damp, rats, seizure by the Bureau of Purity, and convenient misfiling. Each disaster leaves behind a range of numbers that have a past and no present. Every one of them once described a real object, and every one is now an orphan of ash or mould. You can challenge a number from such a range only by producing the page that killed it, and that page is gone.
That is the whole of the commerce.
The salvage economy that feeds these ranges was not always collared. The First Quake-Ledger of A.S. 105 exposed an untaxed trade in recovered holy matter and drove the Bureaus toward a broad licensing framework. The Singing Plate Disaster of A.S. 131, near Bastion-Przemyśl, made on-site quieting compulsory and four-tier triage binding. Every reform added paper, and paper burns. The Ledger does not say when the first ghost tag was cut or whose hand cut it. I will not decorate that silence with an inventor.
#On the Credible Strip
A crude ghost tag dies at the first counter. The good ones are made by people who have studied clerks more closely than clerks have ever studied themselves. They match the wax tone of the province and the decade, the slope of a hand at the end of a long shift, and the abbreviations a receiving office used before some reformer in Strasbourg tidied them away.
Then they ruin the strip, correctly. It gets a damp fold, an old smear, a grey thumbprint of tallow, and a hesitation in one numeral where a clerk might have stopped to scratch his neck. A crease crosses the witness line, as if the strip had spent years folded in a satchel and not one night on a bench under a candle. The specimen described in the Shadow Puller dossier had a smear at the right corner, a pause in the third digit and a fold across the witness line. Other specimens choose other wounds. There is no single recipe, and I will not print one for the education of apprentices.
The Seal-Forger knows the governing law: perfection confesses. A strip too clean for its claimed age announces itself before anyone breaks the wax. Amateurs fail here most often, because they mistake a forgery for a fair copy.
Bureau of Relics inspection guidance holds that ghost tags "betray themselves by crudeness of hand and seal."
The guidance describes the ghost tags its inspectors catch. I have recorded, and I maintain, that in at least nine audited cases the ghost tag was more internally consistent than the provincial record it imitated. Crudeness identifies the failures. The successes are never brought to inspection.
#On Its Passage
The fragment comes out first, from a Brest wet vault or an Irongate quake seam. It is wrapped in cloth lifted from a shrine laundry, and the strip goes on while the wax tack is still soft on the gloves. After that the strip and the fragment travel separately from the truth.
The strip goes with the story seller, the crew's most despised and best-paid rank. A strip with no story is just paper. A story with no strip is gossip. Put together, they become provenance. So the story has to fit the number: which chapel, which flood, which night the wall gave way, and why no living witness signed. The seller takes this package to shrine-brokers, patrol officers, chaplains short of a relic before inspection, and the Relics intermediaries whose innocence has a purse attached. From there the fragment goes through one of two doors. One is the shrine trade. The other is a quiet sale back to Relics through a cut-out, by which the Bureau buys back its own property and does not ask which sewer delivered it.
Further on, the incentives get softer. Some Relic Authenticators will smooth over a documentary gap. Shrine custodians and Saint-Bone Melters like provenance with holes in it, because the price lives in the holes. I do not claim that every authenticator launders stories. I claim that the trade has never lacked laundresses.
The direct obstacle stands at the hole. A Contract Sanctifier binds custody before anything moves. He may suspend unsafe extraction, and he may invalidate any tag that has been tampered with, reheated, washed, scraped, or improved by a man whose penmanship exceeds his clearance. He also holds the fee, which does not mature before custody does. Show a ghost tag to an honest Sanctifier on site and you have handed him a signed confession. So the Pullers avoid the hole. They show the strip at a desk weeks later, miles away, to a clerk with no Sanctifier at his elbow. Some Sanctifiers, it should be said, sell discretion and convenient classifications, and the Bureau knows which ones.
#On the Parallel Ledger
Detection starts with the hands and ends with the rubble. Salvage inspectors compare the number, the wrap, the condition of the seal, and the recovery story against the ruin it claims to come from. They want to know whether that ceiling could have fallen that way, whether that vault ever flooded, and whether the lime on the cloth matches the lime in the crack. Authenticators look for missing witnesses, mismatched seals, and the same lost-record excuse turning up too often. One flood is misfortune. A province full of floods is a workshop.
The Shadow Puller code forbids selling the same ghost tag twice within one province. The rule shows they know the number is their weak joint. It does not make a second province safe. The Bureaus write to each other slowly, and slowness has never been mistaken for blindness by anyone who has been hanged.
Purity is the greater hazard. It keeps its own books of what it seized, inspected, quarantined and condemned. A register burned in a Records annex may survive as a single line in Purity's inventory, giving object, condition, date of seizure and the name of the officer who signed. A forger who chose that number has chosen a page he cannot see. Discovery has no fixed sentence. A crew caught with a failed ghost tag may lose fee, licence, fingers, name or breath, depending on the object, the investigator's mood, and how useful the fragment has already proved to Relics.
No tag, true or false, quiets anything. Field triage sorts matter as safe, singing, unclean or do-not-move. The bench grades it Ward-safe, Votive, Contaminant or Fraud. Custody is a third record and answers to neither. A perfect strip can travel on a Contaminant, and a forged strip can travel on a sound Votive bone. The A.S. 131 chapel delirium happened under a temporary custody slip. Nothing in that record says the slip was forged, and nothing in it suggests paper helped. Only a Litany-Engineer quiets a singing fragment.
#On the Brest Intercept
PURCHASE INTERCEPT — BASTION-BREST, A.S. 176 Item: saint-housing fragment associated with sustained C-sharp incident. Seller: "no one." Buyer: Relics sub-clerk acting without written authority. Ghost tag range matched registry lost in chapel flood, A.S. 143. Fragment accepted, re-sealed, classified. Seller later found ███████████████ with wax under nails and no tongue.
Here is the procedure in full, recorded by the Bureau that was robbed. A Brest registry drowns in A.S. 143. Thirty-three years later a number range from that drowned book comes back to a desk, tied to a fragment still associated with the C-sharp. A sub-clerk with no written authority pays for it. Relics accepts the fragment, re-seals it and classifies it. The object is then the Bureau's, on the Bureau's paper, and the forged strip has done everything it was made to do.
The same year, Brest's incident file records that Crew 14-R scraped a saint-housing inscription and produced eleven minutes of sustained C-sharp. The intercept does not name the seller's crew. The Codex will not join the two records for the reader's convenience. As for the seller's condition, the record gives the wax and the tongue and blacks out the rest. I have no explanation to offer and decline to borrow one.
#On Present Custody
By A.S. 201 ghost tags turn up wherever the Sagittal Line cracks. They come from the underworks of Przemyśl, the wet vaults of Brest, the quake seams of Irongate, and the chapel foundations of Sibiu. The Licensed Recoverers condemn them in public and study confiscated specimens in private, to train their eyes against the next batch. Their best anti-forgery manual has a forger for its anonymous co-author.
The Bureau of Relics depends on recovery it can deny, and ghost tags are the paper that makes the denial possible. It burns the forger and keeps the fragment. Then it files the fragment under a number it once issued itself, which by long practice is the safest place to hide anything from the Synod.
