#On the Host That Walks Until It Opens
The Wormhost is a man used as a sealed reliquary by the Lie, except the relic inside him is alive, hungry, coiled, and waiting for the command to make of his ribs a door. The phrase has misled more officers than enemy camouflage. “Host” sounds almost medical, almost hospitable, almost temporary. It is tenancy by parasite, occupation of flesh, annexation of the person under a vermiform seal.
The first cruelty is that the victim remains recognisable. A Wormhost walks with the column, breathes in formation, eats enough to keep the outer machinery credible, answers simple questions, carries a rifle badly or a bundle well, and may even make the sign of the Cross if the parasite has learned which nerves govern the hand. A farmer remains a farmer until his chest becomes a hatch. A refugee remains a refugee until the gate closes behind him. A surrendering soldier remains, in every outward category available to a tired checkpoint clerk, a man.
Inside, the thing coils. Engineering calls it parasitic. Medicine calls it invasive. Doctrine calls it an abomination permitted by sin. The trenches call it the reason no one embraces prisoners anymore.
#On Seeding
Seeding is the Enemy's patient art. The parasite enters by mouth, wound, eye, ear, baptismal font, ration broth, lover's kiss, surgical mercy, or any other aperture the Bureau has not yet had the dignity to name. Early infestations were believed crude: worms driven under skin, a fever, visible swelling, death or rupture within days. That belief comforted border physicians, which is how one knows it was doomed.

The later forms sit quiet for weeks. Months, in village cases. The host loses weight in the places hidden by clothing. Appetite comes in fits. Sleep shortens. The pulse develops a second hesitation beneath the true beat, detectable at the throat if the examiner has a blessed thumb and the courage to keep it there. The eyes remain human. That is the obscenity. A Thrall's vacancy warns the rifleman; a Hollowed body's rattle warns the sapper. The Wormhost offers eyes that recognise you.
Earlier field catechisms stated that Wormhosts could be identified by greenish veins, abdominal swelling, and aversion to bell-metal.
Corrected. These signs describe late rupture, failed seeding, or several harmless liver complaints. The Bureau of Medicine has asked that harmless liver complaints stop being burned under suspicion of demonic incubation. The request has been filed beneath operational caution.
Villages are seeded as deposits, not massacred. This is the part civilians fail to understand because civilians still imagine the Enemy prefers spectacle. Sometimes it prefers storage. A settlement hollowed under Shadow Court husbandry may continue ploughing, trading, singing feast-hymns in cracked voices, bearing children, and keeping doors painted white. Then the order comes. The village opens.
#On Rupture
Rupture is not death in the usual legal sense. The host is already lost; the parasite merely files the paperwork in meat.
At command, the ribs flare. The throat splits or the belly unbuttons from within. Coils emerge armoured with wet plates, blind heads striking at heat, sound, prayer, motion. Some forms drag the host body like a discarded cope, still wearing the face as a ragged hood. Others burst free in smaller swarms, each no longer than a clerk's forearm, each armed with a mouth arranged like a seal press. A few remain anchored to the spine and use the limbs, producing that hideous marionette gait every veteran recognises and no recruit believes until he sees it lurching over the parapet.
The sound is worst: a tearing rush followed by breathing that has no lungs behind it. Men who survive Wormhost rupture report that the battlefield seems briefly intimate, as though the Enemy has leaned close enough to speak through someone they once pitied.
No fortification was designed to repel an enemy born already inside the wall. The Shield Paladins despise Wormhosts for this reason with a purity approaching doctrine. A locked line assumes the threat is before the shield face. Wormhost rupture makes the second rank a wound, the third rank a slaughterhouse, the fourth rank a set of witnesses nobody requested.
FIELD REPORT — SECOND-RANK HOOK SEVERANCE DRILL, FILED AFTER ████████ SECTOR INCIDENT Paladin N—— opened from sternum to pelvis during Lock-Formation. Adjacent Paladin applied hook severance as instructed. Parasite remained attached to spinal column and recited the lock-countersign in N——'s voice. The formation held for eleven seconds. Names of surviving witnesses sealed.
#On Named Incidents
Worms earned its name twice, once by geography and once by failure. An auxiliary battalion admitted for trench labour ruptured mid-assault after three days of ordinary fatigue duty. Hundreds of parasites swarmed through the sap line, chewing men into mortar for their first nests. The commander had logged the battalion as “low-risk, underfed, grateful.” All three observations were accurate. This is why accuracy without suspicion is merely a more elegant route to catastrophe.
At the Odessa Fields (Unregistered), harvesters turned Wormhost during cutting season. Scythes rose, hymn fragments broke, and the farmers split in the wheat. Parasites sprayed across the crop rows until the field itself writhed like muscle under a butcher's thumb. The Bureau of Agriculture wished to burn the grain. Tithes wished to salvage it. Purity burned both the field and the argument, which remains one of Purity's finer contributions to policy.
At Ghent, refugees admitted through the western gate ruptured in the night. Their parasites nested in the barracks rafters, feeding on sleeping men and old wood until the roof sagged with moving weight. Fire purged what remained. Records counted the event as a quarantine breach, then as a barracks maintenance failure, then as enemy action, then as all three, each stamp laid over the previous like bandages over a bite.
#On the Erratum of A.S. 195
For thirty years the public Codex called Wormhosts rare. The word was comforting and survived longer than truth. Rare things can be hunted by specialists. Rare things can be placed in footnotes. Rare things do not require every gate clerk to sleep badly beside a cudgel and a bell-metal probe.
The Bureau of Records uncensored the opposite in A.S. 195. Entire villages hollowed and seeded. Whole processions walking under cloaks with parasites curled along the spine. Refugee columns containing enough hidden rupture to undo a bastion if admitted during fog. The old word was withdrawn from operational use and reclassified as “comforting.” I admire the precision. A lie named by its function is halfway to repentance.
Previous editions classified Wormhost events as isolated parasitic atrocities.
Corrected under the A.S. 195 Records erratum. Wormhosts constitute a distributed enemy storage system using mortal communities as sealed magazines. The phrase “isolated atrocity” has been preserved for civilian sermons, where panic must be rationed like grain.
Doctrine disliked the erratum because it made evil look organised rather than theatrical. War disliked it because every checkpoint became a confession booth with knives. Purity loved it, naturally. Purity loves any fact that grants permission to close a gate.
#On Detection and Quarantine
The standing quarantine for persons crossing from enemy territory is seventy-two hours. Seventy-two hours is long enough for late-stage trembling, fever, throat-clicks, shadow-pulse, bell-metal aversion, prayer stutter, involuntary abdominal pressure, and the small wet sound that sometimes comes from beneath the left lung. It is not long enough for patience perfected by Hell.
The quarantine catches roughly one in five by the Bureau's own estimate. The other four walk through the gate singing hymns with something coiled around their spines. This figure is classified, denounced as defeatist, and used in every serious planning room west of the Line. Contradiction is policy, and in this instance policy has teeth.
Inspection methods vary by sector. Brest uses bell-metal slivers warmed over incense and pressed beneath the jaw. Przemyśl uses chant interruption: the suspect must recite the Eternal Creed while a counter-rhythm is tapped on the ribs. Irongate listens through wall pipes for a second pulse. Shipka has difficulty, because Syrion's sleep-fog slows human responses enough to make every innocent resemble a well-behaved corpse. Constantinople trusts fire too readily, which is to say correctly more often than Mercy wishes.
A false positive kills an innocent. A false negative kills a corridor. Bureau arithmetic prefers the first error because it fits in a coffin.
#On Countermeasures
The official countermeasure is early identification, controlled burning, and denial of mass shelter to unverified columns. The practical countermeasure is cruelty performed before panic can improve it. Gates close. Families are split. Children are held under lamps while mothers are asked questions designed to break both answer and answerer. Men with old scars are stripped. Women with fevers are shaved. Priests recite absolution beside inspection pits so that mercy may stand nearby while policy does the work.
Once rupture begins, doctrine shortens to verbs. Sever. Burn. Hook. Pin. Do not embrace. Do not listen if the host speaks in a known voice. Do not allow Paladins to turn inward unless ordered, because a wall that pivots becomes a door. Radiant Fusiliers fire low to cut the emergent coils before they climb. Ash Chaplains smoke the breach with relic-ash dense enough to choke human throats, on the argument that a throat still worth saving will forgive the Bureau later.
The cruelest instruction is the cleanest: kill the host before emergence if certainty reaches threshold. Certainty rarely reaches threshold. Men hesitate. They look at a refugee's face, at a farmer's hands, at a surrendered boy's cracked lips, and in that interval a parasite receives its sacrament.
#Ratification
As of A.S. 201, Wormhosts remain listed under Mortal Auxiliaries of the Shadow Court, though the phrase “mortal” now carries a taxonomic insult. They are mortal at the surface, parasitic in occupancy, demonic in command, and bureaucratically intolerable because they make every category bleed into its neighbour. Medicine wants specimens. War wants protocols. Purity wants authority. Doctrine wants a sermon in which every gate closure sounds like charity.
The Synod has provided all four.
A Wormhost is the Enemy's argument against recognition. It takes the human face, the raised empty hand, the refugee hymn, the trembling body at the checkpoint, and turns pity into a fuse. The proper response is not to stop pity. That would grant the Lie too elegant a victory. The proper response is to place pity behind iron, weigh it under bell, interrogate it by candle, and, when the second pulse answers, burn the document unopened.
