 "content": {
  "character": "The surviving stretch runs about a third of the way into the belt before it disappears. The far section, past the ambush point, was fired and sank; in dry years the stone core surfaces as a line of humps with no road between them.",
  "legacy": "Zegtuzsos guides still use the visible stretch as a landmark and refuse to walk its length. Imperial engineering schools teach the causeway as the founding failure of the discipline - every rule about escort intervals and section-holding on military road comes from what happened here.",
  "overview": "A raised roadbed of stone core and fascine shoulder, built to carry the Grand Army across the Ihtaa Fens in a single season. Four years of construction. Eleven days of use."

  "character": "Effectively unstormable by the standards of the age and effectively unstarvable in the short term, since its water was internal and its stores deep. What it could not do was end. There was nowhere further to withdraw to and nobody left to relieve it.",
  "legacy": "Still inhabited. Garrisoned by the Empire under the terms of the surrender, and administered by a Mulaagjun, which makes it the clearest physical statement of what the settlement of 1305 actually was. In Saarotsos usage the name has drifted into an idiom for an ending everyone survived, which Zegtuzsos speakers find intolerable.",
  "overview": "A highland fastness built into and under a mountain, holding its own springs. The last seat of Zegtuzsos independent authority and the place the surviving Mulaagjuns gathered after Urtkaa.",
  "role_in_the_war": "Invested in the winter of 1303. Kaemisyol declined to assault it and instead built rings of fortified road around the mountain over twenty-six months. The delegation that went to Vusokaar under the white-scorched banner in 1305 came from here."

### The Ihtaa Fens  (location · wetland, canon id: locations-ihtaa-fens)
Seasonal. In high summer the peat firms enough to bear infantry on foot but not carts; in the wet season the whole belt becomes impassable and the channels move. Fever is endemic. Revakgol lost more soldiers to the water than to the Zegtuzsos in every year of Phase II. A belt of standing water, peat and reed running roughly east-west behind the Medestul, wide enough that no army had ever crossed it in force and shallow enough that it could not be sailed.

The Zegtuzsos did not defend the fens. They lived on the far side of them and let the ground do the work. The Drowned Years, 1274-1286. The …

### The Siege of Kaagaat  (military_conflict, canon id: military-conflicts-siege-of-kaagaat)
The Last Clutch The refusal to assault is the tactical fact underneath the political choice the parent entry already records. Storming Kaagaat would have killed the surviving Mulaagjuns, and Kaemisyol wanted the Paathur system intact and legitimate enough to govern through. A bastion taken by storm has no one left with the standing to surrender it.

The delegation went to Vusokaar in 1305. The Paathur system was preserved beneath the Dovahrein; imperial garrisons were admitted at key sites; the Mulaagjuns kept authority over Zegtuzsos villages. Kaemisyol invested it in the winter of 1303 and …
