Demon-Sign Chalk
White on the rail, warm over the heart
A maintenance consumable carried over the heart: Guild chalk marks rails no man should walk alone after dark. Doctrine denies theological standing; witnesses report warmth.
Codex Ref. III.2.04-859
Gauge Standardization Decree
One measure for the iron, four thousand graves for the agreement
The A.S. 136 decree imposed 1,435 millimetres on Dominion rail and ended the Gauge War by threat of closure. Three years of relaying cost approximately four thousand lives; Engineering supplied the measure, labour the graves.
Codex Ref. XIII.1.136-001
Gauge War
Forty years to agree on the distance between two rails
A.S. 96–136 rail-standardization conflict in which rival gauges starved bastion corridors until Engineering imposed 1,435 millimetres and labour paid in hands, hunger, and four thousand dead.
Codex Ref. VII.2.10-136
Guild of Rails
The iron road permits the war to arrive
Licensed brotherhood of track, gauge, junction, ballast, bridge, and schedule; the Guild moves the Dominion’s war and charges extra when physics objects.
Codex Ref. XII.44.01-001
Iron-Blood
The rail remembers; the Bureau recommends observation
Iron-Blood names the rail trade and the change its veterans claim. My A.S. 186 inspection records Grosz's grey hands and hard grip; six Purity inquiries found no evidence of supernatural contamination. The cause remains unfiled.
Codex Ref. XII.44.02-001
Prussia
The state died; the timetable kept breathing
Prussia is the dissolved northern kingdom that survived as method: rail clocks, cold clerks, officer corridors, East Prussian gun-bronze, and the north's habit of arriving.
Codex Ref. II.4.09-095
Saint Vandrail
The rail remembers; the hammer asks whether it tells the truth
Saint Vandrail, uncanonised and undenied, is the Guild of Rails’ hammer-fisted patron of track, gauge, night patrol, iron-blood, and useful delay.
