The Armory & Warfare of Merretia

Adopted 2026-07-14 from the armory-and-warfare design council (COUNCIL/armory-and-warfare-council.md), with Logan’s rulings on the three open questions. This file is the canon source of truth for weapons, arms manufacture, and warfare doctrine; the tabletop Player’s Handbook Equipment chapter and the Master’s Guide warfare section render from it.

Identity in one line: Merretia fights with the slam-and-hush of coiled steel and the flare of a kept promise — industrial attrition periodically detonated by something closer to divine violence.

The load-bearing fact under all of it: magic is a rare, quickly-exhausted elite (roughly one true practitioner in several thousand, and every Working bills the body or the self — see 02-DISCIPLINES, 06-HISTORY). So the disciplines cannot be how armies fight. A battlefield is common soldiers with oath-metal blades and charged coil-arms, threaded with a handful of terrifying, exhausted channelers — the divine violence that decides the ninety seconds that matter.

1. The Martial Line — Oath-Metal, melee-primary

Oath-metal (Kardun drun-vel) is not magic; it is a contract. A vow is spoken into the pour at the forge, and the blade’s temper holds only as long as the wielder keeps that vow. It stays melee-primary and rare — reserved for blades, armor, and relic weapons, never diluted into mass-issue barrel stock. Scarcity is the point.

The iconic silhouette — the Kelvath (“vow-blade”). A slim, asymmetric single-edge glaive-sword (khopesh-meets-rapier, not a katana), the spine inlaid with a hairline drun-vel channel, the guard a broken ring — Kardun smithcraft never closes a circle, because a closed ring is a dead vow. The tell: on the draw, the etched vow flares warm gold for half a second. This is Merretia’s answer to the lightsaber-hum, the sound-and-sight that says this world at a glance. It is the Duelist’s signature weapon (RULEBOOKS/PHB-04f).

The supporting martial line:

Vardrun — an oath-pike / true-weight lance whose head keeps a measure of raw unshaped mass, so it hits like something twice its size. The Ironclast’s breacher weapon.
Grief-hooks — paired sickle-glaives, a funerary tool turned skirmisher’s weapon; culturally loaded, favored by duelist-skirmishers.
Marshal-irons — plain steel city-guard batons, deliberately unglamorous and institutional. Not oath-metal: the point is that the law’s everyday hand is mundane.
Standing shields — bound-light-filament bucklers, a Founding-derived tech stiffening (not a Working), so non-casters get magic-adjacent toughness without magic.

2. Ranged Arms — the Arc-Lock family

There is no gunpowder in the metropole’s arms. Sulamir electrified before it could have chemically industrialized, so the ranged weapon of this world is a magnetic-coil arm fed by a swappable, palm-sized buried-sun cell — descended in-world from magnerail engineering (the same coil-and-rail principle that moves the trains, miniaturized). It fires a physical slug, not an energy bolt (Logan’s ruling): colored energy discharge stays the exclusive tell of a real channeler, so a soldier learns to fear the color of a stranger’s eyes more than any gun.

The naming architecture (one family, four tiers):

Arc-lock — the mechanism class (any coil-arm).
Vow-Rifle — the flagship: individually oathed, guild-forged, House- or unit-liveried, the barrel etched with its service record. A captive Weight-focus-stone sliver briefly collapses the cell’s charge into the slug; it fires with no muzzle flash and no smoke — a compressed THOOM like a door slamming in a vacuum, then a half-second of ringing silence as the displaced air rushes back and the barrel-etching flares gold. That silence is the signature.
Coilbow — the cheaper, older-format cousin: a crossbow silhouette, capacitor-assisted, its amber capacitor-glass draining visibly as it fires. Frontier, militia, and civilian tier.
Rail-lance — a two-handed, long-coil-throat longarm for range; guild-militia heavy.

Every arc-lock carries a cheap, mass-stamped striker-ward — a dumb, impersonal sliver of focus stone that stabilizes the shot. It is the industrial echo of a wielded Focus Stone, and it is the detail that makes this magitech rather than mere electronics. Oath-metal is reserved for relic-tier Vow-Rifles only (House-champion, Marshal-Captain status weapons); mass-issue barrels are mundane Kardun alloy.

Tactical constraints (locked): a cell holds 8–12 shots before it is cooked; cells swap in the field but recharge only on the buried-sun grid — which makes the grid a battlefield objective. Sustained fire risks coil-throat overheat and backfire, so doctrine fires in called volleys, not sprays.

3. Gunpowder — the marginal tech, and the seed of the cycle

Gunpowder exists, but it is crude, marginal, off-grid, and quietly suppressed (Logan’s ruling). The metropole disdains it; the guilds and Houses fear it, because it is the one arms-tech they cannot control — it needs no grid, no license, no channeler to recharge it. So it lives at the edges: the frontier, the homelands the grid never reached, rebel hands, and the hidden workshops of people the powers-that-be would rather not arm.

Its role is precisely the one nothing else fills: the grid-free equalizer. Where a coil-arm dies the moment it is cut off from Sulamir’s infrastructure, a powder-arm does not care. Historically, firearms ended the knightly caste; the Merretian elite are right to fear the same.

4. The two-tier magic economy

Magic’s rarity makes “a channeler on every firing line” impossible, so magic’s products circulate while magic’s supply stays a scarce service.

Channeler-borne weapons — full discipline power, drawn on the wielder’s own Strain or Fray (RULEBOOKS/PHB-06): Current’s galvanic lance, Weight’s anchor-hammer, Unmaking’s corrode-brand and open flame, Binding’s oath-net and ward-plate. Binding is the highest strategic-value discipline in a fight for a fortification (it breaks and prevents sieges), and Binding resists Unmaking almost categorically, a built-in counter-tech that makes oath-metal gear hard to corrode-brand.
Stone-tier ordnance — the democratized layer, usable by any non-caster: arc-carbines (Current, 1–3 bolts per stone-cell), grav-shot (Weight, mass-gaining armor-piercing ammunition), cinder-flasks (Unmaking thrown incendiaries), single-use oath-nets (Binding). These are pre-charged by a trained channeler at a licensed guild workshop and are finite and non-self-recharging — a spent stone is inert glass until a practitioner refills it. A channeler need not be present at the trigger, but is always needed at the refill — so recharge stations and stone-cutting guilds are the strategic chokepoint armies fight over, the ammo-depot of this world.

5. The visual grammar of arms

Governed by the disciplines’ own law (02-DISCIPLINES): Order channels EMIT light; Chaos channels STAIN or transform surfaces.

Binding runs a thin yellow seam along an edge (not a glow). Current arcs cyan with ozone and hot copper. Weight doesn’t glow at all — it simply gets heavier, and the wielder’s stance shows it. Unmaking visibly rusts and flakes in real time.
Chaos inverts the rule: Heart-stained blades blush and won’t let blood clot; Dream blades go matte and light-eating; Growing weapons weep sap and grow moss.
Three legible over-grammars that never get confused on a field: warm-gold shimmer = oath fidelity, cold blue-white = raw current/charge, the nine discipline colors = active casting.

6. Warfare doctrine

Army shape — the Wedge, not the Wall. Density is death against Weight-craters and Heart-cascades, so the Line (regulars in arc-locks and oath-metal-edged panoply) fights in staggered, chess-square interval — “keeping your Fray-distance,” a habit that has outlived its cause into plain doctrine. Above the Line, the Thread: practitioners deployed individually, each guarded by a Cage of 6–10 elite non-casters whose only job is keeping their channeler alive for the ninety seconds that matter. Commanders hoard channelers like artillery, count “flashes” the way older wars counted cannon volleys, and feint to bait an enemy channeler into casting — and exhausting — early. Above both, the Sky: buried-sun airships for recon, magnerail interdiction, and rare decisive bombardment.

Three different wars.

Open-field / House / homeland war — the wedge-and-Thread game, won by whoever controls the magnerail junctions (logistics) and the recharge chokepoints (ammunition).
Frontier and Kardun-keep war — old-fashioned siege: starve, breach, or crack the gate with a Weight-channeler, because the frontier has no Dome. This produces real doctrinal friction when Dome-city veterans (who have never seen a wall breached) fight beside frontier garrisons who live that grind.
Dome war — the setting’s signature, because it barely happens. Per the corrected canon of the Dome (below), Sulamir cannot be conventionally besieged or bombarded to any effect, so no one has tried in living memory. The real threat under the Dome is the Seepwar — the fight against Hollow incursion, which the shield does nothing to stop because the Hollow is an absence, not an attack.

The Dome, corrected (Logan’s ruling)

Refining 10-TECHNOLOGY §1.5 and 04-CONTINENT §7: Sulamir is the economic and technological powerhouse of the continent — its “1960s-USA” — and is emphatically not cut off. The magnerail runs trains out to the other continental cities for trade and travel, through the formal gates and the Marshal corps’ protocol. The Dome is a hard energy shield against all conventional attack and against all nine disciplines (it is not a selective filter that lets some magic through — the council’s “Chaos leaks” guess is rejected). It has finite durability: ordinary armies and artillery cannot dent it, but sustained overwhelming assault can break it — on the order of a kaiju pummeling it for hours. The one thing that bypasses it untouched is the Hollow, and consistently so: a shield stops incoming force, and the Hollow is not incoming force — it is reality thinning at the seams from within. “The Dome holds against everything but the Hollow” remains true, for the right reason.

7. Arms manufacture and control (the political economy)

Who controls the arms is who holds power. Oath-metal is Kardun smithcraft, sold to the great Houses and the Marshal corps through intermediaries. Stone-tier ordnance and the recharge network are held by the licensed guilds and the Council of 18’s appropriated Binding orders — the same institutions that maintain the grid and the Dome. Coil-arms are artificer-guild manufacture, mass-issued to Marshal and House forces. And gunpowder is the one no one licensed — which is exactly why the powers-that-be fear and suppress it, and exactly why it will inherit the world.

8. Open questions

The exact draw-weight of the great Houses’ private arsenals, and which House pioneered the Vow-Rifle.
Whether any Founding-era energy weapon exists (a true “blaster”) as a legendary/relic exception to the kinetic-slug rule — a hook, not a standard.
The frontier powder-smiths: who they are, which province shelters them, and whether the Council of 18 has an active suppression program.
How the Seepwar is actually fought under the Dome (feeds 14-KAIJU-AND-HOLLOW.md and the Master’s Guide).
