CROWN & CRUCIBLE

Common-born beginnings. Inherited power. A war that does not wait.

Historical Medieval Sandbox (c. 1150–1350) Strict Zero-Magic Canon Seven Isles of Aethelgard Native macOS Universal Bundle Pre-Release Candidate Staged

Across the wind-swept archipelago of Aethelgard, the Crown Reckoning marks the year 487. A hundred years of intermittent raids, border skirmishes, and uneasy truces are collapsing into open civil war between the royal seat of King Aldous III at High Cairn and the rebellious Iron Council of Dunhollow.

You do not arrive as a prophesied champion, a sorcerer, or a knight in gilded plate. You play as Rowan—an experienced, common-born man-at-arms with calloused hands, a dented kettle-helm, an iron arming sword, and an empty coin purse. In Aethelgard, danger wears mail and gambeson, and the most devastating weapon is not a spell, but a winter grain embargo.

Systems Architecture

Pillars of the Living Kingdom

Nine uncompromising systemic pillars engineered for material realism, economic consequence, and deep player agency.

World & Spatial Design

17 Enterable Parish Building Interiors

Every functional building in Stonecross is a physical, enterable room on a dedicated non-overlapping sub-map: Master Odo's Forge, Beatrice's Bakery, Reeve Alden's Manor, Thornfield Watermill, the Tithe Barn, Weaver's Loft, the Chapel, Toll Gatehouse, and Barrows Watchpost. Engineered doorway threshold collision zones guarantee zero bounce loops or spawn jams.

Living World Simulation

4-Phase Living Diurnal Schedules

Inhabitants do not stand motionless in the rain. Across Dawn, Midday, Dusk, and Night, townsfolk live real routines: blacksmiths strike hot billets at sunrise, carters haul timber at noon, laborers drink bitter ale at the tavern by dusk, and farmsteads bolt their shutters against nightfall.

Career Progression

Six Grounded Feudal Livelihoods

War is expensive, and violence is not the only occupation. Earn honest silver by hiring out your muscle: threshing rye as a Farmhand (+8G), stoking bellows for the Smithy (+14G), walking the palisade on Town Watch (+10G), hauling stone in the Quarry (+18G), stalking deer as a Crown Forester (+15G), or gathering roots as an Herbalist (+12G). Accumulate capital to purchase formal tenancy leases with daily dividend yields.

Feudal Mercantilism

Systemic Economy & Rule 13 Assize of Bread

Markets simulate local supply and demand. Rowan carries goods within physical cargo tiers (3-sack Foot Pack, 10-sack Pack Mule, and 30-sack Carter Wagon). Under the Rule 13 Royal Assize of Bread, the Crown caps staple wheat at ≤ 18 Gold in royal markets like Stonecross and High Cairn to prevent starvation, while rebel Dunhollow suffers runaway inflation past 30 Gold.

Narrative Engine

37 Reactive Branching Conversation Trees

A living web of 28 unique village characters and 9 historical landmark inspections. Townsfolk react dynamically to the advancing War Clock, your standing with the Crown or Iron Council, unpaid tavern tabs, and visible battle wounds. You are never flattered as a mythical hero; you are a working man-at-arms whose repute must be earned contract by contract.

Interface Design

Diegetic 5-Tab Commoner's Notebook

Pressing [J] opens Rowan's folded parchment journal: 1. What I've Learned (historical annals and church lore), 2. Papers I Carry (royal warrants, tax receipts, safe-conducts), 3. What People Say (overheard tavern rumors and market chatter), 4. Work & Contracts (feudal military and carter bounties), and 5. Debts & Standing (faction favor, renown, and active debts).

Tactical Combat

Consequential Steel-and-Leather Combat

Precision melee offense across 5 historically accurate weapon classes (Arming Sword, Greatsword, Dagger, Hunting Bow, and Poleaxe/Spear) coupled with real-time defense. Every swing burns stamina and dulls blades; unblocked blows gouge armor plates. Defeat does not miraculously restore you: you awaken at 50% HP, nursing Bruised Ribs with repair bills and a medical rescue debt recorded on the chapel slate.

Retinue & Social Bonds

Retinue Companions & Sellsword Morale

As Rowan's chivalric renown rises, hire up to two retinue companions (such as veteran crossbowmen or shield-bearers). Retinue members require daily food and wages; neglected wages lower morale and risk desertion, while well-maintained retainers grant active combat synergies and tactical flanking.

Locked Canon & Setting Grounding

Strict Historical Canon: Zero Magic, Zero Supernatural Forces

Built under strict compliance with the 12 Locked Canon Rules and Rule 13: zero spells, zero dimensional rifts, zero magical portals, zero monsters, zero chosen-one lineages. Every mystery, crime, and war consequence is rooted in authentic 1150–1350 medieval material culture, common law, and feudal institutions.

Historical Lore • Oren of Halewick (CR 487)

The Seven Isles of Aethelgard

As recorded in the surviving parchment folios of The Chronicles of Aethelgard, the archipelago comprises seven distinct regional provinces:

Maroven

The Royal Heartland

Seat of King Aldous III at the walled citadel of High Cairn. Enforces royal river tolls, the King’s Highway, and statutory bread price controls.

Caerwyn

Chivalric Border Marches

Ancient river gorges, stone watchtowers, and weathered tournament pavilions governed by proud marcher lords torn between loyalty and defiance.

Rusk

The Iron Ridge

Dark pine hills, limestone quarries, blast furnaces, and deep iron pits. Homeland of the rebellious Iron Council of Dunhollow and veteran sappers.

Ordel

The Breadbasket Valleys

Vast rye fields, monastic tithe barns, and watermills. Feeds the armies of both factions; prime target for wartime blockades and grain seizures.

Terveth

The River Estuaries

Tidal channels and timber wharves commanded by the River League bargemasters, profiting from contraband trade while evading royal duties.

Sere

The Windward Coast

Rugged slate cliffs, herring smokehouses, and hardy fishing hamlets. Fiercely independent pilots who provide salted provisions across stormy straits.

Vey

The Outer Marches

Dense birch taiga, overgrown royal redoubts, and ancient burial barrows. An untamed border where outlaws, deserters, and hermits take refuge.

The Four Great Factions of CR 487

Power & Ideology

The Royal Crown: Feudal monarchy defending the King's Highway and grain ceilings • The Iron Council: Rebellious mining lords resisting royal river taxes • The River League: Merchant bargemasters profiting from wartime smuggling • The Common Observance: Monastic order maintaining parish tithes and shrines of St. Aveline.
