Research

A sharp blade outlasts a dull army, and a full ledger outlasts them both. The scholars of the Laboratory keep a tree of study in four branches: Warfare, Seafaring, the Shadow Arts, and Prosperity. Each line of that tree is climbed level by level, each level a named study with its own price and its own reward. Research is slow and costly, but no raid can undo what has been learned.

The Scholar's Bench

Only one advancement may be studied at a time per settlement. Every level of every line is its own study, individually named and individually priced: the first rank of Spearcraft is the Levy Drill, a cheap afternoon's work, while the tenth is a costly oath sworn by the whole line of battle. The reward of each study is permanent and cumulative. A fifth rank does not replace the fourth; it builds upon it, and battle forecasts read the settlement's current ranks, so forces already mustered benefit the moment the study completes. Every completed level also raises the island's prestige.

Lines grow out of one another. Shieldwork asks for a rank of Spearcraft first, Siegecraft for a schooled corps of Bowcraft fletchers, and each branch's crowning work for mastery of the lines beneath it. These prerequisites only gate the start of the next study. Nothing a settlement has learned is ever taken back, not by raiders, not by curses, and not by a Laboratory that later falls to siege.

Knowledge Bound to the Bench

Research belongs to the settlement where it was achieved, not to the Governor's domain at large. Each Laboratory houses its own instruments, prototypes, and calibration records, and none of them survive a voyage across open water. Every colony therefore requires its own Laboratory and its own programme of study, and a Governor who expands quickly should plan the order of advancements carefully, since a young colony rarely needs the same studies as an established stronghold.

Master Quill
Master Quill: Margin note
Research is the slowest pillar of governance, but the most enduring. A breakthrough earned on one island cannot be crated and shipped to another, and it cannot be stolen either.

The Laboratory's Gates

The tree is arranged in tiers, and each tier waits on the Laboratory. A modest bench opens the first studies of every branch; the deepest tiers, where the Great Works are drafted, demand a Laboratory of the highest orders. Some long lines also set their own deeper gates: the early ranks of Spearcraft come freely, but its master ranks ask for a taller bench before the scholars will attempt them.

ILaboratory 1–27
IILaboratory 46
IIILaboratory 86
IVLaboratory 123
VLaboratory 14–184 (the Great Works)

The Laboratory does more than open doors. Its scholars work faster as the bench grows: each Laboratory level trims research time by 1%, up to a saving of 15%. Levels raised beyond the tier gates are never wasted.

Warfare

The branch of drilled ranks and broken walls. Spearcraft arms the levy and opens the way to SpearfightersSpearfighters, a Governor's first real defenders. Shieldwork hardens the garrison and, deep enough, fields the elite SwordsmanSwordsman. Houndcraft raises Guard HoundsGuard Hounds at the Kennels, Bowcraft arms ArchersArchers, and Drill Yards muster every recruit faster. Siegecraft builds the engines that break walls and claim territory, and Banner Discipline steadies the whole island's defence. The branch crowns itself in The Master-at-Arms.

Marshal Voss
Marshal Voss: Field order
Spearcraft first, then Shieldwork. An army that can hold ground survives long enough to learn everything else.

Seafaring

Speed on the open water wins wars before they begin. Sailcraft quickens every vessel in the fleet and unlocks the heavier hulls, from the Large Merchant ShipLarge Merchant Ship to the Large WarshipLarge Warship and the Colonisation ShipColonisation Ship. The rest of the branch is the navy's paperwork made deadly: The Harbour Watch teaches warships to hold station over their own shore as a patrol, Victualling keeps those patrols provisioned and on station longer, and Letters of Marque sanction the blockade, the ambush of cargo in open water. Convoy Masters squeeze yet more speed from a fleet and teach it to sail in company — the signal books behind a combined attack — and The Grand Admiralty crowns the branch.

Faster ships mean shorter supply runs and quicker reinforcements. Sailcraft pays dividends long before the first Large Warship is commissioned.

The Shadow Arts

Knowledge of the enemy is as valuable as any weapon, and some of it is best taken quietly. Espionage trains spies to slip past defences and return with richer intelligence; the Espionage chapter covers the missions themselves. Night Landings teaches crews to touch sand without a sound, which is what permits a plunder run at all. False Colours sharpen the getaway odds of those runs, and The Spymaster's Ring crowns the branch for Governors who prefer never to be seen.

A few points of production sound like pennies until they compound across every hour of every day. The Prosperity bench is the only study that funds its own successors.

The Great Works

Each branch ends in a single crowning study, a Great Work: one level, a princely sum of gold, and days of scholarship. The Master-at-Arms sharpens the whole island's attack and defence, The Grand Admiralty hastens every hull in the fleet, The Spymaster's Ring blesses spy and plunder alike, and The Royal Charter enriches every stream of production and coin. A Great Work asks for mastery of the lines beneath it and a Laboratory of the highest orders, and like every study it belongs to one island alone.

What Research Unlocks

Some studies do not sharpen an edge; they teach the island an art it simply could not practise before. These arts are checked on the island that launches the venture, so a Governor with many harbours must school each one that means to use them.

Several advanced units also wait on the bench. The roster below shows which advancements gate which forces.

Master Quill: Margin note
Research can be nudged along at real cost. An old guild seal will shave time off a study in progress, but such rarities are scarce by nature, so no programme of study can be bought outright. It should not be delayed either: every day without a Laboratory is a day rivals grow sharper while one's own forces remain unchanged.

Common questions

Does research apply to forces already trained?

Yes. Battle and voyage forecasts read the settlement's current research ranks, so existing forces benefit the moment a study completes.

Does one island's research help another island?

No. Research belongs to the settlement that completed it. New colonies need their own Laboratory and their own studies, and abilities such as plunder runs, patrols, and blockades are checked on the island launching them.

Can research be lost or stolen?

Never. Raids and plunder take stores, not knowledge, and prerequisites only gate the start of the next level. What a settlement has learned, it keeps.

What should be studied first?

Spearcraft and Shieldwork give the earliest defensive return, and the cheap first ranks of the Prosperity lines quietly pay for everything after them. Sailcraft becomes urgent once merchant routes, raids, or colonisation start shaping the realm.
