A medieval knight, recognized by the king for his battlefield performance, is offered an unusual commission: sail to an uncharted island and build a settlement there, commanding both the military and the economy from scratch. Start with a wooden fence and a small fort on a coastal strip. Use trade and farming to generate income, then invest that income into stonework, archers, ballistas, and trained soldiers capable of holding off the endless waves of enemies that will come for the settlement. Once the colony is sustainable and the army is strong enough, push outward — take enemy outposts, claim their walls, and turn them into more sources of revenue for an empire that began with a ship and a charter.
