Mar de Oro was built from the deck up. The Golden Sea is an inland ocean ringed by powers that cannot afford to ignore it. Ships carry mail, money, prisoners, treaties, and saints. A captain with a fast hull and a loose letter of marque can become a hero to one nation and a pirate to another. That makes the setting a natural home for naval TTRPG campaigns.
A naval campaign does not require a custom ship-combat minigame. The setting gives you the stakes: blockaded ports, rival admiralties, privateer safe harbors, and the constant arithmetic of supplies, crew loyalty, and weather. Your existing rules engine resolves the action; Mar de Oro supplies the reason the action matters.
Ships as characters
In a naval campaign the vessel is a shared character. She has a name, a history, a reputation in port, and a list of things she will not do. The crew know her moods. The officers know her debts. A ship can be brave, unlucky, haunted, or beloved. Let the players name her early and refer to her often.
- Captain: owns the mission, the blame, and the letter of marque.
- First mate / sailing master: keeps the crew fed, paid, and out of mutiny.
- Master gunner: speaks for the cannon and the powder magazine.
- Engineer or sky-wright: on airships, the person who keeps the Éterlumin system breathing.
- Surgeon, chaplain, or signal keeper: the moral and medical spine of the crew.
Three naval campaign frames
- Privateers and letters of marque: sail under a flag that pays you to hunt its enemies, then live with the legal ambiguity when peace breaks out.
- Blockade runners and smugglers: move people, goods, and forbidden books past navies that would rather sink you than inspect you.
- Exploration and charting: the Golden Sea still holds unmapped reefs, ruined signal stations, and islands whose names are older than any empire.
At the table
Start the campaign in port with a problem that only a ship can solve. Let the players choose the vessel before they choose their characters. The ship becomes the reason the party stays together.
