A tabletop RPG setting is the place where play happens. It is the map, the factions, the recent history, the strange technologies, and the questions that characters spend their time answering. A setting is not the same as a ruleset. The rules tell you how to resolve a sword swing or a negotiation; the setting tells you why the sword is there, who wants the negotiation to fail, and what everyone stands to lose.
What is a tabletop RPG setting?
At minimum, a setting gives a group a shared imaginary space. At its best, it also gives them tensions to explore: colonial powers against indigenous peoples, faith against engineering, old crowns against new wealth, and ordinary people caught between forces they did not create. The world should feel coherent enough to support improvisation and rich enough to reward curiosity.
Settings can be original, like Mar de Oro, or adaptations of historical periods, novels, or film. What matters is that the table can answer practical questions quickly: Who runs this port? What happens if the airship lift fails? Why does that faction want this artifact?
What does system neutral mean?
A system-neutral setting, sometimes called system-agnostic, is written so it can be paired with different rules engines. It describes the fiction in terms of role, capability, scale, pressure, and consequence rather than in terms of a specific game's stats, classes, or action economy.
Mar de Oro is system-neutral. The world comes first. The Setting Guide, GM Guide, and web codex describe what characters and factions can do in the fiction. The System-Neutral Adaptation chapter then shows how to express those ideas in D&D 5e, Pathfinder First Edition, Pathfinder 2e Remastered, Forged in the Dark, or any other system.
Is Mar de Oro a complete game or a setting?
Mar de Oro is a system-neutral setting with its own optional Native Rules. You can also use supported external conversions or the ultralight 2d6 Resolution Bridge. Its world of Aeon, the Golden Sea, the airships, and the Fortera field remain the same whichever path you choose.
The Native Rules offer a first-party way to play; conversion notes support other games. Choose the approach that suits your table.
How do I start playing?
- Read the Quickstart, The San Telmo Incident, for a complete 3–5 hour introductory adventure.
- Download the free Setting Guide or One-Page Primer from the Resources page.
- Choose the Native Rules, the 2d6 Resolution Bridge, or an external system with the System-Neutral Adaptation chapter.
- Use the published conversion notes for D&D 5e, Pathfinder First Edition, Pathfinder 2e Remastered, or Forged in the Dark if you want a head start.
At the table
Start with the fiction, not the mechanics. Ask the players what kind of crew, company, or expedition they want to be, then choose the system that best supports that style of play. The setting will meet them there.
