First-party rules
Tales of Mar de Oro: Native Rules
The complete first-party rules for playing in the Golden Sea.
Mid-weight tactical play built on one narrative resolution engine. The core conversation stays light; exact facing, firearms, Fortera engineering, formations, and vessel-scale decisions become detailed only when they matter.
The Native Rules are one option among several. Mar de Oro is a system-neutral setting with its own complete Native Rules, an ultralight 2d6 Resolution Bridge, and conversion support for other systems. If your table already loves another engine, keep it: the 2d6 Resolution Bridge stays the ultralight option, and the system conversions for D&D 5e, Pathfinder First Edition, Pathfinder 2e Remastered and Forged in the Dark remain fully supported.
