Romarra is a giant planet, orbited by dozens of Moons, most of which are planets in their own right, and all of which can support life at least some type of life. The planet has over 100 continents, and thousands of Cultures and Groups and Places of Interest across its surface. The intelligent Races of Romarra are far more tied to their cultures than race. Monsters arise from the depths of Romarra constantly, demanding that even in times of peace heroes are always needed.
There are a few changes to Romarra commonly called House rules that separate it from standard pathfinder rules. Most of these are to bring various character builds in line, and alter the flavor of the world.
