Nobis: The City-States Player's Guide

A fantasy campaign setting for version 3.5 of the world’s most popular role-playing game and other OGL products, focused on the City-States region and the sprawling city of The Gates. Players find new options for character creation and development, including the mongrel playable race, Simplecraft arcane power, a class-neutral Fencing Discipline, and integrated black powder firearms. A Reputation System ties role-playing and notable deeds to game play. The setting combines political strife, secretive underworld powers, noble freedom fighters, and scheming politicians, with players choosing how their characters respond to the conflict between freedom and tyranny.
