Pathfinder 1st Edition

The Pathfinder Roleplaying Game is a fantasy role-playing game (RPG) that was published in 2009 by Paizo Publishing. The first edition extends and modifies the System Reference Document (SRD) based on the revised 3rd edition Dungeons & Dragons (D&D) published by Wizards of the Coast under the Open Game License (OGL) and is intended to be backward-compatible with that edition.
