Gary Gygax's World Builder

A reference volume for designing and expanding fantasy game worlds. It provides definitions, lists, tables, and charts covering trees and herbs, terrain, government, everyday materials, weapons, armor, magical gems, and spell components. The information is largely system-neutral, with additional rules and guidance for the d20 and Lejendary Adventure systems. It is intended for game masters and setting creators building detailed fantasy environments.
