From the inside cover:
This volume is an introduction to the world of Mythras, designed for game masters wishing to run adventures in this setting. It focuses on a particular part of this world: the great city of Valoria, the foremost stronghold of humankind. Here you will find details of the geography, culture, social and political structures of Valoria; descriptions of its many districts and neighborhoods; and a guide to the lands immediately surrounding the city, for those bold enough to venture beyond its fortified walls. The materials here are presented in a system-agnostic format, designed to be easily adaptable into your favorite fantasy RPG rules system.
This book has been produced as part of the backer rewards for Dwarven Forge’s epic Castles Kickstarter campaign. It is an abbreviated version of a future sourcebook that will further detail Valoria and Mythras, the fantasy setting created by Dwarven Forge’s founder, Stefan Pokorny--the place where for decades he has set his famous adventure games.
If you enjoy your visit here—more awaits! The future sourcebook will include extensive additional material on both Valoria and the great continent of Mythras, enough for many years of memorable gaming. Enjoy!
