I am working on three region books a the moment for Wandering Heroes of Ogre Gate, which will each become PDFs. They will cover the areas of Hai'an, the Kushen Basin and Li fan. Once I finish those I intend to do 1 for the Zhan Dao Empire.
These PDFs will be released incrementally based on material I develop for my own campaign. The reason for this is I really want to run through all the locations as much as possible prior to releasing it. That means I will need to create the material for my table first.
The Wandering Heroes of Ogre Gate rulebook will contain a rough overview of the major areas on the map, with a focused gazetteer for the Banyan Region, which is a kind of frontier inhabited by martial sects, bandits, etc. The Gazetteers for other areas will appear in the PDF releases.
The PDFs will have plenty of gameable content, but we are not treating that content as canon. This is partly because we expect many GMs will flesh out many of these areas on their own, and also because we don't want to create headaches for people. The PDF Gazetteers should be viewed more as suggestions that the GM can incorporate into his or her campaign but doesn't have to. They can ignore any content they want, make changes, etc. While this is always an unstated assumption in RPG books, we are just trying to make clear that there is no such thing as official canon with any Bedrock book, particularly with anything released for Wandering Heroes of Ogre Gate. The GM is the final authority on what content makes it into their personal version of the setting.
The PDFs will include a gazetteer, NPCs, new Kung Fu techniques, new rituals, new monsters and general cultural information.
Here are the tentative titles for each one:
Batuud: Heroic Tribesmen of the Kushen Basin
Songs of the Southern Lands: Guidebook to Hai'an
Strange Wonders of Li Fan
We will also be releasing the following full books:
Ogre Gate Inn (Adventure)
Profound Masters of Ogre Gate (Rules for higher level play)
