From publisher blurb:
Geshtei Castle, the capital of Gerium Province and a stronghold of the Gerium Legion, sits on the Thard River along the western border of the Thardic Republic. Although considered something of a backwater, the town is notable for its strategic position and rich agricultural lands. A feud brewing between the magistrate and marshal threatens the settlement's peace and prosperity.
The Geshtei Castle article describes the settlement's history, government, religion, economics, and military forces. Details are given for some of the local craftsmen and other locations in the settlement. Includes a full description and color floor plans for the keep, along with color GM and player maps of the settlement. Also included is a 2-page expanded description of Geshtei's busy milling operation.
