Information about the game setting:
The game setting is called The Hex. The Hex is a fortified city on a large navigable river. It's named for its 6 ruling families, which no one in living memory has seen. In practice, it is ruled by the guilds and the Low House of land owners. The Hex is a low-fantasy setting; magic exists, but is seldom overtly seen in this age. A previous forgotten age dabbled more in dark magic; this civilization is buried in a layer of ash under The Hex.
