From publisher blurb: Welcome to Demesne! Demesne is a rework of the Downtime System, giving it a new framework and features. This is a great way to simulate your character's growing criminal guild, a business empire, or arcane university. These organizations have a definitive and powerful impact on characters, granting them skill bonuses and special abilities. This expansion, Captains of Culture & Commerce, introduces new aspects to the game which make it far more indepth and viable to a different number of character types. This book includes thirteen new resources (and associated buildings to produce them), and new rules for religion, hosting events, and more. Lastly, this new expansion features new rules for producing ships...floating downtime assets which can carry goods far and wide. These rules also include a simple set of rules for Naval combat and many of the circumstances that go along with it.
