The Rat's castles are usually large, featuring loosely placed buildings surrounded with single stone walls and curtain gates, forming large courtyards. A large portion of the defense is assembled on the keep and around the barracks, however sporadic units also stand on the walls. There are no other forms of protection around.
Like his precursor, the Rat's economy is very basic and barely productive in any way, featuring a limited number of weapons workshops, apple farms and woodcutters along with quarries. He does protect his buildings with wells however. He mainly generates income from taxation and only buys in weapons in small quantities.
Inheriting his father's lack of skill, Duc de Puce uses purely light, inexpensive units from the barracks that make up for their lack of quality in ever-growing numbers. His mainline units are men-at-arms and conscripts, sent in groups of a few dozen troops. The Rat has wisened up however in the siege department, as he uses mantlets and catapults to provide artillery and defensive support to his deployed units.
