Priest Adin looked at the wheat and imagined a manor with windmill grinding stones in his mind. Without a windmill or grinding stones, how can it be called a manor? Hmm, the design of the windmill isn't difficult for him, but obtaining various wood and iron fittings might be challenging. Given the current state of primitive production on Cuba Island... Perhaps the main area of the Kingdom of the Lake to the west, the wealthy "civilized" place where the Devil's Apostle resides, could provide what's needed?
