To prevent monsters from returning to cleared lands, mercenaries can be hired to conduct patrols. Regular patrols can prevent monsters from reinhabiting the area up to 18 miles around the stronghold. In difficult terrain (e.g. jungle, swamp, mountains), a garrison must be stationed every 6 miles.

If the PC spends additional funds on improving a cleared area, settlers may be attracted to move in. For example, the character might commission the construction of inns, docks, mills, and so on. Advertising may also be necessary. The referee determines the costs involved and how many settlers are attracted.

If settlers move into the PC’s domain, the character will receive an income of 10gp of taxes per year from each settler.
