To prevent monsters from returning to cleared lands, mercenaries may be hired to conduct patrols. These patrols can cover a maximum radius of 18 miles around a stronghold (6 miles, in inhospitable terrain such as swamp, mountains, or thick jungle). If the area to be maintained is larger, additional garrisons must be stationed at intervals.
The PC may wish to attract settlers into a cleared area. In addition to ensuring the safety of surrounding lands, the character will have to fund construction of other buildings (e.g. accommodation, commercial facilities, transport infrastructure, etc.) to attract settlers. Advertising may also be necessary. The referee will determine the costs involved and how many settlers are attracted.
If settlers move into the PC’s domain, the character can expect to gain 10gp of taxes per year from each settler.
