External Plots
It's possible to buy and build on land beyond that you inherited in Ikaanos City. Two plots suitable for development are for sale near your home base in Redhaven. Their locations are shown on the map here (to the west and to the south-south-west of your compound). Each is being offered for $40,000. Each has room for a Workshop or a Tavern or maybe one day a Stronghold to be built on it.
