Could the "Slave Market" be made into an object on the map? (and ideally, one that can be captured, like a Thief's Den. That is, so that it becomes part of your kingdom.)
*If yes, then a similar question applies to Guilds of Mages, Crystal Columns, and similar Faction buildings.
*I continue to search for implemented ideas to improve and expand the possibilities of the Map Constructor – an integral part of the mod.
