Add a new Dynastic Rule called “Demand and Contentment” with the following text:

Each Monster Species has Desires, a list of Resources, defaulting to empty. Desires are non-transferrable.

If a Monster Species has an empty list of Desires, the Demon King may set its Desires to any valid value. As an atomic weekly action, the Demon King may modify any number of different Monster Species’ Desires by adding and/or removing one Resource each, and make a Story Post with “Weekly Demands” in its subject listing all such changes.

An individual Migrant has the same Desires as its Monster Species.

The Total Demand for a Resource in a given location is the sum, over each Monster Species, of the number of that Resource in its Desires multiplied by the number of Migrants with that Monster Species in that location. If the Total Demand for any Resource in a location exceeds the amount of that Resource in that location, all Migrants in that location whose Desires include that Resource are Discontent.

For the purpose of the previous paragraph, the entirety of a Keep constitutes a single location regardless of how the Keep is subdivided, and all Resources besides Migrants in a Baron’s personal Stockpile are also considered to be in his Keep.

All Unsettled Migrants are Discontent.

All Migrants who are not explicitly Discontent are Content.

Add a subrule to “Demand and Contentment” called “Fair Weekly Demands Guidelines” with the following text”:

All random events in this rule should be secretly random.
When adding resources while compiling Weekly Demands, the Demon King should first choose which resources to add to lists, then randomly choose which species to add them to, with the exception that species with empty lists and species with more Desires than any other are exempt from this shuffle.
When removing resources while compiling Weekly Demands, the Demon King should randomly choose which species to remove a resource from and then randomly choose which resource to remove, with the exception that species with one or fewer Desires are exempt.
When a new type of resource is created that makes sense to be a Desire, the Demon King should add it to at least two lists during the next Weekly Demands.
