Change the rule “Keeps” to read:

Each player has a publicly tracked Keep. Each Keep has 8 publicly tracked and ordered slots, each of which may contain up to one Infrastructure. If an Infrastructure’s effect contains the [Defensive] tag, it may only be placed in the first three slots of a Keep.

Add a new subrule of “Keeps” titled “Infrastructure”:

There exist a number of different Infrastructures, each of which has a name (which is flavour text), a list of Resources representing its cost, an effect, an integer number of hit points, a non-negative integer maximum population, and a list of Migrants which occupy the Infrastructure. The length of an Infrastructure’s list of Migrants can never exceed its maximum population. If an Infrastructure’s hit points would ever exceed their default value, they are instead set to their default value. At any time, a Baron may spend all the resources in an Infrastructure’s cost list from their personal Stockpile to Construct it by placing that Infrastructure in any unfilled slot in their Keep. The list of all Infrastructure can be found below:

{| class="wikitable"
|+ Infrastructures
! Name || Cost || Effect || Default Hit Points || Maximum Population
|-
| House || Wood (chopped) x 4, Stone (cut) x 2 || None. || 100 || 4
|-
| Wall || Stone (cut) x 3, Iron (plate) x 5 || [Defensive] || 400 || 0
|}

If the Proposal “Only Somewhat Present” passed, add the following Infrastructure:

| Mine || Wood (log) x 5 || When the Baron who owns this Keep gains the Effect of the Exploitation Station, they may roll DICE4; if the result is 1, an additional resource of the same type and subtype is gained. || 200 || 2
| Lumbermill || Stone (cut) x 4, Iron (bar) x 1 || When the Baron who owns this Keep gains the Effect of the Deforestation Station, they may roll DICE4; if the result is 1, an additional Wood is gained. || 200 || 1
