Formable Nations
Formable nations are special nations that do not exist in the 2275 starting date or Scenarios, but can be formed through a decision or focus enacted by certain nations provided they fulfill the needed requirements.
They act as cosmetic tags and change the name, flag and map color of the nation, but not other aspects like national focuses or advisors. Many formable nations do, however, grant cores on territory, which are otherwise unavailable, and thus allow a nation to increase its manpower and industrial capacity, in some cases decisively, though more practically, many of these merely represent ultimate end goals for ambitious players. There are a total of 21 formable nations by decision, with several others being formed within focus trees or events.
Background
In the array of nations present in Old World Blues, many can complete a variety of tasks in order to form an all new nation. Sometimes, different nations can become the same formable. However, only one of these nations can become the formable. Becoming a formable will almost entirely guarantee a much stronger nation than the one present before it. Buffs included in becoming a formable include more resources, coring of states, and new nation ideas. While being mostly a late game occurrence, some formables can be created by players early on if done right.

The Synthesium Fields
One must play as The Flawed Parish and take the decision "Unite the Plaguelands" which requires owning all core territories of the Plaguelands (except for Glow's Cradle and Crow Creek), and the ruling party must be Ruler. It is important to note the decision will not appear unless the ruling party is Elites or Ruler.
