Game concept
Discontent
From the game's encyclopedia
Discontent is a measure of how close a Faction is to issuing an ultimatum.
If a Faction's Military Power is at the threshold, Discontent will increase every month. If Military Power is below the threshold, Discontent will decrease. Very powerful Factions will have their Discontent rise quickly.
