Political Setting Overview
The overall idea is to have a stable world where the kingdoms are generally stable and at peace with one another. It's not a "warring states" period where all the states are vying for final domination.
If there is conflict it comes from specific situations.
The reason why I want this to be the case is to setup the main character as a villain who disrupts the peace, not have the MC be a hero who saves the lands from turmoil.
The international system doesn't really have a rule against war, however war is seen as something that is very hard to justify and get casus belli for.
