Vow of Skirmishes

Political event

The three kingdoms having had many ages of war, enter a vow to only fight in small skirmishes from now on.

Having fought on and off in huge climactic battles and losing more people than any disease in their recorded histories, the Kings of all three kingdoms decide to stop all hostilities and restrict themselves in the future only to do battles based on pre-determined rules so they would not all be destroyed in the next war with each other.
