The trait will occur during a Chaos Invasion in The Old World and Mortal Empires campaigns. Shield of Civilization gives certain factions a big diplomatic boost towards each other, making them more likely to cooperate with each other against the threat of a Chaos Invasion. Factions put aside petty squabbling over land and resources, to fight for the greater good against Chaos. This makes it very easy for the player to create military alliances. Once the Chaos Invasion has ended, the trait will disappear, and the factions will resume their petty wars.
In the An Eye For An Eye campaign, certain factions begin with this trait.
