Sorry, let me rephrase that. It wasn't internal pressure from VE that I felt caused the war, but rather Caerwyn elites using religion as a scare tactic to rile their realm up. They tried to say that Asylon was going to turn into an all SA realm as well when we declared religious freedom among the nobility.
My character was more interested in keeping VE as a religion of meditation, as opposed to a religion where everyone is off to war to guard it form SA.
