The holy site will be attacked by an army of southerners. Before the attack you will have a choice between building palisades for defense, scouring the grounds for some items or recruit some poorly equipped zealots to help you in the fight.
30% chance: You will have an option to sally forth and ambush the enemy forces. If you choose to do so, you will fight two weaker waves of southern forces one after another.
30% chance: Allied noble forces will offer support. You can either ask them to flank gunners火铳手 or infantry to reduce their respective numbers or order noble forces to stay with you.
