Each poster is a decision for the character on which castle the want to join. So after they read it they go to the castle they choose and talk to the lord of the castle. He gives you this quest line and sets you up with your squad. The character goes to the Barracks and talks to his squad captain. The go on a mission and blah blah blah ill leave the quest for your self. But anyway when your done with the quest line you become the Lord of the Castle and the enemy Lord is still alive and your castle is destroyed because you lost the war so now you have to rebuild it since you are the Lord now. The player would maybe still want to keep fighting the Enemy Lord and send squads to fight at the war so the enemy Lord doesn't have to die if the player does not wish it.
So back to rebuilding the castle the New Lord has to buy every thing in his castle walls Houses for the peasants and new servants new rooms for your castle and recruiting more men for you army.
So that is my suggestion I hope you make because I thought this was a really good idea.
