Well, I beat the game, but I'm still trying to finish this quest and "A General's Story". I already found every Diary in the Homestead and talked to Alessa in the chapel.
But the quests are still unfinished and I can't talk to the other inhabitants of the Homestead about my finds.
So, have I overlooked something? Do I have to talk with someone outside the homestead? Or is this quest just unfinishable?
