I wouldn't recommend to defeat Aalia first; I'd recommend you beat Bernad first. Everything else is alright. It's just that when you attack Aalia, all the other pretty powerful guys will hurt you, so you spend a round healing + curing ailments, and while you do that, Vennie and Aalia heal Aalia and Bernad and Bartholio attack you. And Vehrn can take Bernad out in one or two rounds. So... yeah.
