Going to war is Sahi's. Agreeing to marriage is Aalam's. I do not know of any guides myself, but I hope you saw Harlevin's comment to yours about doing some gentle choices because that's the ruling style you need for his. So I guess, witty and gentle are probably the main things for his route? I haven't played in a while. I may have to go back and experiment and write down every choice I make and what endings I get.
