I know the mc doesn't have any real power yet beyond his personal power, but I'm starting to get annoyed with him following what the Targaryens say without even arguing, I mean he might as well deny the making of valerian swords and keep more about the future for himself, even more with him already bonding with the Targaryens by marriage and dragonstone, it gives the impression that the MC will only end up like House Velaryon, which even though he has Valarian blood has to follow the orders of the Crown Targaryen.
great chapter. just a suggestion since he has got dragonstone as his keep he should try and recruit soliders and knights to his service and dragonstone is to small to make his house. Also he should fly to Essos and start searching for valyrian reminints and free some slave families men, women etc since getting more people from westeros will not be a good idea since they all follow the 7 and some guys are agents of old town and the citedal. And he should use the knights he hired to Train those free slaves in to soliders and later he should Truy and get more agricultural land for food security.
