I hope you won't have Radnor waste time making friends. if he has to please just have him reduce the Stark army to ash. Sometime, you need to show overwhelming military might to defeat your enemy and just utterly annihilate them. Aegon the Conqueror did not waste time repeatedly giving people chances. He gave them one chance to kneel willingly, then it was dragonfire. so do not have Radnor waste time having dialogue with the North, have him destroy their army and erase House Stark, that will throw them into chaos and the replacement lord will be installed with House Targaryen support.
Yes, this is the way he should respond are you with me are you against me? There is no in between. There is no negotiation. Personally it would be more intelligent to wipe out a lot of houses in Westeros. Once you conquer, slavers bay, there will be some people there that may be able to take a position. First of all, he should’ve been conquering essos before he even came to Westeros. He may have dragons, but he’s coming to them weaker than he should be. His ancestor came with three dragons but also a small army. Person in this is how he should’ve come. He should’ve burnt the storm lines to the ground creating a second field the fire. Then burning the Lannister seat to the ground as well.
