Robert of the House Stark, the Second of his Name, King of the Andals and the Rhoynar and the First Men, Lord of the Seven Kingdoms and Protector of the Realm.
There was quite a bit that needed to be done. Firstly, of course, was a personal consideration. King's Landing was a ruined heap of ash and corpses. Stannis had planned to make Storm's End into a temporary capital for the years it would take to rebuild the Red Keep, for that was his right as head of House Baratheon.
That title was arguably now held by Selyse Florent, until your betrothed came of age. You could not be sure she would be thrilled to host the man who had dismissed her daughter's claim and taken her husband's army. You frowned. You had done what was necessary to maintain the wartime coalition and protect the realm. Stannis' grandson would one day rule Westeros.
You were also the Heir to Winterfell. It was your home, and you ached to see it again. But a part of you recognized that you might not get to call it home anymore. Perhaps Rickon would one day rule father's lands, or a second son of yours could be fostered with his grandfather.
The ruler of the Seven Kingdoms needed a seat. With that decided, you would be free to move forward with Dorne and the Targaryen pretender.
[] King's Landing will take time to rebuild, but it has served as the heart of the Seven Kingdoms for three centuries. You will move your court there in time, and until then rule Westeros from somewhere else.
[] To hold your court at Dragonstone would place you in the Narrow Sea, distant from your subjects and close to the Free Cities.
[] When you wed Shireen, Storm's End will be yours just as her father's crown has become. It was built by Brandon the Builder, legends say.
[] Your kinswoman already rejected Rickon as her heir, but your claim to Harrenhal is strong and you could take it after her death.
[] Winterfell is your home and you are a Stark. It will be odd sharing the castle with father, but there is no reason you cannot rule from the North.
