Before this last war it was the Lannisters that ruled, before that Baratheons and before that the Targaryens. Now there are so few of those left and those that are do not wish to rule. So the title of King of the Six Kingdoms fell to Bran, decided by the last of the Great Houses. I probably bore you with details- much has changed in Westeros even over the course of my life time."
