The Broken kingdoms
The war of ice and fire saw the ascension of Brandon Stark as ruler of the seven kingdoms in an unprecedented election by the remaining high lords of westeros , however he soon made his first blunder by immediately granting the North independence at minimal urging from his sister. Though the lords at the council made no issue of it at the time, this already set a precedence that would doom Westeros as a unified continent.
In the meantime however the new king had to deal with issues in the ruined and burnt king's landing , chiefly among those were the septons denouncing their new king as an abomination of dark magic and began stirring trouble. At first gathered little following but as some of the more extreme began to drop dead in mysterious circumstances; people began to be afraid of their new king.
Not helping this was the sheer ineptitude of the new Master of Coin, sir Bronn of the Blackwater who now had the title of lord paramount of the Reach. Why the new king had chosen a common sellsword with no experience in finances and economics to this position baffles historians to this day. The Master of Coin's heavy handed attempts at gaining credit only added to the disgruntlement of the smallfolk against their king and drove many into the arms of the reborn sparrow movement
It should be noted that this was not the only questionable choices King Bran made for his small council like allowing Samwell Tarly to be Grandmaester despite never officially becoming a maester (A fact that drove the order of maesters to oppose his reign ) and making Brienne of Tarth the lord commander of the Kingsguard ; though the lady was certainly most qualified in martial skills , most surviving knights and lords refused to join the kingsguard on account of having to serve under a woman.
The first year of Bran Stark's reign hadn't ended before he faced new problems , Dorne under Quentyn Martell and The Iron Islands under Yara Greyjoy declared their independence from the Iron Throne.
