A quick note: This is a semi canon roleplay however You don't have to play a canon house or characters for that matter however there are limits to what you can do with the history of westeros.
The action begins in the unified Seven Kingdoms of Westeros as the long summer ends and winter draws near. Lord Eddard Stark is asked by his old friend, King Robert Baratheon, to serve as the King's Hand following the death of the previous hand, Eddard's mentor, Jon Arryn. Eddard is reluctant, but receives intelligence suggesting that Jon was murdered. Eddard accepts Robert's offer, planning to use his position and authority to investigate the alleged murder. However it seems that all is not well in Westeros as it seems war is about to start. Lady Catelyn Stark had captured Tyrion Lannister in an attempt to bring a confession out of him. However Tywin Lannister seems to have intentions of taking out House Stark out of indignation for his sons capturing. Ned Stark in King's Landing is also busy finding out what truly happened to Jon Arryn. However after this Canon diverges from the game of thrones. We will be playing as a group of houses gathered under a banner in an attempt to gain the kingdom for ourselves. We will start out at King's Landing a couple of days before the events of the coup attempted by Stark and Renly fleeing from King's Landing. Or we will start out in a castle meeting between friends discussing what to do if Lannisters or Starks come. It will be up to us to unite Westeros against the other five kings Joffery Baratheon, Robb Stark, Stannis, Balon, and Renly. We will forge our own history that will put the Targaryens to shame...
Alright so with that out of the way you get the jest we will be playing as a new kingdom bidding for control of Westeros. You will be playing as the head of a house and the members of a house (We will be splitting house members up so you will be playing one in one place in another somewhere else. when we switch perspectives so to speak basically we will be switching from say an eastern campaign to a southern campaign). You will be able to play multiple characters. You will also be able to rename your house and even change canon of their history. Of course you shall also be allowed to play as player made characters as well. However there will be a set of houses not allowed.
Houses: Tagaryen (If you want to be a branch house that survived pm me and we'll talk), Tully, Stark, Baratheon, Night's Watch, and Lannister are out of the picture for story reasons. This means they are unplayable not that they are missing. I will play as the King of our country (because if the person who is playing king leaves there is not a giant gaping hole in the roleplay) leaving you to battle, play politics, and fight to your hearts content. If you have any other ideas I'm open to suggestions. Of course I will be altering canon to fit it. Like replacing Robert and Lysa as Jon's Arryn wife and son, Walder Frey dying earlier etc.
