The Recent History articles, which in broad strokes summarises the history of the game (as well as VERY briefly touches upon the history preceding the opening of the game), has finally been brought up to date. You can find it under Articles, at http://www.westeros.org/BoD/Articles/Entry/Recent_History
The State of Play in King’s Landing and State of Play in Sunspear articles will soon be updated as well, picking up from where the Recent History leaves off to give a sense of the current status of the game’s two open areas.
