In my very first game with this mod, using the second to last scenario, Robb Stark's rebellion was crushed within the first few months, the Young Wolf captured and executed. Joffrey didn't have long to celebrate this victory though, as a hostile fleet sailed up to King's Landing. Balon Greyjoy killed the young king and sat on the Iron Throne. Then he caught pneumonia and died.
Over the next several years, Theon Greyjoy, King of the Seven Kingdoms by the Grace of the Drowned God, had to fight off just about every other family in the realm - including the Targaryens in the face of the self-proclaimed Aegon VI, but not including the Starks, whose defeat left the North in utter anarchy and disarray. And he won. Time and again it seemed like the Laughing Kraken's luck was about to run out, but his deft strategic maneuvers and political brilliance (he trashed the Tyrells while Lannisters and the Young Griff were tearing away at the Crownlands, but made peace with Mace instead of killing him and so had the remaining Tyrell forces stab the Lannisters in the back while he wheeled around to deal with Aegon - to give just one example) allowed him to defeat all comers and hold the throne for decades, before the return of Daenerys Targaryen and her dragons finally destroyed him for good.
As a bonus, this was before I read the books or watched the show; the mod inspired me to do that. It was more of a WTF moment for every fan of the series I shared this story with than for myself. I must say I was rather disappointed by the canonical Theon Greyjoy and his accomplishments when I got to them.
