Ostensibly one kingdom, Westeros falls into chaos over what started as a grudge between two houses. The War of the Five Kings illustrates how quickly opposing factions can come into direct conflict when they see opportunities to secure their interests. Each of these factions fight for a different motive. Meanwhile, two more great houses try to declare independence from the Iron Throne altogether. Two brothers fight over succession with their nephew, King Joffrey, as well as each other. In the second season of Game of Thrones, a disputed succession quickly spirals out of control and initiates The War of the Five Kings. If two families vie for the throne, only one can achieve their goal. Most obviously, this occurs when interests are mutually exclusive. Factions form because the motives within a group are not unified. Now to build that interest, follow these three steps for creating factions.
