This seems as good a place as any to ask a question that's been bugging me for awhile.

Okay Westeros, is called the Seven Kingdoms because of the seven kingdoms that Aegon the Conqueror conquered. I get that. Here's my problem, I count eight kingdoms: The North, the Riverlands, the Vale, the Westerlands, the Reach, the Stormlands, Dorne, and the Iron Islands. So which of those isn't counted?
