Inspired by the game of thrones series, King's Landing is the capital of the Seven Kingdoms, located on the east coast of Westeros, overlooking Blackwater Bay. It is the site of the Iron Throne and the Red Keep, the seat of the King. Aegon first set foot on Westeros in the area of King's Landing at the start of his War of Conquest. On the highest of the three hills of the area, named Aegon's Hill, he built his first fort of earth and wood.
