AGE of HEROESGuide
The Age of Heroes is an epoch in the history of Westeros. It began approximately 10,000 years ago with the sealing of the Pact, which brought about peace between the First Men and the Children of the Forest at the end of the preceding era, known as the Dawn Age. The Age of Heroes lasted for about four millennia, from the signing of the Pact until the Andal Invasion 6,000 years ago. This age is so-named for the great heroes who were said to live at this time and perform immense deeds. Some of these heroes were ancestors and founders of later noble Houses and institutions. The history of the Age of Heroes is primarily remembered through myths and songs and weren't originally canonized in books. The most notable historical event of this age was the Long Night and the subsequent war against the White Walkers, which occurred about 8,000 years ago. During the Age of Heroes, Westeros was divided in seven major regions/kingdoms. Although their names roughly correspond with what would later become the official Seven Kingdoms, their actual territory was likely quite different.
