Age of Heroes
The Age of Heroes, an era during the history of Westeros which takes its name from the great men and women who lived in the years of peace that followed the forging of the Pact, to which many noble houses trace their family histories and many stories, Songs, and legends are told about.  It is an era that is shrouded in mystery, with more myth than fact known about it.
The Age of Heroes began with the signing of the Pact of the Isle of Faces. The Pact ended the War of the First Men and the Children of the Forest, and lasted for nearly four thousand years.
During that time, a hundred kingdoms rose and fell. This was a rugged time where many ancient traditions and legacies forged by the First Men were established, with influence from the children. Many of these customs live on among the lords of the North, who still bear the blood of the First Men in their veins. The laws of hospitality, the obligation of a judge to also be the executioner, and the renowned Wall are all accredited to these ancestors of the northmen even the barrows of the First Men can still be found throughout the North. This was the time when many legendary kings and heroes walked the earth, such as:
- Bran the Builder  - who built the Wall andWinterfell. He is accredited for other famous constructions, especially Storm's End.
- Lann the Clever  - who supposedly swindled Casterly Rock out from under the Casterlys using nothing but his wits.
- Garth Greenhand- who founded House Gardener of the Reach, and from him sprung numerous other lines and families.
- Durran - first of the Storm Kings, who raised Storm's End to check the wrath of the gods for wedding their daughter Elenei
- The Grey King  of the Iron Islands - legends hold that he wed a mermaid and became king of the western isles and all the sea beyond.
- Symeon Star-Eyes - a legendary knight who was blind.
While much was achieved during this ancient era, it was at a cost - in the midst of the Age of Heroes fell the longest and blackest of winters - the the Long Night which heralded the arrival of the Others.
The oldest histories we have were written after the Andals came to Westeros. The First Men only left us runes on rocks, so everything we know about the Age of Heroes and the Dawn Age and the Long Night comes from accounts set down by septons thousands of years later. There are archmaesters at the Citadel who question all of it. Those old histories are full of kings who reigned for a hundred years, and knights riding around a thousand years before there were knights.”
