What is A Knight of the Seven Kingdoms?
The series is a compelling tale set a full century before the political machinations and wars of the Game of Thrones era. The narrative follows two improbable heroes, the young, courageous, but naïve knight, Ser Duncan the Tall, and his diminutive squire, Egg, as they wander the continent of Westeros.
This historical period finds the formidable Targaryen line still firmly holding the Iron Throne, and the last of the dragons remains a vivid, recent memory. Great destinies, encounters with powerful foes, and dangerous exploits await the unique and inseparable friends. The drama is expected to blend epic fantasy with a more focused, character-driven narrative.
