- The events depicted in The Hedge Knight take place in 209 AC.
209 AC was a spring year. In that year was the death of Prince Baelor Targaryen, the Hand of the King, during a tourney at Ashford. Later that year the Great Spring Sickness began, which killed tens of thousands, including Baelor's father King Daeron II Targaryen, as well as Baelor's two sons and King Daeron's direct heirs, Prince Valarr Targaryen and Prince Matarys Targaryen. Daeron's second son, Prince Aerys Targaryen, was crowned as King Aerys I Targaryen because of these deaths.
