- "Legend has it that Harlon the Hunter and Herndon of the Horn, two sons of Garth the Greenhand, raised the castle in the Age of Heroes, and shared a home and wife for a hundred years."
- ―Randyll Tarly
Herndon was the son of Garth Gardener and brother of Harlon the Hunter. He lived during the Age of Heroes. Along with his brother, he raised the castle of Horn Hill. There he shared the castle and a wife with him. This way of life went on for them for a hundred years, until one of the two died.
In the books
In the A Song of Ice and Fire novels, Herndon's story is the same. It was said that the wife he shared with Harlon was a beautiful woods witch and that they would not age as long as they had sex with her when there was a full moon.
