Three novellas have been published – The Hedge Knight (1998), The Sworn Sword (2003), and The Mystery Knight (2010) – and Martin has stated his intention to continue the series. The first novella was originally published August 25, 1998 in the Legends anthology, edited by Robert Silverberg. The story was later adapted into a six-issue comic book limited series by Ben Avery.
