  ===Novellas===
  Martin has written several prequel novellas. The ''Tales of Dunk and Egg'' series, three novellas set 90 years before the events of the novel series, feature the adventures of Ser Duncan the Tall and his squire "Egg", who later became King Aegon V Targaryen. The stories have no direct connection to the plot of ''A Song of Ice and Fire'', although both characters are mentioned in ''A Storm of Swords'' and ''A Feast For Crows'', respectively. The first installment, ''The Hedge Knight'', was published in the 1998 anthology ''Legends''. ''The Sworn Sword'' followed in 2003, published in ''Legends II''. Both were later adapted into graphic novels. The third novella, ''The Mystery Knight'', was first published in the 2010 anthology ''Warriors'' and in 2017 it was adapted as a graphic novel, as well. In 2015, the first three novellas were published as one illustrated collection, ''A Knight of the Seven Kingdoms''.
  The novella ''The Princess and the Queen or, the Blacks and the Greens'' appeared in Tor Books's 2013 anthology ''Dangerous Women'' and explains some of the Targaryen backstory two centuries before the events of the novels. ''The Rogue Prince, or, the King's Brother'', published in the 2014 anthology ''Rogues'', is itself a prequel to the events of ''The Princess and the Queen''. The novella ''The Sons of the Dragon'', published in the 2017 anthology ''The Book of Swords'', is the story of Aegon the Conqueror's two sons Aenys I and Maegor I "The Cruel". All three of these stories were incorporated as parts of ''Fire and Blood,'' a book chronicling the history of the Targaryen line.
  Chapter sets from the novels were also compiled into three novellas that were released between 1996 and 2003 by ''Asimov's Science Fiction'' and ''Dragon'':
  * ''Blood of the Dragon'' (July 1996), taken from the Daenerys chapters in ''A Game of Thrones''
  * ''Path of the Dragon'' (December 2000), taken from the Daenerys chapters in ''A Storm of Swords''
  * ''Arms of the Kraken'' (March 2003), based on the Iron Islands chapters from ''A Feast for Crows''
