  ==Background==
  Following an early 2017 leak that revealed plans for the novella to be included in the anthology ''The Book of Swords'' (edited by Martin's longtime friend Gardner Dozois), Martin himself confirmed that the anthology was scheduled to be released on October 10, 2017, and confirmed that ''The Sons of the Dragon'' would be included.
  The story was derived from previously written lengthier material that Martin had prepared for the companion book ''The World of Ice & Fire'', but was removed because the book was becoming too long for the original concept of a fully illustrated book. It and several other stories appeared in abridged versions in other anthologies. 
  The story is included in full in ''Fire & Blood''.
