content: The '''Valyrian languages''' are a fictional language family in the ''A Song of Ice and Fire'' series of fantasy novels by George R. R. Martin, and in their television adaptation ''Game of Thrones''.
  In the novels, High Valyrian and its descendant languages are often mentioned but not developed beyond a few words. For the TV series, linguist David J. Peterson created the High Valyrian language, as well as the derivative languages Astapori and Meereenese Valyrian, based on the fragments given in the novels. Valyrian and Dothraki have been described as "the most convincing fictional tongues since Elvish".
