He created the Dothraki and Valyrian languages for HBO's Game of Thrones, and more recently has created languages for the CW's The 100 and MTV's The Shannara Chronicles. His new book, The Art of Language Invention, details how to create a new language from scratch, and goes over some of the specific choices he made in creating the languages for Game of Thrones and Syfy's Defiance. David has agreed to give us some of his time to answer any questions you may have. As usual, ask as many as you'd like, but please, one question per post.
