Language Creation for A Game of Thrones

Over at Geekdad, they've posted an interview with David Peterson, who has been charged with creating a new language specifically for the HBO adaptation of George R.R. Martin's A Game of Thrones.  I look forward to watching this eventually, as I don't subscribe to HBO.  I enjoyed the first three books of Martin's series immensely.  I didn't get through my first effort on the fourth book of the series - the main problem was the span of time between the third and fourth books, which was so long I had trouble picking up where the story had left off.  I'll probably go through the whole series again from the beginning at some point, especially now that I see this production being made.  HBO tends to do this sort of thing well, so hopefully the screen version won't disappoint.  The interview is worth a quick read; the linguistics of creating a new language based on a fictional world is interesting (at least to me!).
