David J. Peterson is an American conlanger who has constructed languages including Valyrian (High Valyrian, Astapori Valyrian, Meereenese Valyrian) and Dothraki. This will include dragon command, simple phrases and glyphs. Much of this is taken from David J. Peterson's social media, official material, the show itself, and his discord: "The Languages of Ice and Fire Community", I will add links to some.
