Throughout different media across Game of Thrones' many incarnations, High Valyrian is the language of the old Valyrian Freehold, located on the eastern continent of Essos.
In the world of A Song of Ice and Fire, High Valyrian occupies a cultural niche similar to that of Classical Latin in medieval Europe. The novels describe it as no longer being used as a language of everyday communication, but rather as a language of learning and education among the nobility of Essos and Westeros, with much literature and song composed in Valyrian.
(The Valyrian writing system is characterized by being, not dissimilarly to Egyptian, both phonetic and ideographic; utilizing not only glyphs representing individual sounds, but also objects and ideas. These ideographs were coded into this font, and can be accessed vía OpenType features where supported.)
