"The gods could not devise a more perfect tongue. It is the only proper language for poetry." ― Missandei
High Valyrian is the language of the old Valyrian Freehold which was located on the eastern continent of Essos. Much of Essos was once dominated by the Valyrians for thousands of years, stretching from the Free Cities in the west, to Slaver's Bay in the east. The Valyrians forced the peoples they subjugated to speak in (or at least be able to converse in) their language.
After the Doom of Valyria 400 years before the War of the Five Kings, "High Valyrian" (as it became known) ceased to be a living language, instead being used as a lore-language by scholars throughout both Essos and Westeros.
But that will change with you!
