Draconic

The native language spoken by dragons and dragonborn, it was the first language of Valine and, along with Sylvan, heavily influenced the development of the Common Tongue. Draconic is a guttural language, but strangely pleasant on the ear, with long, musical vowels filling the gaps between the harsher consonants produced in the throat. It's written form is beautiful, almost entrancing, and frequently used to record divine spells and the holy books of many religions.
