Vratix (language)

Vratix was the native language of the Vratix species from Thyferra. It was high-pitched and used clicking sounds and even skin color changes for punctuation. Species physically unabe to change color and click could understand Vratix language, but not speak it (That covers protocol droids too).

However, Vratix were a social species, trading with many other species. Thus, most Vratix were fluent in both Vratix and Basic, being literate in both languages.
