Undercommon

Undercommon is a strange language, having seemingly appeared out of nowhere. For unknown reasons, it is spoken by those creatures that roam the depths of the world. Even completely unrelated species on different ends of the world still speak a mutually-intelligible version of the language. Although it is a simple language, not useful for expressing meaning beyond basic concepts, the fact that it is so widely known makes it useful.
