Supernal

Supernal is the language of the gods. It is a universal language, understandable by any sentient mind (who hear the words as if they were spoken in their own languages). The gods shared their language with their servants, the angels, and devils speak a version of it as well. Mortals are unable to learn the language completely, so the words of creation lack power and they are unable to use Supernal to make themselves understood with those who speak only other languages.

Supernal is written using hieroglyphics.
