The Aith Elthrenyn, known by mortals as the Gods’ Tongue, is the divine
language of the Domains. Created by Language
in the first hours of the Age of Creation, it is the model
of all tongues born since. It is strongly gendered, symmetrical, sonorous, and
always regular. When spoken aloud its syllables possess the power to command
the Domains, thereby altering reality itself: so long as
the wielder possesses sufficient strength of will, his speech will come true.
Through this magic the Aith is the first and most dangerous of all sorceries.
As a language, it is spoken in secret by the gods, lest its power be stolen by
the mortal races. Yet humans have learned some of its words over eons, and
sorcerers guard its knowledge jealously.
