The True Speech, known in its own tongue as the Aith Elthrenyn, 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.
