A brilliant, logical thinking species can only express that brilliance if their language supports it. The Anu language is a highly structured language that allows for the expression of complex ideas with a great sense of integrity and personal power.
It is a language of power that is tied closely to the respectful nature of Anu culture. Lying in this language is impossible, and speaking mind to mind is easy.
Today, if you advance far enough into the program, you can learn a little bit of this language through the Elfpath institute for intuitive development.
