Of The Tothic Tongues

Teos, as he was called now, had pondered long on the speech of his people. When he had first come into the world, he learned quickly the tongues of peoples he and his brother, now called Thunar, had encountered, but amongst themselves, they spoke the language that he had devised in the long ages they had dwelled among the stars.
After they had ceased their wanderings about the world they found themselves in, they gathered to themselves a variety of folks who spoke many different tongues to dwell in the vast steppes in the center of Ausalon where the great accord among the Ryuujin had set aside to remain empty.
Teos had instructed his people in the old tongue, but they did not take to it and rather made it their own. Each successive generation saw another set of features disappear. By the seventh generation, the speech was greatly simplified. Gone were many of the most expressive features, and sounds that were once distinct were long merged. The noun case system, conjugation of verbs, and even the expression of number and gender were lost.
And yet, Teos reveled in the changes and took to documenting them as he could, but by the end of the First Age, the new tongue had also began to splinter as his people had grown numerous and were separated by the many encircling mountains of the Great Steppe.
