The Empire spanned the width and some thousand miles north to south. They existed along with other peoples (e.g. Est E’ Kiapan) in what was a time of human dominance on the continent.
Then some ten thousand years the empire began to fade away. The exact causes of the empires failures are lost in time. It is known that the hordes from the north and other locations began to rise up and the wilderness expanded to encompass the empire’s lands. Until the final Kingdom of Gl Gliraca was lost some 1700 years ago.
