The Terrible Ones

The "Terrible Ones" is the translation of the Seic name Rhashokyn. The name was given to the first civilization that arose on Khos, roughly 200,000 years before FE 1. Their empire spanned all four habitable continents, devouring resources and causing many species to go extinct, and endangering nearly all other intelligent life on Khos. Their empire fell as the Archons were created by Khos, who destroyed their buildings and killed the majority of their people.

Culture
Much is unknown about the Rhashokyn culture, all records of their life and language were destroyed by the Archons. Their true name is even unknown. The Uyagr claim to carry out the old traditions, though there is no way to know for certain how well the culture has been preserved.

Description
According to Uyagr oral history, The Terrible Ones stood twice as tall as their descendants and were ten times as strong. They grew feathers, similarly  to the Uyagr, but they were supposedly larger and more ornate. The Terrible Ones discovered smithing and military tactics thousands of years before any others species on Khos. Human history mentions their impenetrable armor and immense pole-arm weapons.

Legacy
While the Archons dismantled the Terrible Ones' grasp on the world, the residence of the supposedly massive city of Uyag managed to take refuge in the Mt. Trinos region of The Barricade Mountains. These displaced citizens banded together for survival in a newfound tribal system, referring to themselves as the Uyagr. Throughout thousands of years, the Uyagr tribes spanned most of the Ironland region, and thrived there until Humans drove them out circa 150 FE. The Uyagr refer to the Terrible Ones as Gohmhr, or "The Ancestors".
