The Age of Ist

The Age of Ist, or, The Age of Dust, is the oldest known era of the universe. This period is considered prehistoric and pre-ancient, or even "pre-time." At this time, the universe was roamed by creatures, insects, and fungal organisms who rose and fell in power, intelligence, and development. No human-like races had not yet developed. Exactly how many millenia this age lasted is unknown.
The first known civilization of the universe, the Arachhian Empire, was the predominant power of this age.
