The Primordial Era is the first age of the Aethereal Stories universe — the era before any of the others were possible. It encompasses the existence of Infinity before the events that shaped it, the collision between Aetherius and Pandemonius that forged existence, the rise and fall of Asgard as the first great civilisation, and the descent of primordial beings to Earth at the dawn of human history.
It is the era of the Aethereal Chronicles — the imprint that shelves the books recording these events in The Divine Library. The events of the Primordial Era are the foundation on which every subsequent Era rests. Every force active in the Mortal Era and the Modern Era has its origin here.
