In the first year of the Dawn Era, Piranoth, a primordial with the powers of Creation began forming worlds out of the energy and matter floating aimlessly about Chaos. Rushing his work, creating too many worlds without planning, fell energies seeped in. One theory is that someone took affront to what he was doing, poisoning the work of one creating order, violating the Primordial Mandate.
Piranoth's first world, the Step of Foundation, seems to have been the root of the corruption that came. With many rifts, this world served as a hub for shuttling energies and matter from Chaos to the vast system of stars and worlds that would become known as Piranoths Steps.
The Hirstyr Signir monolith has writing on it that say over thousands of years, the Step of Foundation absorbed corrupting energy and baleful soul energy. This dark energy sunk to the first world, coalesced, and then reversed course, spreading outward along the rifts like tendrils of corrupting darkness. These tendrils were evil energies that fused with the entropic energies of Chaos, termed by Bruh Kreniik as the Threads of Damnation.
The Threads of Damnation are blamed for the rise of the demons, natives of what is today better known as the Abyss.
