The following is a synopsis of a segment of The Chronicles, a book of history compiled by Varassed, the Chronicler to Shah Yamin IV (compiled around F.D. 2500).*
In all the legends and lore that surround the origins of Haranshar, none occupy as privileged a place as the Old Ones, according to legends the first humans who were able to build a civilization on the vast continent of Aridikh. Though their origins are in truth unknown, the priests of Ormazdh and the other tenders of knowledge have taken to calling them the Old Ones. The oldest records state that they came from across the Eastern Sea, from the fabled Middle Kingdom.
Regardless of from whence they came, the Old Ones soon conquered the various tribes that had been living on Aridikh, bringing them under the rule of what would become known as the Hegemony. From Hamarkhan in the furthest west of the continent to what would become Aspaña in the west, the Old Ones ruled supreme, their many powerful lords, kings, and princes existing in peace and harmony with one another.
Under the Old Ones, the world was reportedly full of technological achievements the like of which had never been seen before and which have not been matched since. They were able to make the arid lands of the western parts of Haranshar blood, reputedly even forming the great rivers that would nestle the most fertile lands in the world between them. They planted seeds and cities alike, and there were rumours that the greatest among them, the Shahs (of which there were reportedly 30) could communicate with one another across vast distances. Their courts and cities were full of singers and craftsmen, priests and sorcerers, beautiful women and men and others who were neither or both, and all lived in harmony.
Their faith was one based on a celebration of the material world and all of the pleasures that it offered. The world was divinely ordered, so their priest said, and there was nothing to be gained and everything to be lost by looking beyond it. There was in this theology no concept of an afterlife or a spiritual realm, which may in part explain the events that would soon bring this halcyon world crumbling into ruin.
For, as with all pinnacles, it was only a matter of time before the Old Ones fell prey to the desires of each other to conquer the others. They started the Great War, in which each mighty house was turned against its neighbour, and each and every one thought that it had been given the sole right to rule unchallenged all over the continent. The Shahs declared war one upon the other, even as their own lords and vassals declared war on them in turn. Rebellions and revolutions erupted in every province and kingdom, and even the common folk rose up, led by a series of wandering priests who declared the ways of the Old Ones to be hopelessly corrupt. The world, they said, needed to be purged by flame, and in this rebellion was sown the seeds of the faith that would eventually become known as Ormazdhism, though at this early stage it was merely part of the fires of chaos.
The conflagration soon spread out of all control, and the great civilization that the Old Ones had built collapsed into utter oblivion. Their wars raged across the entire continent. Civilization began to collapse into barbarism and cruelty, as neighbour was turned against neighbour and even families were torn asunder as their loyalties switched between various sides of the conflict.
There are no accurate records of what happened after the great culture of the Old Ones collapsed into anarchy and barbarism, for the great libraries that they had built to preserve their knowledge for the future were one of the first casualties. There is much that even now, with all that we have managed to achieve, that we do not understand about how they build their world and how they were able to stay in power for so long. All that is known is that there are still great towers and ruins scattered across Haranshar and the Imperium, testaments to their achievements. And we have a few tattered parchments and the legends of the singers that emerged after the Fall, when the world at last began to knit itself back together.
There was no recapturing the past glories of the Old Ones, however, and there were none of the great Shahs left after the collapse of their hegemony. It would be many centuries before the people of Aridikh began to pull themselves back together, and it would take one who claimed to be of the proud blood of the Old Ones (though the veracity of that claim was disputed then and is still questioned) to finally reunite them all. He would be the one who was known as Kharyush, the first of the Shahs whose reign over Haranshar (including the domains that would later become the Imperium) was complete.
Most provocatively for the present, however, there is a belief among the Korrayin, handed down from these dark days, that it was at the Pillar of Creation, the great mountain that stands at the center of Korray, that the Old Ones first came to be enlightened. The Pillar is said to be riddled with caverns and secret parts that no man has fully explored,
Furthermore, it is believed by some among the Alchemists that it was the Old Ones who first perfected the Art of Binding, and that it was through their use of the Bound spirits that they were able to bring about the great culture that was their accomplishment, and there are some among the priests of Ormazdh that believe that through recapturing that technology those who live in the present can regain their past glories. That, however, remains to be seen.
*The Haransharin follow a different dating system from their counterparts in the West. They date everything from F.D., which is short for First Dynasty, after the original dynasty to rise after the fall of the Old Ones.
