Enderal: The Shards of Order is a total conversion mod of Bethesda Softworks' The Elder Scrolls V: Skyrim developed by SureAI as a sequel to Nehrim: At Fate's Edge.
Upon reaching Ark, it is revealed that the Red Madness heralds the approach of the Cleansing, the final stage in a cycle of apocalyptic destruction and rebirth that has occurred for countless millennia, each time causing the total disappearance of the dominant civilization on Vyn.
This cycle, perpetuated across the ages by unseen, shadowy beings known as the High Ones, has recently begun anew following the death of the Light-Born, the ruling caste of mages that were worshipped as gods by the inhabitants of the world before they were overthrown.
The Order's leader, Grandmaster Tealor Arantheal, instructs the Prophet to uncover the secrets of the Pyreans, the previous dominant civilization on Vyn, who knew of the coming apocalypse and unsuccessfully attempted to avert it.
Using old Pyrean schematics, the Order begins constructing the Beacon, a magical machine that supposedly offers the power to permanently banish the High Ones and stop the cycle for good.
As the Nehrimese armies launch a surprise assault on Ark, the Prophet journeys deep underground to the ruins of the former Pyrean capital city to find the Numinos, the 'essence' of a High One, in order for the Beacon to properly identify its target.
The veiled woman once again intervenes in events, and the Prophet is taken to meet the Black Guardian, a human from an unnamed prior civilization that fell to the Cleansing, who attempted to escape it by merging himself into a machine.
The Prophet further learns that they are 'Fleshless', an artificial recreation of a dead person given life by the High Ones to do their bidding, and that their original self died on the voyage to Enderal, when they were thrown overboard into the sea.
One choice is to flee to an ancient city in the clouds to avoid the Cleansing, but leaving the rest of humanity to die, in the hopes that with the proper guidance, the next civilization in the cycle would not fall prey to the High Ones' manipulations.
