It is often forgotten that when the Moirai were founded by Sauja Chan in the years following the Crash it was not for altruism but for protection. Sauja Chan was among the first of humanity to evolve extrasensory abilities, and one of the first to be prosecuted for them. For her, the Moirai was to be a society of outcasts raised to a level of such prominence that they were beyond the persecution they would otherwise face.
But how did she accomplish this? And how did the Moirai keep the secret of the true reason for their existence for millennia?
Moirai doctrine stresses the importance of secrecy. When reading the works of Sauja Chan it is nearly impossible to find a single paragraph that does not emphasize the importance of silence. Consider the young student who joins the Moirai for training that usually lasted an average of six years between Induction and the Rights of The Initiate. By the time they have come for training they know the prejudice that exists towards their abilities and already have found some way to conceal them. Then the next six years spent constantly drilling on the importance of secrecy and the punishment for breaking a Moirai secret. By the time the Rights of the Initiate are taken is it any wonder that few Initiate ever mention their powers even in their own journals?
In the end of course the Moirai Secret was suspected by some. But by then the second part of Sauja Chans plan had come to fruition. The Moirai had made themselves indispensable to the Known Nations. They were the chroniclers, arbitrators, healers, and artisans. Their influence in the world was so great that not even the dogmatic Theocracy of Eurydice ever challenged them in any meaningful way.
It is perhaps ironic now, when extrasensory abilities are widely accepted, that Sauja Chan is forgotten because she kept her secrets so well.
