Thinking on 2E take from Dark Eras marks second cult to be filled with Persian and Indian mages, so I doubt it would started as from Aristotel School cult. But my knowledge of Kaprani related tradition is very low and I do not have who and where could start Pancrypties cult as extreme gnostics from those kingdoms. 
I suppose that great influence would be Zoroastrianism, with it's duality on virtuous Ahura Mazda and chaotic Angra Mainyu. I believe that Pancrypties as Darshana cult would equal Angra Mainyu with Fallen World and that 'chaos' want to devour ‘Supernal’ world, and they need to get there, to Ahura Mazda, in flesh ( or so to speak ).
But when I read more on this religion on Wikipedia, I come to realization there are very interesting threads that can be used for Pancrypties background. Here are some excerpts from article:
Maybe a Panscryptia cult could start at Magi revolt in 522 BCE, when mages understood they must defend their lore and secrets from Sleepers influences? Or when in 550 the sow dissent in society - it seams as thing Pancryptias forefathers would do. It also would give nice headway of 2 centuries for the Order from Keepers in spreading in Hellenistic world.
Linked map in article also made very possible to Panscrypties joining with similar cults in India, as Persian Empire was so close to it.
This event would also mark start of nice Pancrypties and Keepers of Word feud, if first where related to Zoroastrianism cults and second would Alexanders successors from Library of Alexandria. Keepers could replay that was their fathers doing, not their, but for Pancrypties it would only point their foolishness in believing that Sleepers will not turn against them.
