The Chorae are actually sorcerous artifacts (of something called the 'Aporos'), manufactured prior to the Cuno-Inchoroi Wars (by Quya defectors) as a way for the Inchoroi to counter the sorcery of the Nonmen. The script inscribed across each embodies a contradiction that unravels the semantics of all known Cants - even those of the Aporos!

My original idea was for the Aporos to be a 'dead and ancient' branch of the esoterics. I'm still leaning in that direction, but I find the notion of a sorcery based on a semantics of contradiction and paradox almost too juicy to resist!

I may be recalling incorrectly but I thought the Aporos was banned before the production of Chorae. The Chorae being made by the defected Nonman Quya who studied the Aporos inside the Ark under the Consult.

Anyone else clarify?

I think you have it right SR.  The Quya that went over to the consult manufactured Chorae after the Nonmen under CC took them to task...
