If the description of the gold trimmed robed Schoolman is indeed Saccarees, and if he is a Nilnameshi, doesn't that immediately discredited him as being a bona fide Dunyain? Aren't all Dunyain just by merit of their geography and eugenics breeding all going to be Norsirai. While a Nilnameshi would be a completely different ethnic group. I'm one to support the notion that Saccarees is basically one of Kellhus greatest pupils and has been training and training him. The conclusion being, that even a world-born human through tremendous cognitive discipline, mental focus and zeal can actually grasp the Metagnosis, grasp it, but certainly not master it like the Holy Aspect-Emperor.
