Well, in my view, certainly it is in the Hierogrammates' look back in which they discover
humanity. Like studying their history, they learn that in their Briatic origins the humans
who arose from Ushas evolved into the Hieros which led to them. History also tells them of a 
folk hero named Severian who made Ushas possible.
 
In this history they learn that the hero, Severian, was advised by beings like Hiero-
dules and judged by Hierogrammates and thus they know that they must send agents back to 
Briah, to interact with Severian and fulfill their history.
 
Sorta like Severian with the primitive people. He knows he has become Apu Punchau, he knows
in teaching them architecture that he is fulfilling a pre-determined role, but he pretty much
just has to play along and do it.
