So now that we know at least one group of Rosharans are aware of the Sleepless (the Horneaters), are there other Rosharans who know of them as well?
By which I mean - have the existence of the Sleepless influenced Irialian religion and the belief in the One?
There have been Iriali who know about the Sleepless, though the Iriali religion predates their arrival on Roshar. (That said, it has evolved during their time here.)
So the idea of the One - a single entity breaking down into smaller, constituent parts in order to gain diverse and varied experiences - predates the Iriali's contact with the Sleepless?
And now that I think more about this theme of a single entity breaking down (splintering/fracturing?) into smaller parts... could the belief in the One and the Many be influenced by the fracturing of Adonalsium? Or is this general theme just a coincidence?
The general theme is not a coincidence, but the Iriali having this philosophy predates me bringing the Sleepless into the Cosmere from another science fiction book I'd written during my early unpublished years.
