In what ways does Schoren communicate with others? Is there a kind of sign language or other means? He doesn't seem to contribute much to their conversations in chapter 9, and even then it's with his eyes/face/body language only so I'm curious now.
Schoren relies primarily on body language to communicate and uses no form of sign language beyond basic symbols most of us would be able to understand.
With the alliance he cares more about observing his peers and how they move through their lives than effecting politics. His country is very secure and secluded and, unlike many others, has moved with a natural pace and rhythm for many years, so there's not much need for him to direct actions like Godwin has to.
It's not that he doesn't want to be involved in politics, it's that Schoren feels the presence of fate in a way that is stronger and more real than anyone else realizes. He believes very strongly that the world has a path that it is meant to follow, and in that way he thinks things will take a natural course and his actions will have little effect in any ultimate outcome.
