This is it, the one fact that clarifies so many things. Though it does raise one question: if there isn't any mass or corporeal form, what exactly is their "homeworld"? Brandon mentioned it overlaps with Shear in the multiverse, so what exactly is it if it isn't a planet?
My (not quite biggest, but highest priority) question: In this story you mentioned a bunch of new monsters like the Harrower, Howler, Stormbringer, whatever-the-machine-monster-would-be-called. Could you please give us a list of names for other monster breeds? No details required, just a list of names for monsters we'll never get to see.
