No such thing happens at all. In a body that far outstrips human abilities, vocalization is unnecessary. The hundreds of things the body can communicate by the merest movement are astounding.The only thing that can be done is scream (the base unit of existence). And since no one can die or grow older, it is the Eternal Base Unit. The demon could not express itself in an elegant manner, for such things require reflection and ruminating over matters, and no such thing can occur here. It is only my own narrative device. The thoughts are just there, hanging in space like raw wounds - pay attention or not; they will occur as he proclaimed them. Nothing can prevent this torment from one so high on the Order's ladder.
