Gotta try to find my copy of Niven/Pournelle's "Inferno" to reread again...
Is there a line similar to that in there?
I had read some of Paradise Lost in Ancient English Lit class, but I am not familiar with Inferno.
But that is how I see them. That is all that comes out of them.
They vomit lies all over everything and everyone all day, every day.
Are they demons? By definition, no. But they serve demons.
