Quick question. Are devils and demons just under one big classification of fiends in eberron or do they still believe in the 9 hells? Each of the planes uses demons and devils in different ways. In Shavarath, devils embody tyranny while demons are terror; but they have no connection to the demons of, say, Fernia. Exploring Eberron covers it in more depth.
