I don't think the word "demon", or even "Dæmon", appears in The Satan Pit. I'm not 100% if "evil" is either, but the description of the Kaled god of war and Earth, Dæmos and Draconia's "horned beasts" in Pit absolutely doesn't use any variant of "evil creature" or "evil god". Are devils and fallen angels even considered "gods"? They're almost certainly not in real-world Judeo-Christian religions. The Dæmons uses the term "demon" but barely and in no depth beyond the context of the Dæmos species of Dæmons.
