Hank, the tiers are rather broad I grant you - but they had to be as we only have a few distinct cosmic power levels in the Dresdenverse (Creator, Archangel/Major God, Minor God etc). I am not sure what you mean about the Creator gods not being peers to each other or a monotheistic deity...at different times in history, ancient mythologies were the dominant religion of certain regions. I will grant you there has never been the scale of worship to the Abrahamic God, but that is a factor of population growth more than increased levels of worship (indeed, religious belief is shrinking in most parts of the world).
Exartiem, I wasn't really arguing that Hecate was only the three Queens of Unseelie. She was likely a being that was three parts, then split again and became six parts (Summer and Winter). Why she had to split into Summer and Winter is unknown, but I wonder if it was because the fae were already seasonal based, and in order to become a part of them that was required?
I do agree that it is no mere coincidence that Nemesis (the Outsider, the Adversary) shares the name as another minor greek goddess, when Hecate seems to be the ruler of fae. Maybe she was the first infected. Maybe Nemesis and Hecate were powerful Witches who ruled like gods in Atlantis, a la Hellboy. Maybe it will be like the Chronciles of Amber and there is a Prime/Base reality that all the powerful gods etc come from, which is where Hecate and Nemesis come from except Hecate joined the DV version of the Courts of Chaos.
I certainly expect Jim to pull a fast one on us.
