I agree, I did borrow some ideas from the four horsemen, but the seasons have always been there, and even sometimes represented in literature as beings (i.e., old man winter). I just figured if the fairies were to be more threatening than before they would also have to have elite members.

Every fiber of me wants to say the Leviathan can't, but their age and the immunity (or negation, whatever) Edgar displayed to the younger angels is that one? road block that keeps me from agreeing with you on archangels vs. leviathans. I would easily discard the belief that Leviathans can suppress powers of archangels if I have canon proof, but seeing as there is none, and the prevalent trend is that age is might (best shown by Eve vs. Castiel) keeps me on the other side of the debate.

The side I choose isn't personal preference, it's just more of lack of canon proof.
