Oh no not to take away form your work either man. I couldn't even fathom all the symbols and what not.
I do see each little symbol equating to an icon. Reason the whole carnival of madness quote just scream Jack to me... and it would make sense. Pehaps as you and others stated that the are liniking the icons to Mythological gods and demigods.
On Another note the little play between TJ and LT is ammusing. It would be a significant plot twist to see that, even if LT has the best interest, perhaps this Fell character does not and... we being the naive, good-intentioned agents... are responsible for the furition... the vehicle of the events about to occur. When, all along, Universal was trying to keep the Lantern under control... we are lead/accidentally blow it wide open for the ultimate evil to come forth.
