I do like the link you make with the "unspokeness" theme, though. Secrets, the past, godlike authority figures found to be all too human, flawed, even abusive of their power, these are all major themes that occur over and over in Neil's work.

Also, do you have a link with a definition of the 8th Dynamic? What attributes did you see in it connecting it to the Nameless God? It's mentioned in your first link but not really described much... Though given the secretive nature of the church, that might be a bit much to ask. hm, there's that unspokenness again... though I'm not thinking that's enough to make a strong connection.

I just finished re-reading American Gods and while I was reading it I thought the unnamed god was Luck, but the more I think about it, Luck would be female and this was obviously male and I just don't know who he was. It could be the Flying Spaghetti Monster for all I know. Although that'd be a new god though...

I'm thinking it's Hades.

Traditionally, in addition to being god of the Underworld, Hades was also the god of all the earth's treasures as well. Also, Hades was not his actual name.

Hades' actual name was apparently purposefully forgotten by the Greeks who, while they gave him his due as most gods-fearing people do when worshiping, did not want to call his attention and wanted to remain clear from his realm for a while. It was considered really bad-luck to utter Hades' true name, if he actually had one.

This might have already been mentioned here or in some of the other threads -- but I think our unknown rich gentleman is the American equivalent of the Greek god of the Underworld: his hands in unseen (and probably in some cases illegal) riches and gambling enterprises, and his face always unseen -- from a resonance of over a thousand years of attempting to obscure him out of fear.

My guess is GAD - a semitic god of fortune who appears in Isaiah 65:11 whith the goddess of fate/fortune, Meni.
