Hi there! First time poster long time reader blah blah that stuff.
So I've read everything and I would like to add my two cents. I've noticed the burned hand has been constantly attributed to Cindy and I personally think a far more obvious interpretation would be fire from Hell itself. We saw last year that A&D atleast acknowledged the Underworld in Hades, so I think hell could easily be recognized aswell. Also I frequently see plays, film, and books that show the Devil as somewhat of a gambler, but I digress.
As far as houses having a connection, I think it's very plausible. I think to have them all connected to a casino would be hard, but if you take what a casino stands for and deconstruct it you have plenty of vague themes that can be incorporacted into a house (perfectly demonstrated with the rumored house names).
I especially love Dr. Jimmy's (huge megas fan btw) connection to the fates and would love to see it happen, though I think they would be less the icon and part of a house that encompasses the casino theme. Especially since we have Three Fates costumes from Hades (if I remeber correctly), I would be surprised if they didnt make an appearance.
So now that I've nitpicked little details I wanted to add to I just wanna say my thoughts on what I see the Icon as being. I think The House could maybe be like some sort of clan, where its members are Fate, Chance, Odds etc. wether they are the supernatural forces they take their names from or if they're just a bunch of lunatics who parade themselves as gods or whathave you. If they are the supernatural forces I think the Gambling your life away idea really sticks, where the psychopath thing is a bit more obvious, lose the gamble and they kill you for funsies.
Finally (sorry for the exceedingly long post) I think the prohibition theme could be used really well, as the backround of that series of laws was steeped in religious dogma. If you have all these people saying drink and gambling and so forth are all gateways to hell and then you have this casino that is a channel for hell itself then I think A&D could really work with that.
Also I think a character like The Dealer would be a great face for the general public.
Anyway...thats what I got out of it. Thanks if you read the whole thing lol(:
