Due to the rapidly increasing length of the post that I'd been working on, I've decided to break it up into two parts. I'm about to post an introduction of sorts for Faustus; the part that I collabed with Lauder is being separated and can come later.

Though it's perhaps not my place to answer all of your questions there [@Polybius], regarding number three it's probably worth mentioning that [@The Incredible John] has a religion of sorts among the undead that he detailed in his sheet over on the interest check thread.

Question number four is perhaps the most pertinent to me since Faustus is the character most closely associated with commerce and I'd imagine that I'll be doing most of the heavy lifting for that particular aspect of worldbuilding. You might get some idea as to the answer between reading Faustus' sheet and the post that I'm about to drop, but in short, I've been imagining that the undead empire mostly functions with a sort of barter system. Ghouls, aqua vitae, and various other less common commodities like weapons, armor, and tools are probably what get used in trade rather than precious metals or coinage, which I'm assuming would still be around yet have lost a lot of their inherent value after the fall of the living kingdoms. I think institutions like banking or the minting of new currency would presumably be nonexistent. 

I think that the undead empire is definitely quite 'hiveminded' or 'collectivist' in nature. Maybe you could think of it as a crony-communist-command economy sort of system with at least some semblance of personal property, since Faustus 'owns' lots of stuff. Or at least he [i]thinks[/i] that he owns that stuff in the traditional sense, even if in reality Eagoth/the undead as a whole own everything de jure, and therefore nobody really has personal possessions and Faustus and is just allowed to hold onto that stuff and peddle it by the blessing and goodwill of Eagoth.

If gorgenmast or somebody else who controls Eagoth wants to elaborate on how this actually is/how Eagoth views it in order to make the distinction that'd be fine by me, but I'm happy to just leave it somewhat vague and up in the air.
