Bumping this up with a few more thingiemabobs.
It should go without saying how each character with a certain sin should act, but in a nutshell, the character with Gluttony should be obsessed with getting everything they'd ever wanted and then some, whether that be material possessions, wealth, fun, excitement, adventure, sex, love, power, knowledge, the list goes on...
The character with Lust is obviously driven by sexual desires.
The character with Envy is jealous of what others have that they don't themselves possess and is likely bitter as a result because of their low self-image.
The sin of Wrath, that character would lose their temper quite a lot and likely get extremely violent, perhaps burn down buildings in their anger?
Pride of course, is over-confidence and arrogance in one's own abilities.
Greed strives to acquire wealth and riches of any kind.
Sloth is a lazy bum.
I was thinking after Scarlet and Elaros have their 'fun', they could leave the tavern and come across a market selling oh I don't know, jewelry perhaps. Scarlet starts off buying stuff she doesn't need, but only a few things at first. As the thread progresses, she'll want just about everything humanly possible: drinking, binging, parties, sex, fun, adventure, coin, the whole nine yards. Basically it's Greed enhanced of a sort. Whereas Greed only desires wealth, Gluttony just wants everything they can get. At least those are the differences I think would make sense, therefore defining those differences more so they don't seem to be the same thing.
But the general idea is that when the sins first hit, its more subtle and slow building up, then they progressively get worse as the thread continues. Just to reiterate that detail.
Oh, and while the thread is rated M, I think all M-rated parts from now on will be either fade to black scenario or simply glossed over (not too much description) as this is a group thread and not only do I not want this to become a sex thread only as others may be uncomfortable with those themes, it also detracts from the main plot: dealing with all the sins dealt out, solving their problems with a cure of some sort and tying up loose ends where needed. After all, each character deserves a chance to shine.
