@rezay I'm well, worked later than I thought today so I didn't get a chance to put up the OOC, but I am working on it.
That all sounds fine, as far as Devils go, they are stratified according to their intelligence and other properties. Red Devils are the most physically powerful, and likely to work for some scummy bank or mob or what have you. Blue Devils (aka Imps) are more common but even less intelligent than Red Devils.
Devils work based on bonds/contracts. Completing contracts (or weaseling out of them) his how Devils rise through their ranks, so they're usually enthusiastic to form contracts with mortals, though whether they actually fulfill their end of the bargain without betraying or killing their master is another matter.
