Shaya'Nor
 
--> Think fantasy-realm Transylvania without ripping off Ravenloft. Really, the setting of "Van Helsing" with a little less tech and a little more magic. Vainar is their main god, and the Thirteen Necrolords are the remaining pantheon (doc attached). Cities are mainly ruled by vampires and werewolf lords, though there are a few liches in power here and there. 
 
A note about vampires - When they are first created, they are still pink and normal-looking, for the most part. As the corruption takes hold, they start to darken, ultimately turning black (I use drow figures to represent most vampires). True masters regain the ability to lighten their skin and "pass," though they remain pale.
 
The "upper class" are the Shayakar, those of the Fae blood who followed Vainar in his fall. Humans are pretty much peasants unless they are lucky enough to come from one of the really old families. Most vampires are actually from Shayakar stock, though some humans are still chosen. The old and powerful vampire families maintain control of their living bloodlines, culling out the weak and choosing the most fit for embrasure.
 
Other races (unless they are of the corrupted variety) are more or less shunned or barely tolerated. In particular, dwarves are hunted and killed within Shaya'Nor's borders; their corrupted "cousins," the boggans, hate them with deep passion. Trolls are the corruption of goblinesh (thus there are three sizes of trolls, and they are NOT of the D&D variety, but closer to classic literature).
 
Other creatures of undeath and corruption come and go pretty freely in Shaya'Nor, so feel free to play that up. I am attaching a doc detailing the Necrolords (and other greater beings, as well), so you know what kind of undead and Darkness critters there are.
