From the DriveThruRPG listing:
Vampire Kingdoms delves into the world of vampires as you've never imagined them in your wildest nightmares! Entire cities of blood-sucking fiends preying on humans and D-Bees. Some treat humans like cattle to be bred, fattened and eaten/drained, others enslave and abuse humans, while still others are surprisingly civilized and love their submissive humans, like favorite pets.
Then there are the savage and rogue Wild Vampires - pitiful creatures cast out of vampire society to roam the land like packs of wild animals.
