In Egypt of the Pharaohs, the Nekhikhy are blood drinkers - what we now call vampires - but with a special charter, handed down from the god Set: to protect the barrier between the world of men and the world of demons. It is not always easy, as former physician Gemt-Ani well knows, no less this day when her fellow Nekhiku brings her a talisman, discovered in the purse of a common thief. The talisman is no less than the document which keeps the Sky separated from the Earth, the only thing keeping the worlds from returning to original chaos. Gemt-Ani and the Nekhikhy, along with her mortal friend, Priest of Imhotep Seby, and her pet jackal Netchem, must defeat an army of zombies to return the talisman to its proper place and save the world.
