"Do you know, it just occurs to me. There are vampire legends on almost every inhabited planet."
- The Doctor. Doctor Who: State of Decay
The same could be said of every culture. Today let's go to a country so over run with vampires, ghosts and demon it is a wonder that there is any room left for normal humans.
China might not be your first thought when it comes to vampires, but really it should. We are going to spend a lot of time here.
The Hisi-Hsua-Kuei or Hsi-Hsue-Kue is a demonic spirit that inhabits the bodies of the recently deceased. The spirit is completely foreign to the host body and has no memories of the body's life. It is simply an animalistic monster out to drink blood.
Killing the body will stop the problem temporarily but the demonic spirit will move on to another host to start over. A priest must perform an exorcism on the vampire while the spirit still remains in the body in order to force it completely out and back to the hell it came from. Alternately a cleric can also "turn" them as if they were a "Special" class undead. If they are high enough level for a D result then the monster is truly destroyed.
This creature must return to it's grave site by daybreak or be destroyed. Like other vampires it can also be destroyed by running water. Holy symbols and incense will ward it off, holy water will damage it.
Also like other vampires the Hsi-Hsue-Kue cannot enter into the private homes of others or enter holy ground.
