I just realized that probably 50% of you have not watched/read Vampire Knight.
Here are just a basic few rules.
1. Vampire aristocrats MUST obey the purebloods. Purebloods MUST obey the Vampire Prince and Princess
2. Hunters MUST try to kill any vampire they are ordered to kill (those of you that decide to be vampire hunters can make this into a very juicy plot *wink wink*)
3. The Discipline Committee is in charge of making sure the human's don't get too close to the vampires and discover that the Night Class is actually vampires. (however this is bound to happen)
4. Level E vampires are vampires that roam the town and have lost their humanity (you can use these vampires in 3rd POV to be attacking you/you killing them in plots)
5. A vampires bite releases an enomous amount of ectascy in the human's body
6. Vampires can bite other vampires to put their hunger at bay, or they can use the special pills that are given to them.
7. All aristocrats have ONE special power, make sure you list that one special power in your profile, pureblood lords can have three, Professors have 2 and pureblood prince/princess have ALL powers.
I recommend everyone watch Vampire Knight if you have time! It's available on Netflix! ;)
