These are probably only some, there are probably more:
- Don't drink in public.
- Never tell anybody about vampires who may be a danger to them.
- Never stay in one town for a long time if you have been a vampire for a long time otherwise people will start to notice that you are not ageing.
- If people consider them as dead and not living (normal vampires are considered living) then they must leave where they live otherwise people will know that they are not dead.
- They cannot turn people who are already dead into vampires as they cannot mess with the other side.
