I have a mojor question that I need to have answered. Is it true that Lilith was the first real vampire to walk the earth? Friend is bugging me about it and I can't get her to shut up...

According to some mythology, its true. I think its either in the bible or the old testimat that she was turned to evil.

Well I'm not really sure but there are some rather interesting stories about how were vampires originated and who was the first one.
I once read about the sisters Maya and Hellwise: In ancient times Maya and Hellwise were witches, but Maya wanted to be inmortal and so she created a spell where she had to drink the blood of a newborn. She did it and got caught so she ran away. Later on she realized that the only way to be alive forever was if she dranks blood to survive.
At least this is what I read.
