LORE of the VAMPIRES
Like the Lycans, Vampirism is more so thought of as a disease. Those bitten by vampires have been injected with venom through hollow fangs in the Vampires mouths, and those who survive being bitten and are turned become something unholy to most . . . It's rumored they cannot go into the sun because it will burn them, and many were killed in fear.

TRAITS of the VAMPIRES
When bitten by a Vampire, there is a 50% chance you will turn, a 25% chance you will die, and a 25% chance you will not be changed. 
Vampires are well able to adapt, having sharpened senses and inhuman strength. They have fangs, and eyes that pulse red when hungry or around blood. They cannot be in the sun for too long or they may go blind, their eyes are only adaptable to the night and darkness. Vampires are great at using magic, specifically dark arts.
REPRODUCTION of the VAMPIRES
Vampire x Other Species have a 40% chance of passing on the Vampire bloodline, and a 20% chance of having a hybrid. 
Vampire females can only carry up to two children at a time.
