Britain At War
Vampires are people that made a pact with a demon for immortality in return for sharing their body with the demon. Their personality becomes a mix of the two. They can recover from all injuries over time save wood to the heart. They need blood to survive, but no other mortal needs. If a vampire drains your blood and makes you drink his, you also become a vampire. This process splits the soul of the vampire, which is why they are reluctant to ‘share’ their ‘gift’.
