George

George was a vampire who lived in the 1300s. He was the creator of Alistair.

George loved the idea of taunting humans by making them believe that he was a prince from Hell. He led on humans in love with the occult, asking them to sacrifice everything they held most dear in exchange for his supernatural assistance, because he liked to see how far humans would go for their goals.

Alistair's father wanted to make his son king of England, and believed that George, who went by the name Astaroth by that time, could give him that power by changing him into a vampire. After Alistair arrived in the secret tunnels of London, George gave him a few pointers: to stay out of the sun and avoid drawing too much attention, then he bit him and disappeared.

When Alistair returned home as a newborn vampire, he found the house empty and realized that his father had made the deal of transforming him in exchange for the rest of his family to George.

It is unknown if George is still alive in the 21st century.
