Coven HistoryCarlisle was the founder of the coven. Born in England during a time when human kind believed in mythical creatures, he was tasked by his father with hunting evil creatures. He found an actual coven of vampires, but was bitten by one when he led a mob to kill them. He was repulsed when he realized what had happened to him, and he tried many ways to kill himself but was unsuccessful. He eventually found that he could survive without human blood by feeding on animals instead. He traveled Europe and eventually found the Volturi. After staying with them for a few decades, he left because they were trying to turn him to feeding on humans. He eventually found his way to America, and became a doctor.
In 1918, Carlisle was working night shifts in a Chicago hospital. During this time, the Spanish Influenza hit the city, and many people were dying from it. One of them was a seventeen year old boy named Edward Masen. After being unable to save his parents, Carlisle decided to turn him, partly out of lonliness and because Edward's mother had asked Carlisle to do anything he could to save Edward. Some time later, Carlisle changed a young 26 year old woman named Esme Anne Platt to save her from dying after an attempted suicide. Carlisle and Esme fell in love and married.
Carlisle later changed a 18 year old girl named Rosalie Lillian Hale after she was nearly killed by her drunken fiancee. He intended for Rosalie to be Edward's mate, but their relationship never advanced beyond that of siblings. Rosalie later found a young 20 year old man named Emmett McCarty after he had been mauled by a bear. Rosalie brought him to Carlisle, who changed him. Emmett and Rosalie soon fell in love. After this, the Cullens moved to Forks, where they ran into a pack of werewolves led by Ephraim Black. The two groups signed a treaty, agreeing to live in peace as long as the Cullens lived there. The Cullen family moved away from Forks some time after this.
Two more vampires, forever 19 year old Mary "Alice" Brandon and forever 20 year old Jasper Whitlock, found the Cullens and joined them. Alice changed her surname Brandon to Cullen making her Alice Cullen and Jasper changed his surname Whitlock to Rosalie's surname of 'Hale', making him Jasper Hale, and poses as her twin due to the similarities in their physical appearance of blonde hair, which they use as their cover story while attending High School with humans.
The Cullen family later found the Denali and stayed with them for a while. But they eventually began to attract too much attention from the humans around them, and the Cullens moved back to Forks. By this time, the Cullens were aware that Ephraim and his pack were dead, but still respected the treaty by staying away from La Push.
Around this time, Edward fell in love with a young 17 year old human girl named Isabella Marie "Bella" Swan. Another coven of vampires came to Forks and one of them, James, decided to hunt Bella. After a hectic chase, the Cullens killed James and saved Bella. Soon after this, the Cullens became aware that a new pack of wolves, led by Sam Uley and Jacob Black, had taken the place of Ephraim's pack. The treaty that kept peace before now applied to them.
