History
Hundreds of years ago, during the time of Agnes Warren, the Warren Family became aware of a warlock who was killing innocents and witchs, so the Halliwell Ancestors tried to find out who the warlock was. When they narrowed it down to one suspect, Timothy McBride, Agnes said that their suspect couldn’t be the right person. She claimed that Timothy was her long lost brother and she protected him from the rest of the family as long as she could. Finally after alienating the whole family and creating hard feeling that still haven’t passed, Agnes realized her mistake. (Agnes was trying to find a sister Brianna Warren, divination with the help of an enchanted mirror. When Timothy happened to pass behind the mirror. While he seemed to be pleasant and beautiful, she saw who was really in the reflection). Timothy had tricked her into thinking he was an estranged brother. Agnes told the family about her mistake but still refused to tell them where the Timothy was hidden. Agnes went up against the warlock Timothy by herself. But by then, Timothy had become very powerful by draining the powers from his victims. Agnes finally won the battle, even though the injuries she took eventually killed her too. After she vanquished the warlock, the killings stopped.

Philippa Warren was very elegant and wrote a diary in the Book of Shadows stating his disapproval at the sister Agnes.
