I'm Prue Halliwell. Phoebe is my sister. The three of us were descended from a witch named Melinda Warren who was killed during the Salem Witch Trials. When the three of us are together, we're known as the Charmed Ones and can cast powerful magic. I died when I was 30 and came here just as it was about to happen so I suppose I will be 30 forever, not sure how that will work. I have a range of powers but my strongest one is telekinesis.
There is also a half sister Paige, who isn'here. She was responsible for the aging down spell a few months of go for those who remember that.
