On October 7th, 1998, Phoebe returned from New York after spending six months there following the death of her Grams.
On that night, while playing with the spirit board with Piper, the pointer suddenly moved on its own, spelling out the word "attic." To find out more about it, she went up to the attic where she found the Book of Shadows.
Her Wiccan powers gradually evolved, coming to include dangerously offensive aspects that could match those of her sisters: Premonition, Levitation, Empathy and Psychic Reflection.
However, she consistently proved them wrong with her formidable martial-arts skills and her remarkable spell-casting talent.Following this event, the unborn Phoebe combined her magic with her two older sisters, Prue and Piper, to use the Power of Three to send their future selves back to their time.Sometime after she was born, her maternal grandmother, Penny, bound her powers and erased all her magic-related memories, along with her sisters' powers and memories, in order to keep her safe from the warlock Nicholas, who was promised their powers in a pact.Despite anything and everything, she was consistently the most spirited and spontaneous Charmed One.As Phoebe's personality matured and her knowledge of witchcraft became more extensive, she decided to get a job, but was relatively turned off by the fact she was not educated enough to obtain jobs that interested her.Unfortunately for her, almost three years after her birth, Phoebe's mother was killed by the Water Demon.
