Prue, Piper and Phoebe Halliwell moved into their grandma's house after inheriting it when she died. Then Phoebe finds an old book in the attic and reads the incantation and next thing they know they have supernatural powers and are now the most powerful witches in the world. Prue, who died in the third season, had the power to move objects with her mind and could also Astral Project. Piper has the power to freeze time and blow things up and Phoebe has the power to see into the future and the past and the power to levitate. Piper is married to her white lighter, Leo, and they have a baby boy. Phoebe was married to the source, Cole, before he was vanquished. With the death of there sister Prue, Piper and Phoebe find out that there mother and her white lighter, Sam, had a daughter and gave her away to a nun and told the woman to name her whatever she wanted as long as it started with the letter P. The nun named her Paige. She was in hiding until now because white liters and witches were never meant to fall in love and have children together, but with the power of three being broken she now must come into play to complete the power of three once again.
