In case your memory of Charmed is a bit fuzzy, the show, which aired on The WB, ran for eight seasons from 1998 through 2006 and featured Combs, Milano and (originally) Doherty as sisters Piper, Phoebe and Prue who find out that they’re the most powerful good witches of all time and have to use their considerable powers to protect humanity from a wide variety of supernatural bad guys like warlocks and demons.
Prue has the powers of telekinesis and astral projection, Piper can freeze those around her and also make evil objects or entities explode, while Phoebe has the gift of premonition.
