Prudence Halliwell

Prudence "Prue" Halliwell is the oldest of the four sisters, who possesses the basic Warren Power of Telekinesis. She also possesses the power of Astral Projection, which allows her to project her consciousness into an astral form. Besides this, Prue possesses the basic powers of a witch: the ability to cast spells, brew potions and scry for lost objects or people. She can also access The Power of Four, the collective power of the Charmed Ones.

Background
Prue was born on October 28th, 1970, to the Warren witch Patty Halliwell and the mortal Victor Bennett. She started out as a happy, naive, and witty child who often argued with her younger sister, Piper, over toys or the usage of their magic. Despite her young age, Prue had perfect control over her birth power of Telekinesis, which allowed her to move objects using only the power of her mind.

Travelling Back to the Past
On October 17th, 1999, Phoebe received a Premonition of a young woman being killed by a Vampire. Frightened, Phoebe tells Prue about this. Paige says that the Premonition could be a vision of the past, and suggests that the four of them use a spell to travel back to October 17th, 1924.
