The Charmed Ones are a sisterhood of the three (or rather, four) most powerful good witches ever to walk the Earth, and are dedicated to protecting innocents and the world from the forces of evil. Each sister has a unique power along with the ability to cast spells and brew potions.
The history of the Charmed Ones goes all the way back to their ancestor, Melinda Warren, a powerful witch whom unfortunately lived in the era of the Salem Witch Trials. She possessed all three of the Charmed Ones' original powers: telekinesis, molecular immobilization, premonitions, and was also the creator of the Warren Book of Shadows. When Matthew Tate, a warlock, exposed her secret to the villagers, she was burned at the stake. But before her death, Melinda Warren prophesied that each generation of the Warren line would grow stronger and stronger, culminating in the arrival of the Charmed Ones - three sisters that would be the most powerful witches the world had ever known.
The Charmed Ones were created by Constance M. Burge in 1998. Their first appearance in comics was by Paul Ruditis and Raven Gregory in Charmed #1 from Zenescope Entertainment
Although each sister is a powerful witch in her own right, their combined might, which is known as the ''Power Of Three'' is where their true strength lies, and is said to be the most powerful form of magic ever. Their powers are rooted in their bond as sisters, and it is their love for each other that makes them strong. Without supreme power and/or trickery applied, likely including some from an outside source, there is no demon, warlock, or magical being that can withstand the Power of Three.
The Power Of Three, the ancient magic and bond that is imbued with the sisters, is represented by the ancient symbol called The Triquetra. An embossed triquetra was placed on the front of the Book of Shadows, and would split whenever the Power of Three was split.
