Cole Turner once enlisted the Spirit of Rage; Andras, to help him destroy the Charmed Ones after he found out that the their powers were rooted in their bond as sisters. Andras used his power to turn long-simmering disputes between the Halliwell sisters into rage. Ultimately, the sisters' rage boiled over and caused a magically-amped cat-fight in which they used their powers against each other, severing their bond and causing them to lose their powers. This is reflected when the Triquetra on the Book of Shadows separates.
