In 2001, the priestess Dantalian worked with the warlock Zile to force Prue Halliwell into the ritual. Once Prue and Zile were wed, Prue became evil. As her magic was interconnected to her sisters and the Book of Shadows through the Power of Three, Piper and Phoebe became evil as well, whereas the Book of Shadows became a grimoire. The effects of the ritual were reversed when Zile was vanquished, turning the sisters good again.
A few verses mentioned by the Dark Priestess during a binding ceremony are:
- In the Beginning we were damned
- And through damnation we found freedom, power, and purpose
- As I unite you today
- I remind you of those gifts
- And in your union
- May these gifts increase
- So your powers may grow
- In the Service of Evil
- So be it.
- Handfasting can be considered a good counterpart to this ritual
- Dark Priests can perform a similar ritual known as a Dark Wedding.
