Binds two people as husband and wife
- "Not two but one, until life be gone."
- —A verse of the wedding.
A Dark Wedding is when two people are bonded together with the power of evil. In order for it to succeed, it must be performed in a cemetery at night by a Dark Priest. Additionally, the groom must drink the blood of the bride.
After becoming the Source of All Evil, Cole tricked Phoebe into a dark wedding after doing everything possible to sabotage their white wedding. He was told to do so by the Seer in order to assure his heir would be evil.
- Dark Binding is a similar ceremony.
