The Triad

A consortium of very powerful demons who were behind the kidnapping of Christy Jenkins. They hoped to break Christy down so they could all share in the ultimate power for which she is the key. This is probably is the same triad as the one vanquished by Cole Turner in 3x07 Power Outage however in different physical forms.It is later discovered that The Triad cannot be destroyed as easily as previously thought. Their physical bodies can be vanquished but they continue to exist in spirit form until they are strong enough to constitute new bodies for themselves. Asmodeus is vanquished by Balie, Baliel is vanquished by Piper and Candor is vanquished by Christy. They are permently vanquished by the Charmed Ones in the last episode.
