A breed of demons vanquished in 2002, the Rigors were viewed as a threat to her son's Wiccaning by Charmed One Piper Halliwell. Knowing the Wiccaning would require calling the spirits of all the Matriarchs in the Halliwell family, Piper took precautions to eliminate all threats to spirited beings.
Although their exact orgins and powers are unknown, it is possible the Rigors capture, feed on or gain energy from spirits. Their method of attack is also undetermined but since Piper took the time to summon and vanquish them, it must mean they were powerful enough to cause great harm to the spirits that would be summoned.
Notes[]
- The name Rigor could come from the term rigor mortis; a stiffening of the body after death that is part of the decomposition process.
