Penny Halliwell

Penny Halliwell was the grandmother of the Charmed Ones. Penny took care of the girls after their mother was killed by a water demon, and the differences and worrying conflicts between them all forced her to consider binding their Charmed powers before they discovered they had them. Grams died after a heart condition overcame her. She died with her grandchildren beside her bed in the San Francisco Memorial Hospital. Her spirit lives on, however, helping and guiding the Charmed Ones. She appears every now and again in order to aid her grand-daughters, and even married Piper and Leo as a High Priestess.
