Nymph

Nymphs, often also referred to as Wood Nymphs, are good magical beings that frolic throughout the forest in the company of a satyr, spreading nature and protecting the eternal spring.

Nymphs are personifications of nature, and must be allowed to roam free in it or they "suffocate." They have the power to enhance and even create nature magically, such as healing a plant or making it grow stronger, or creating flowers out of nothing. They also have the ability to teleport by frolicking into trees and bushes, fading away into it. Nymphs are also the only ones that can transport (themselves and others) to the eternal spring, which they protect.

Nymphs Miranda, Lily and Daisy's satyr was killed by demons in 2003. While searching for their new satyr, they wandered into mortal San Francisco, and risked exposure. The Elders asked the Charmed Ones to investigate. ("Nymphs Just Wanna Have Fun")

After one Nymph was killed the remaining two transformed Paige into one to complete their circle of three. However, her true nature allows her to become a witch again. After they learn to depend on themselves to make decisions, they decide to protect the forest without a satyr.
