Crone of Cawdor

The  is a five-hundred year-old witch. She was turned into a hag and forced to live all alone on a mountain peak in Carpathia.

When Samantha was a child, one of her favorite bedtime stories was The Crone of Cawdor.

When the earth turns once around the sun,

Let the crone go forth 'til day is done.

Another's form she'll take and her form leave,

From six in the morn 'til six in the eve.

And in this guise if she can secure,

A willing kiss from a mortal pure,

To her will pass the mortal's youth,

To him will pass her age forsooth.

The crone sets her sights on Darrin. She takes the form of Terry Warbell, one of McMann & Tate's clients, in an effort to get close to Darrin, kiss him and steal his youth.
