Wicked Lady 

QUICK BIO
A nightmare marriage of hatred and the taint of the Dark Crystal, Wicked Lady was truly a terrifying construct. Slippery manipulation by the Wiseman convinced little Reeni that no one, not even her mother and father, had ever loved or cared for her, allowing negative emotions born of fright and homesickness to build within.
