This magical pink crystal was hidden deep within Castle Grayskull and used by the Sorceress of Castle Grayskull. It provided her with the power to use her magic outside the walls of her Castle as well as maintain her Human form. She summoned it when she learned that the wizard Morgoth the Terrible had re-emerged on Eternia. Calling upon the aid of He-Man, she decided to confront her ancient foe at Dark Mountain.
