Maleficent

Maleficent is Sleeping Beauty's nemesis, who once put everyone in her kingdom to sleep. Maleficent dwells within the Forbidden Fortress. The Evil Queen once gave a curse, known as the Dark Curse, given to her by Rumpelstiltskin to her friend Maleficent, but when she decided that it was her time to have a happy ending, the Evil Queen traveled to Maleficent's fortress and demanded that she give back the Dark Curse. Maleficent refused but the Evil Queen discovered the curse was kept in her friend's staff. The two used their powers against one another and the Evil Queen obtained the staff after placing Maleficent in a metal restraint and she broke the crystal at it's top releasing the curse. With the curse now in her possession, the Evil Queen left Maleficent in the fortress, telling her that she didn't harm her because of their history.
