Dark Curse

The Dark Curse was a created by Rumpelstitlkin. When used, the curse envelops the world in darkness, letting the person who used the ingredients (in this case, the Evil Queen) create a place of his or her choosing. Those who are the victims of this curse lose their memories while new ones are created when they appear in the new world (our real world).

The curse was created by Rumpelstiltskin, knowing that it would be used in the future at an unknown time. He traded the curse for something from the Evil Queen, though what he was given is still unknown. She then traded the curse for the Sleeping Curse from Maleficent. When the Evil Queen needed the Dark Curse back, she stole it from Maleficent, who warned her about the dangers. It was warned that the Dark Curse would leave a void within that could never be filled, and whoever created the curse had no morals.
