I Guess you Could Call it Destiny

What if Mal wasn't really maleficent's daughter and she wasn't really from the Isle of the Lost? What if she was actually from Auradon and maleficent took her when she was 16 because she wanted a child to carry out her evil legacy? What if Maleficent erased everyone's memories to make them forget about their princess...BUT not everyone's memory was erased. The one person who remembered was her one true love ... Ben
