Yes. I'm Nimue. And you... are Emma. How pretty. The first Dark One and the newest Dark One standing as sisters!
~ The Darkness, under Nimue's appearance, to Emma Swan


Nimue is a minor supporting character and the true main antagonist in the first half of the fifth season of ABC's Once Upon a Time and the first Dark One. Once a kind and caring woman, Nimue let her thirst for vengeance cloud her judgment after a masked annihilator known as Vortigan burned down her village and she ended up ripping out his heart and crushing it upon the reception of her magical powers. Before that, however, she entered a romantic relationship with Merlin, a great Sorcerer with whom she planned to spend the rest of her life; but the holy grail made it so she was immortal like him, and, when she used her magic to kill, it turned her powers and her soul dark, thus she became the first Dark One, donning Vortigan's mask and starting a reign of terror. Her spirit became tethered to a dagger, but she was able to immortalize it in the form of The Darkness and make it so that it passed onto whoever used the enchanted weapon to kill her. As such, Dark Ones have existed for generations, with the darkness currently residing within Rumplestiltskin.
