Cora was in labour... Again. This time, with twins. She felt so guilty about having to give her first child up, but she had to, to give Cora her best chance. Her best chance at happiness, all of which said happiness was achieved by the deal she made with Rumpelstiltskin to teach her magic. Though the deal they originally made was that she give him her first born child with Prince Henry, the deal had been changed to state that Cora give him his own child during their short affair.
Later after the end of the affair, she ripped her own heart out, and brought it to Rumpelstiltskin saying that he told her to rid herself of the thing that was keeping her from happiness, and that her heart was stopping her. Two days before her wedding to Prince Henry, however, and before she ended that affair, Cora and Rumpelstiltskin did the deed. And two days later, the night after the royal wedding, Princess Cora and Prince Henry procreated.
In the months to follow, Cora soon learned she was pregnant. In fear that the child was in fact the Dark One's, Cora did an indepth magical ultrascan with her powers, discovering she was carrying two baby girls, one with a tattoo of a triple spiral on her right shoulder, and one with that if a crown. Instantly, Cora knew that the impossible had somehow... Happened. One of the girls' father was her husband Prince Henry, and the other's was Rumpelstiltskin. This meant that her deal to the Dark one had been fulfilled after all.
Cora made the decision to not tell Prince Henry she was pregnant with twins, and instead only told him of his own. She planed that when they day came that she would give birth to the twins, she would summon the Dark One and give him his child right away, so her deal to him will be fulfilled and Henry won't know. And besides, even if she did keep the child, it would probably become obvious to Henry that she wasn't his own. Also, Cora concluded that keeping this from Rumpelstiltskin would only result in an ugly fude. It was painful for Cora, knowing that again she would have to give another child up. But this was to give her, and both of her children, their best chance.
So when the day came months later, and Cora was laying in her bed holding her two beautiful, newborn baby girls, she summoned Rumpelstiltskin. "Rumple," She began when he arrived. "Our deal has been fulfilled," She continued, with tears streaming down her face. "This one is yours," She said, handing him the one with the one with the triple spiral tattooed on her little shoulder. Rumple gasped. Cora kissed the baby's head for the last time. "I love you baby girl," She said, to the eldest of the two twins, and let the Dark One hold his baby daughter.
"She's beautiful," he muttered, as he kissed her forehead. He knew immediately just by looking at her, that she would be his happy ending, his fresh start. After loosing his son, Balefire, through a portal to a non-magical world, he never thought he would ever love again. But his child... he could just feel it. And with her, there would be no need to hide his magic, for she had some of the most powerful magic he had ever seen, next to his own and Cora's. Then again, she was the product of him and Cora, so it was highly likely she had other unique abilities she had yet to discover. "What will you name her?" Cora asked him, as he pondered for a moment. "Desirae Morgana" Rumpelstiltskin replied, and continued, "Desirae, because I desired this child; and Morgana, because she will love the sea," he finished, and with that, he poofed out and back to his castle with Des, as Cora laid down in her bed, holding her newborn with tears streaming down her face.
