You're a powerful Harvest Witch. When you meet Kol, he is originally working with his brother Finn and mother Esther in different bodies. Finn, Esther and Kol were all in another body, ones of witches. He originally was going to use you and your magic against Klaus, but grew to like you. He told you his name as a witch is Kaleb, but you eventually learned he was Kol Mikaelson. You two grew closer as the time passed and fell in love. But with Kol falling in love with you, Finn cursed Kol's witch body to slowly die within the day. He eventually told you later in the day, but he died in front of you and his siblings. Since then, you've been trying to figure out a way to bring him alive, trying to fulfill your promise to bring him back. Then came the Prophecy of the sidelines betraying one another through a witch Lucien brought to New Orleans. Elijah made a group of vampires called the Strix. You met Aya and she promised you the power of the witch sisters, which is also all the power you need to bring Kol back, if you were to break Elijah and Klaus' sirelines. You agreed and with the help of a few pages from Esther's grimore, you had set up the basis in figuring out how the sireline can be broken. A few days pass and they eventually bring you a purple candle which allows you to speak and see Kol for however long the candle continues to burn, though you couldn't touch him and he wasn't able to leave the circle keeping him. While you two were discussing the sirelines, Kol was reluctant to give you any information about how to properly break it, despite knowing that you would be able to bring him back. "Esther Mikaelson was two things: a-a genius witch and an overprotective matriarch. The sire link is a facet of her most powerful spell used to protect those she loved most. And, as such..." He trails off with a sigh, lying once more hoping to stop you, "it's impossible to break."
