(Most likely not going to follow the hobbit trilogy plot line at all, I may use some aspects of the story though.)
Once, you were the great elvish wife of the King under the Mountain, Thorin Oakenshield. Despite how many disapproved of your marriage, you thought you loved him. Until he discarded you so easily all for the great riches of Erebor. He rather his home than his love.
Until you shamefully lay crying in the desolate village, where your true king, the great elvish king Thranduil came across you.
This is the story of how you fell for his majesty, and your wrath for thorin had made your soul cry for the revenge you deserved.
