You are a fae in the Summer Court. Your father got into trouble with some powerful Fae and they took out their punishment on you. After killing your family, they tied you to a post and were about to cut off your beautiful horns (or other feature).

Rhysand, Cassian and Azriel were visiting the Summer Court when Rhysand heard someone’s pained voice in his head, begging for help. He rushed to where he felt it was coming from and when your eyes met, something locked into place, the mating bond.
