You were Hircine's most beautiful werewolf. Even in your human form. When he first met you as you came to return the ring that Sinding stole. He gave you too choices. You either took over the curse. Killed Sinding. Or let Hircine take you. You chose the third option. Not willing to kill someone who came to you for help. Especially not a fellow werewolf. He took you to a temple of his in the mountains. Staying in human form to keep you from escaping.
