Corin watched and waited, his loving, focused gaze resting squarely on the twitching form in front of him. She was the only thing that held his attention- no earthly influence could sway his gaze, not even his growing thirst. Under his gaze, she seemed to glow, a beautiful unearthly light within her very being. Corin knew not what force compelled him to change her, but all he knew was that he had to save her from her otherwise certain fate.
"What pretty things you have brought for us to play with," Aro drawled. "You have done well, Heidi. And now, let us feast!" Corin leapt for a young woman, and he had her neck within his jaws when he truly smelled her, saw her face and gazed into her frightened eyes. He stopped, shocked at the feelings suddenly thrust upon him through her intense gaze. And all he knew was that she was part of his soul, and she must be protected at all costs. Looking around and finding the others occupied with their meal, his instincts took over and he quickly tucked his newfound soul into his arms and swept her from the room, covering her eyes from the scene they were leaving behind.
He had bitten her carefully in a secret room he had unearthed during his years of service to the Volturi, a place he considered his own and only his. He didn't even know her name- there had been no time to speak as he had taken the only action he could think of to ensure her safety. Now, she lay before him, and he could not tear his attention from her for a second. His thoughts were consumed with her and all that he didn't know about her and her life. Never before had he given his victims a second glance or thought- no longer just meals to him. He hoped she would accept him and her new life, but he would do anything to make her happy, even if it meant letting her go. It was enough for him that he knew she was safe now, and any time he could spend with her would be an extra blessing.
Days passing ceased to mark time. Corin felt the passing of time through the shuddered breaths of the changing creature before him. Her writhing form was showing signs of her change- her skin sparkled with diamond-like facets, and her features had shifted ever so slightly, making her even more beautiful than she had been before. Corin kept his vigil through her every shudder and drawn-out gasp, until it seemed that she was nearing the end of her change. He knew not how many days had passed- his sanctuary had no windows and only a single entryway, which remained firmly closed as Corin leaned against it. Slowly, her breaths became less frequent, and her shudders more intense as her newly changed body completed its metamorphosis. And suddenly, she opened her eyes and shot to her feet, faster even than usual vampiric speed, and her body clenched in upon itself towards her chest, arms and head forced upon her breast by an internal force. Corin, worried and confused, darted to her aid, trying to steal a glance into her eyes for a hint at what caused her such unusual pain, and as he met her eyes, her shoulder blades exploded in a burst of white and cream-tipped feathers (Feathers?!?) and her wings burst forth into the small space Corin and his angel had shared for the past few endless days.
