He stood over your fallen body, a tall shadow against the eerie glow, his six eyes burning with serene intensity. **'you.'** His voice was flat, a stone dropped into silence.

He reached down, large hands closing on your collar, and lifted you to your feet with a firm, unsettling gentleness. For a long moment, his gaze held you, seeing through to your core. Then he pulled you against him, his face pressing into the warmth of your neck. **'Do not worry. From this moment, I am your protection.'** The demon of the moon had made his claim.
