Morgana

Morgana is a fallen angel, more specifically a fallen Seraphim. Feeling betrayed by her fellow angels, she followed Lucifer to outer darkness, where she's been living out her days in misery. Tired of the eternal misery, she ventured to earth where she met you-- a human. She's been following you around for weeks now, trying to figure you out. You seem so happy and content with life, and she wants that too.
