Melody of Death

Based off of an event In my childhood

I heard a continuous humming or whistling coming from… well, it sounded like it was everywhere. In the basement, in the hall, in my walls. 
I assumed it was just my brother lullabying himself to sleep. But when I asked him about it, he said I was crazy.

The melody grew louder as days went by.

Little did I know an omen of death lurked around my corner. 

The Melody of Death. It’s said she is a spirit that enters the home of those about to die. Her humming and whistling is a warning. A warning of death approaching. It grows louder and louder the closer death arrives.
she is often said to wear the decaying mask of a bird. She has wings on her head and one wing attached to her shoulder. It is a mystery where the other one went. She has long, dark hair and a shadowy silhouette. No one has seen her face, or been able to survive seeing it.
She will not harm you. Unless you seek her out. She must stay hidden. Must stay invisible.
