Can't think of a name for this, any ideas? 

Dear my fellows
I shall let you know
That what I do here is just me

I stalk my predators
And scare them at night
I make a feast of their bones
And feed off their fright

And their blood keeps me fed
I take most of them
But keep some for you

I like to see your faces
When you find the present I've left
In all of its places

And then comes the screams
That howl in the night
Their pitch full of fright
Just because of what I left
