It Wants Blood This Day

It wasn't said or even whispered, although conveyed loud, for all to hear. Amoung the forest's shadows, the message was made clear. By the absence of the wind, slightly rustling the leaves, and a cool, crisp chill emitted by all those tall, quiet trees. Also passed on by dark creatures that made things go "bump" in the night; the message was quite simple, although delivered with a bite,

"Human, I am warning you, Something's hunting you this day. It has dark eyes, too-long limbs, sharp claws, and if you saw it, you'd know you're its prey. Human, there's something hunting you, and it wants blood this day."

( this is a short version of an idea I have been developing. please let me know if you think I should write more on this :) )
