Here is something I whipped up in a few minutes. I will add more later.
Prolouge
A piercing shriek erupted from the maw of a beast, racing through a village. Men cowered in fear. Women in children held each other for comfort. There was no escape. It would come and hunt them down. A sudden breeze blew out all of the village lanterns. The only light left was the full moon. Its light was a source of pain for the villagers. The moon seemed so close that they might be able to escape from the horrendous, yet it was so far away. It taunted them.
They knew that soon they would be stripped of all life. Taken away from the very things they knew and loved. They would instantly be gone from this life, into whatever awaited them after. They said their last prayers.
Another shriek filled the village. Yes, tonight they would be gone. There was no hope. The Krakzah were coming.
Okay, so I am looking through here, and at first I see things such as, "MORE!i'll be waiting for more updates. sounds like a potential story. comparable to many of the books i have read before the words you used were strong and descriptive."
But then I started reading review such as, "It is a very generic sounding story. Like almost all the creative writing essays i did as a kid. All action and no charcterisation. Unless you are planning to write an entire book on the internet which i dont advise you to do then this isnt great. Its ok though. Youcan tell that you are keen and have an active imagination. Dont give up your day job though."
