The God who answers after dark

You used to pray to the Gods after dark before you went to sleep, always thinking that you were praying to the good kind. The kind that showed mercy. However you were mistaken, as time passes and you grew older and wiser it will be revealed that your prayers were answered, but not by the Gods you thought you knew, but the dark kind. The kind that your grandmother used to warn you about. Ones you hear in stories. The kind that you should fear, but how can you when it's all you know. How can you when he was the only one who answered?
