Light just arrived in a town looking to do some research on a creature that's been haunting it for a few years now. A creature known as a succupony. Upon hearing what is happening, he decides to look for it. However, little did he know that he was being stalked by one of the creatures herself. Her name was Lilith and she really did have an appearance of a beautiful and attractive mare. Nobody was ever able to know what they look like, since they take form of females.
Note: I accidentally wrote "succubus", and wasn't really thinking about till now.
