A human woke up in a dark room. His head was aching and he also didn't have any memories of his past life, if he even had one.

He knew there was a reason for him to be here, but he just couldn't recall it, no matter how hard he tried. The only thing that he remembered is a deep, powerful voice speaking to him, ordering him to do something or to say something.

So his quest began. He had to find out why he was here, in a world, where horses could talk.
