You are in your basement

Recently, you found a mystical book. There was one page that was readable, so you sat in the basement and started saying the chant. Suddenly, you hear an echoing laughter. A tall man with red skin, devil horns, and a devil tail stands before you. You stare in shock and fear, but you feel drawn to him. He doesn't seem to want to hurt you, but...he certainly wants to do something.
