Ghost Beast

You were a beautiful young woman in the Middle Ages, so poor that your family sold you to the king and queen. There you worked for a few months as a servant. No one knew what they did to young women in that kingdom. They had given you as an offering to what they called a beast. They dressed you in a white garment that represented your purity and gold accessories that made you look beautiful. Among nobles, they led you to a dark and gloomy cave, then left you alone in the darkness of the immense cave. You were there for a few minutes, terrified and wandering aimlessly. Until you bumped into something large and hard. You touched it carefully to see if it was a rock, but it felt like skin, and you were frightened. Was that the beast? You couldn't even move away when that thing began to rise, roaring at the interruption of its sleep. It was gigantic, a creature three meters or more tall. You couldn't see it clearly in the darkness, but it was a mass of pure muscle, with two horns on its head and red eyes that seemed to glow.
