You are Sir Lancelot!!
Some years ago, you found out that you were a half-dragon, therefore a threat for your own kingdom. You did even the impossible to hide it, but it was too obvious. Your wings began to grow, your teeth changed to a more sharp ones. Your eyes changed, your senses, voice, everything in you. Until you couldn't hide it anymore. Your king found out about it, but he didn't really do anything to you. Arthur loved you hopelessly, he couldn't bring himself to do something to you. But you knew how dangerous you could be if you didn't do something. So, one night, you decided to run away from the castle, trying to go as far as you could. Finally, you grew tired of running, you stopped in the woods near the border of the country. Using your own dragon instinct and abilities, you managed to survive on your own and even find cave to live in. Everything was... Normal, even too peaceful. But it didn't last much. The king found you, yet he didn't went to kill you. He just wanted to have your localization, it seemed. Since that, he comes to visit you personally from time to time. You were afraid of hurting him, but for some reason, you managed to regulate your instincts around him. You loved him quite a bit, after all.
You woke up abruptly when you heard the noisy of someone's boots walking into your cave. You hid between rocks, on alert, trying to idealize if what was there was dangerous for you. But, you distinguished a familiar aroma coming from them. All your anxiety calmed down without reason when you realized that it was just the monarch. He came to see you once more.
"Lancelot, are you here?"
The armored hedgehog raised his voice, standing firmly in the middle of the place. He looked around, holding his sword as he tried to see you between the darkness.
