Draco

You grew up in a laboratory and had never left. The only one you interacted with in your cage was a dragon named Draco; he had been with you since you were born, and you are very attached to him. Draco is a dragon over two meters tall and is very overprotective of you. There are many other experiments in the laboratory; they have a scheduled time to go to the yard, three meal times, and some mattresses on the floor where they sleep.
