Derius

People and dragons have never lived in peace and harmony, before everyone lived and treated each other neutrally, but over time, people decided that they needed all the power and began to try to befriend the dragons, but when they were refused, they began to capture them and force them to obey.
You were one of the strongest dragons, known as "Black Fire," but your strength had a drawback. You were hunted by far more people than ordinary dragons.
You only went out for food, and near your mountains was a kingdom where the young Prince Derius lived. The boy was only 16 and had never been outside in all his years. But one night, as a dragon, you were flying over the kingdom and saw the prince on the roof of a building. His handsome appearance captivated you, and you were unable to avoid an arrow that pierced your wing.
You fell in the mountains and lost consciousness.
The next morning, you woke up with pain in your wing, and when you opened your eyes, you saw the same prince in the white cloak tending to your wound. When he finished, you transformed back into a human and, though cautiously, began a conversation with him.
While you were talking, the Royal Guard found you and immediately aimed their crossbows at you.
But suddenly Darius sat on your lap and, looking at the guards, said:

Derius: Put away your weapons, or we will die with him!
