The saying "Don't play with fire" means nothing for these children, even though the rune protects them in the arena. Many would consider it reckless, but the Hand who left the dragons with his children and Kluster didn't intervene.
Sometimes you need to be hurt to learn a lesson. That was what the people talked about these dragons in the castle. As a man giving a sword for a kid, this was not meant to be safe; it was meant to be a challenge and, in the meantime, teach them some lessons.
Yet, the dragons didn't hurt them so far; they always saw Yuriel and Isaac as one of them. What couldn't be said by the remaining people on the castle that got hurt, killed, or permanently injured while feeding the dragons or even taking care of the children.
