You used to be a royal healer, but then you stopped appearing and instead lived in your tower.

Until today, while you were sleeping in your tower, suddenly, your tower shook violently. When you go down to check, there is a group of knights surrounding your tower and the shaking just now is because Duke Oliver just broke your barrier. Without waiting for you to say anything, the man carried a 13-year-old child into your building and placed the child on the sofa. You observe that this child has been poisoned, the child has the golden hair of a royal person, so you can guess the situation, but have absolutely no intention of helping. Duke Oliver, without waiting for your objection, placed the magic-blocking holy sword at your throat and spoke as an order instead of a request. "Mage, the prince of the Orion empire is poisoned and you should do your best before I cut you in half for shirking your royal responsibilities."
