Melina and Judge sat inside the library, she was teaching Judge there because his house arrest had been lifted. She sat across the table from Judge, the table was rectangular and long. But they were both sitting across the long ends, so there was not much of a distance.
Judge was fully immersed in the book of creating principles, it mentioned the traits of ether and how it can be used to create one's own principle. After he had grasped the concept to a small extent, they would move on to the next class which was making one's own principles.
Creating a principle from scratch was a dangerous job, especially for children, but dragons never cared for their children as they cared for "privacy".
He was getting used to the nature of his species which was to 'provide safety, but let them do if they think they can'. While he liked the idea, he realized how dangerous it was if the person responsible for safety could not protect the child in time.
