Professor Boatbell's friendly behavior and passion for the subject helped retain interest throughout the lesson. His many questions also kept the class engaged and allowed most students to show their knowledge.
The initial topics were rather dull. Professor Boatbell's explanations started from the First Impact and barely covered half a century by the time the class was over. He had to establish a good foundation before moving to specific matters, and Khan felt he did an excellent job at it.
The Professor didn't talk about the invasion. His subject focused on how humanity adapted to mana, so the war wasn't important. Instead, he went over the first attempts at employing and wielding that energy to give insights into what had worked and failed.
