[She took the papers she had written up, noting that he had a lot of stuff written up in his own book.
Her notes consisted mostly of how some witches had natural powers they could call on without a spell or potion, and that those powers could consist of a variety of talents, her own being the ability to stop time and create explosions. However, not all witches had abilities like that, and that was noted as well. The lack of a natural power, however, did not mean there was a lack of magical ability. Witches could still cast spells and create potions when needed.
Her notes also had information about the purpose of witches, that protecting innocents (non-magical beings) was paramount, and that powers couldn't be used for personal gain.]
Looks like you've done a lot of research on your own.
[She nodded at his book.]
Though, that would be why you're teaching the class, I guess.
