Keiran's last class of the day was due to start in a few minutes, so he left the Professor's offices and headed down the hall with a bag in his hand, hanging at his side. Though the bag held nothing but a few sticks, it weighed heavy in his hand. The lesson would be one to test both the students' skills as well as their patience. It would be quite an adventure if he was correct.
There would definitely be consequences if the students weren't paying in class that day. And Keiran knew it wasn't just House Points hanging in the balance. There would be a bit of panic involved in an incorrectly casted spell. He would have to deal with that if the time came, though, so he pushed it to the back of his mind for the time being and opened the door to his classroom.
Professor Hayes left the door propped open as he moved to set the bag on the front desk. He turned the chalkboard around before nonverbally casting a spell to write the lesson on the board for him. He walked around the board to return to his desk at the front of the room.
