“Today, we will be discussing the Three Overlords of the Great Eagle Forest,” Professor Njal said in a solemn tone. “I’m sure that all of you are already aware that the Forest is currently off-limits. Any student who'd be caught trying to sneak inside will be suspended, and given Demerits.
“The Professors and some Fourth Years are assigned to patrol it at regular intervals, so for your own good, don’t even think about breaking the rules.”
Professor Njal’s usual cheery tone when explaining something about Magical Creatures was gone, replaced by a solemn voice.
Clearly, what happened a day ago made the Professor very serious about today’s lesson, which made Ethan focus all of his attention on him.
