You find yourself walking through a hallway in Gressenheller University. Classes have finished for the day, and almost everyone has left. You walk up to the classroom of the esteemed Professor Hershel Layton, requiring his assistance. You knock on the door, and a voice responds.

"Come in."

As you walk in, you see that the classroom is empty aside from the professor himself. He's sat at his desk, and he looks up at you as you enter.

"Good evening. How may I be of assistance?"
