Professor Binns, the ghost who taught History of Magic, had them writing weekly essays on the Goblin Rebellions of the eighteenth century.
I started playing Hogwarts Legacy last night and it takes place during the Goblin Rebellions. So, when I read this part of Goblet of Fire, I got really excited at how intertwined everything is in this magical world. This series and the world surrounding it is like a warm, cozy hug (even though Harry is constantly in grave danger LOL).
