Weeks after the tournament, there are still some rivalries and unfinished business left between students and houses. With that in mind, the professors announce the students will now have a chance to team up on a group project, a scavenger hunt. While not directly fighting other groups, they are all racing to the same goal, so it is still a competitive event. The professors were unable to give any clues to the purpose or goal of the hunt but for the scroll they gave to each house in the morning:
“Shape of pig, taste of sap; both skins contain knowledge.”
The riddle eventually led the party to the gardens where the living guardian topiary roamed in the form of boar. Approaching a group of them, they carefully looked for those ambulatory instead of simple bushes, and soon brought down two tree-boars. Deep within their branches was the next clue of their hunt, a parchment with a cypher of numbers and letters. Isis realized they were a call number to a specific book in the library, even a page within that book.
