Today’s clue was
“What is the number of the chapter in which Professor McGonagall cancels the Quidditch match between Gryffindor and Hufflepuff?
Multiply this number by 42.”
This answer is 588
The answer would have been found in chapter 14 of the Chamber of Secretes. So you would take 42 and multiply it by 14 to get 588. Then you would add this to the URL of quill.pottermore.com/588 and then you would search through the photos to find the Magical Quill. As some of you might be wondering about the time, it is 5am Eastern Time. This is the time in which it came out this morning.
