This side quest becomes available during the Attend Your First Day At Hogwarts main quest after attending both Charms and Defense against the Dark Arts class. To start it, speak with Cressida Blume in Central Hall at The Library Annex in Hogwarts. She’ll tell you how a charm of hers didn’t quite go as planned and ask you to retrieve her 5 flying books from the library.
Find 5 Flying Books
Head down the stairs near Cressida then take a right through the door there to enter the library. Her books can be found flying around various parts of the library. You’ll need to use the Accio spell to collect them. Check out the list below for a general idea of where you can find each book.
- Middle of the library on the ground floor
- Northeast side of the library
- Southwest side of the library and cuts over into the restricted section
- Second level northeast side
- Second level southwest side
Rewards
After nabbing all five of them, return to Cressida. If you hand them over without any fuss, she’ll reward you with some money and an Avian-Grey wand handle. Alternatively, if you ask her for a reward to keep her diary a secret, she’ll of course be mad. If you press her, she’ll say that she’s going to write nasty stuff about you but will fork over 300 Gold and an Avian-Grey wand.
