Al - library
The cardboard box, packed with as many books as his arms and magic could carry, was in Al's deathgrip.
He couldn't see Severus, or Dad, or Jamie and it was a crowded madhouse. Al carried his box as far as the library - not Severus', the public Hogwarts library, which was quite empty at the moment. He set the box on the nearest table, before starting the tedious task of taking out, expanding, and cataloguing the new volumes, with the quill which, prior to this, was only used by Al to proofread the Prophet contents.
Quickly, his table grew fortified with the towers of unpacked books, a miniature castle in its own right.
In times like these, some knowledge deserved to be public.
