Good question. As Augustus works in the Death Room, he might also have been tasked with research on resurrecting the Dark Lord. Which he could have done on or off the books -- however, you'd like to play it. But somewhere on our plot document we have notes about the resurrection ceremony from Book 4. So that's a thing that could happen.
A map making/order check in post will probably be happening on Wednesday. So he can make many connections if he'd like.
