If I'm not mistaken, Branch 'A' is the entrance to the tombs. There was a door
* at 'J' which Vsaati disarmed, but was unable to pick. Maybe enough time has passed for another attempt. We checked for secret doors, but found none. I'm unaware that we've found a key in any other part of the tombs, correct me if I'm wrong.

Though Hamburg wasn't there, Albricht suggested asking the three orders in the city if perhaps any of them had a key...
Maybe if we open the sealed doors we can find a key. Also, there was some weird cold in the main chamber we never figured out.
