I saw no reason for y'all not to just stay here for 72 hours straight rolling three research checks a day.
Does shady woman (does she have a name?) come back every now and then to get more research supplies? If so, I can go out with her, back to the surface and get food or whatever if you people eat that, since it's still mid afternoon by my reckoning.
As for the missing scrolls, we know that nebta-khufre was here before us, and the library people moving stuff around was how we found out about this library in the first place.
Edit: Dear god this spelling is terrible. That's what I get for posting on my phone
