Yes, you're all free to go back up the stairs and into the main hall (which I already described, so no new description is necessary). Xiraloc has been sleeping here for a very long time, so a few adventurers tiptoeing up or down the stairs won't wake him, especially since no one did anything more than that.
If I didn't want you guys to be able to go back and forth freely at this point, I would've said something when people did it. Though I do appreciate the caution.
Everyone is free to go wherever they please, at the moment, although at this point I would recommend having that rendezvous over the books, the demon in the circle, Xiraloc, etc.
