They're now inside an indoors room, possibly an underground chamber judging by how one wall is rock.  There's a Mage's Sanctum enchantment, permanencied, about the whole area, and the border of a Forbiddance in front of her, with a very solid-looking and magical door in front of that.  It looks remarkably like the Chelish safehouse/prison, really.

There's a tiefling woman here, of scarred face, dressed as a rich man's maid might be.
