>Your treasure sense is definitely buzzing more down here than it was above ground, but you'd need to be a little more slow and deliberate to discern anything that could count as a trap; you don't have any preternatural awareness on that particular front, as handy as it might be to have.

>The room is modestly spacious compared to the landing, though still retains its cloistered feel. It is arrayed neatly with locked glass and oaken cabinets, inside of which rest thick tomes and slim aged volumes, bound in leather and hide and even metal, each bearing the scars of time to one degree or another. Many are in quite good condition, though others are so tattered that their spines are barely readable. Nestled between the cabinets are several small reading desks, each with a brass lamp and straight-backed chair, but there is little other furniture or decoration in the room. It also appears to be empty, save for the two of you.
>As you enter, you note the librarian pass her hands between a pair of etched metal fixtures attached to the wall, looking rather like two halves of a silver moon.
>"Put your hands in there," she says.
