>Produce dousing rods.
>"Thanks."
>Guess we'll make do from here.
>Sample the air with our nose.
>Visual scan of what we can see for anything that looks conspicuous.
>Sweep for indications of mice.
>Dousing scan.
>You take your dowsing rods in hand.
>Then you thank Louise. She gives a very subtle nod of her head, but doesn't take her eyes off you.
>It does seem this is where she wants you to stop, so you hope it'll do.
>You take a sniff of the air. Aside from Louise and the other people nearby, you can pick up hints of a few potted plants and, from the filing room in particular, the smell of old wood and paper - nothing that seems the slightest bit unexpected
>You can't see the interior of the room all that well from this angle, particularly as packed with filing cabinets as it is; ones near the entrance mostly obscure ones further in. You can see very little conspicuous other than that. It is possible there are other features or even people further inside the room, but nothing you can see at the moment. There is, however, clearly a very significant amount of records kept here.
>You don't smell any mice nearby, nor detect any of the other telltale signs of their presence.
>More mundane senses out of the way, you sweep the room with your dowsing rods. There are some quantities of metal, but nothing precious or unusual, nor any other materials that strike you as out of place. You sense a faint magical resonance over whole of the room, but upon closer inspection it feels rather like a simple ward of some sort - possibly against fire or water, or maybe some sort of alarm system. They're not altogether unusual, and it wouldn't surprise you if a building like this had some within it. Narrowing your focus, you trace very slowly across the contents of the room, looking for something more specific that might set off red flags about a particular document being tampered with. Try as you might, though, you come up blank on this front. If someone has pulled off something of that nature, you're not picking up any obvious sign of it.
