Searching the main floor would reveal a couple of passages that lead to a lower floor; where she had smelled the troglodytes, earlier in the run, after the first run-in with Kikonu. There were a few routes she could use to descend into the depths, but either way, they would arrive in the basement of the castle. A decent portion of it seems to have been evacuated; from the smell, likely where the troglodytes once made their lair (Areas V1, 2, and 3), leaving them in a long-abandoned kitchen (V4), thick layers of dust covering the long-cold hearths. Exits to unexplored areas lead north, south, east, and west.
