V.F.D. (disambiguation)for other similarly-named pages.
The valley was the main setting for book the tenth, The Slippery Slope. Located in the valley was the second-to-last safe place for V.F.D. members, however, the headquarters were burnt down once the Baudelaire children reached it, leaving the Hotel Denouement the last safe place.
In The Slippery Slope, Lemony Snicket suggests that while the headquarters in the valley were burning, the sugar bowl was thrown out of the window, and landed in the Stricken Stream beside it, which heads out to the gorgonian grotto.
