After their rest, the party packs up again. Eozindra consults the map and the group sets out, falling back into their established marching order (unless you tell me it's changed): Ishi and Elowin in front, Eozindra and Adran walking together in the middle, and Morik accompanying Elysia at the back. There are a couple of intersections, but each time the direction indicated by the map corresponds pretty closely to one of the passages. The tunnels have narrowed further, and the stonework is even older, but for all that, this stretch of the sewers are well-maintained.
But after an hour, the party has become accustomed to Eozindra's perfume, and they begin to notice an odd odor underlying the thick smells of the sewer. In addition, you spot that there are strange, dry slips underfoot, like scraps of oil paper or empty bits of sausage casing on the ground. Each PC who cares to can take a moment to evaluate all this by rolling a WIS (Nature) check...and let me know if you kindle a light to assist you in examining these things.
