"There’s beauty hidden in the darkest of places. Too bad no one can see it there."
— Sosiel Vaenic, Cleric of the Fifth Mendevian Crusade
Once underneath Weeping pond, T'Sarra finds it rather easy to hold her breath and find her way, leading the rope as she swims ahead of the others in the brackish, sulfurous water. Though the murkiness of the pond makes it somewhat difficult to see, it doesn't take her very long to find a the submerged waterway along the northeast face of the underwater escarpment, about fifty feet from where they had entered the water.
Though the underwater stream through the tunnel is fairly placid, it does wind through a slightly sinuous path, and the lack of light makes this part of the swim a particularly daunting challenge, as now the tiefling is restricted to not only relying on her darkvision, but also for trying to see through a semi-cloudy body of water.
The tunnel goes on for another maybe forty or fifty feet, until finally clearing upward to a bitter air pocket stinking of mold and vinegar that leaves an unpleasant flavour in the mouth.
Here, dampness hangs in the air of the lightless cave, condensing into heavy moisture on the slick stone walls. The calm, dark waters wind around the corner northwards, then again to the east further up north along a stony, soot-scarred beach. A five-foot high ledge sporting several stalagmites rises to the east, beyond which a low-ceilinged cave beckons.
