Pavanna removes the trinket from the fallen man and offers it to Kayleigh who with singed hair takes it, securing it about the pommel of her sword. As this goes on Jalil hops down into the chamber and takes a little more time to look about the room to be sure nothing is missed.
It seems the dam blocking the sewer water is built of all forms of dockside debris - old shipping crates, beams from what appear to have been sea worn, old bits of broken wagon wheels and smaller bits of debris all help hold the water back.
Examining the outline of the rat drawn out on the floor it appears to have been done with chalk, the edges smudged here and there.
The room is lit by a sole torch mounted in a rusting bracket secured to the wall. Near the floor is a small pile of other torches to replace the current when it burns out.
Beyond that there seems little else of interest in this chamber save the ladder leading further below.
