Squeezing through the hole and pushing the rest of the way past the stone brazier, Phud gets up and out and, with Arden right behind him, spots the source of the trouble. Some of the thick goo much like the substance that had stuck his heavy mace to the kuo-toa's shield yesterday seems to have been glopped on the far side of the brazier. The adhesive is remarkably strong; with better leverage once he's up top and some exertion, Phud manages to push the brazier all the way to the side, though only barely. Certainly a creature less well-endowed of strength than he wouldn't be able to manage the feat at all.
Up top in the guardian room, Arden and Phud have a careful look and feel around and, aside from the dead kuo-toas seeming to be missing and the phosphorescent moss having been scraped off the wall, everything else is as it was left when they went below for their rest. There is no light up top, leaving Arden nearly blind.
