Chapter 1: Parlour Tricks
The northeastern tunnel was horrific. Frilia and Felix hadn't gotten more than a dozen steps in before they found themselves having to slow their steps to keep their footing. And it wasn't due to the webbing, though there was plenty of that.
The first time Felix slipped it was because something thick and wet and ropey rolled under his foot. The second time it was because the wall he used to steady himself with one hand quivered when he touched it. Frilia, with her smaller and more nimble feet, had a slightly easier time, but that didn't make it any more pleasant.
There were fleshy tubes all throughout this tunnel, covering the walls, the floor, and the ceiling, if the goopy stuff that fell on their heads was any indication. They ran in rows, all heading down the tunnel towards its terminus.
The tubes diverged as the tunnel opened into a small chamber, no more than 25 to 30 feet across. As the tubes ran along the walls and the ceiling, they converged on a point on the opposite wall, where the hollowed out husk of a cocoon hung high. The body of an ettercap lay unmoving at the base of the cocoon.
Strewn about the room were disorganised piles of body parts -- humanoid and spider alike: an arm here, a leg there, a mandible, even the skinned face of a drow.
Through all of that, the thing which dominated the chamber with its presence was the gaping hole in the center of the floor. A gradual slope lead down to an opening perhaps 5 feet wide, and a slick tunnel heading down to... no obvious destination. The tunnel turned shortly after its descent, so its destination could not be determined. Spread around the opening of the hole were several spider-like legs and mandibles, but these were different, covered in reddish-black barbs and spikes, and artfully arranged so that the hole looked like a spider itself -- with legs far too long for its body. One of the legs and one of the mandibles were slightly out of position.
