Bone Hills - The Maw of Akarkhentkats

No secret doors or hidden stairwells; in this room or the one next to it that had the skeleton axemen in. Concealed in the face, at the back of the throat, is a narrow pipe that would have provided the original source for the water. It's long-dry, however, either blocked or whatever aquifer, well or cistern it is connected to simply doesn't have water any more either.

The rope descends down the shaft, hits the gold coins which shift and clatter against each other. They sound like real gold, if any know the sound of coins clattering against coins. There's also a shock, a blast of electricity directed over the coins. It might go up the rope to whomever may be holding it, but that's unlikely. Had the shaft still been filled with water, it likely would have been far more dangerous, the electricity spreading through the water to strike everyone nearby.
