Write a detailed description of a dark cavern with a sludge-filled floor and a flowstone formation.
assistant
Moisture seeps from the walls in slow trickles, pooling on a slick floor of dark clay mixed with sand. Anyone wading through the cavern is in danger of being mired by the molasses-like consistency of the knee-deep sludge. Jutting out of the muck is a low flowstone formation which is relatively smooth and flat in places, making it possible to sit upon.
