The group of you manages to make it to the top by quickly. The trench bisects an enormous cavern with a 30-foot high ceiling supported by naturally formed stone columns. There are bridges leading over the trench about 40 feet to the North and South. Continual Flame spells cast on stone lampposts reflect off crystals embedded in the walls and ceiling, illuminating myriad fountains, waterfalls, streams, and pools. Water drips from stalactites onto leather tarps covering clusters of merchant stalls west and east of the trench. Beyond these marketplaces are well·tended gardens of mold and fungi, crystal walkways, and stone bridges. The tranquil beauty of Mantol-Derith is undone by sounds of combat to the northeast, where you hear the thunderous boom of metal against stone and see panicked svirfneblin running from 8-foot-tall duergar.
