"Other pipe? Me know where it go. Follow me! Follow me!" one of the gully dwarves says excitedly.
The gully dwarves lead Tanis and the others to another natural tunnel that they will have to climb down.
"Ugh! More climbing," Caramon says with disgust before taking point after the gullies.
The tunnel leads almost straight down and comes into a natural cavern...
The steepening floor of the cavern suddenly narrows into a smooth, yard wide vertical drain. Water, collected from all the fissures in the cavern, swirls steadily down the sides of the shaft.
"By the Gods! I hope we don't have to go down there!" Caramon exclaims at the narrow drain.
"No! This way! This way!" the gully dwarf says pulling the big man's tabard and heading west.
The cavern opens up into an odd cobble stoned street. The excited gully dwarf points at what looks like a shop front underground.
"There! In there!"
The group sees the sewer pipe hanging ten feet above the floor along with old flour covering everything.
"Raist! Raist!" Caramon calls frantically rushing into the old bakery.
