Sevenfold Mazework The Sevenfold Mazework was the center of all major dao activity within the Great Dismal Delve on the Elemental Plane of Earth . It served as both a trading center and court for the dao , in addition to housing the palace of the Great Khan of the Dao . Geography . The Sevenfold Mazework was actually an enormous labyrinth of tunnels , passageways , and chambers . Only the noble dao were immune to the " confusion " caused by the winding passages . Even minotaur slaves were not immune to the bizarre properties of the Sevenfold Mazework , and could easily become lost if they weren ’ t careful . Geographical Features . Elemental vortices and other portal s existed throughout the Sevenfold Mazework , connecting it to all of the other Elemental Planes . It was also linked to all the other mazeworks of the Great Dismal Delve . The entire area was divided into seven distinct regions , though only the noble dao knew with certainty what lay beyond the first region of the Mazework . First Region . The outermost region of the Sevenfold Mazework was populated by thousands of dao and even more of their slaves . The dao traded here with outsiders in the immense so - called Free Market . Almost all imaginable goods were for sale here , but the most important commodity were slave s . Stacks of glowing gems sitting atop great pillars provided light in this region . The theft of a single common gem was punishable by death since everything within the Sevenfold Mazework was considered property of the Great Khan . Every gem within the Mazework was marked with a special sigil indicating such . A " detect magic " spell would reveal the sigil . Second Region . The tunnels of the second region were blocked by massive stones that had to be moved in a specific pattern in order to pass . Muscular slaves were posted near each of these stones , ready to move them for their masters . These slaves only moved the stones ; they had no idea where the passages led , so questioning them for information was useless . Each stone held a large gem in its center that reflected light toward the next stone in line . If the stones were moved in an incorrect pattern , the light from the gems would not align properly and the stones became immobile . Minor dao nobles in the second region would serve as guides if they were bribed with enough treasure or special favors . Third Region . The third region was actually a pair of large identical halls , polished to a mirrored finish with metals . Most special visitors to this area were highly impressed by the craftsmanship presented herein . The mirrors reflected the many balconies and tunnels lining the halls , creating a mesmerizing effect . Every passage and balcony here was identical to all of the others , meaning that the inhabitants needed to specifically memorize their routes or become hopelessly lost within the passages . Large blue steel mirrors were rumored to be magical portals leading to the chambers of noble dao . Fourth Region . This region was a reverse maze , meaning that the end could only be found by walking through its walls and not down the passages . One wrong decision would lead the subject back to the beginning of the maze . Fifth Region . Glass and " walls of force " comprised the entire area of the fifth region . The exit to the fifth region was always visible , but the walls were not . Light was reflected in subtle patterns by the glass walls , clearly outlining any occupant to those viewing from the outside . Sixth Region . Earth gods were rumored to have constructed the sixth region in exchange for vast wealth . Shifting walls and floors created a puzzle that easily confused visitors . Those who were not blindfolded , including noble dao , ran the risk of permanent madness or even petrification from viewing the shifting puzzle pieces here . Light within the sixth region did not travel in a straight line . Instead , it bent and swirled like water . Only the Great Khan could safely view the bizarre sights within this region without experiencing adverse effects . Seventh Region . Tiny passageways , less than 1 ft . ( 30 . 5 cm ) in diameter , dominated the seventh region . Only small creatures , or dao in gaseous form , could traverse them . Another rumor stated that the Great Khan ’ s palace was actually a miniature , and his servants included tiny creatures such as mites and rats . The location of the central audience chamber , called the Hidden Fulcrum of the Dao , where the Great Khan held his court , was also a secret known only to the most high - ranking dao . Government . The Sevenfold Mazework was ruled by the Great Khan and his court , comprising the Dao Khanate . Trade . The dao traded all manner of gems and metals , most notable with the baatezu of the Nine Hells . Defenses . The noble dao had several elite military organizations that they could call upon if the Sevenfold Mazework was threatened , including : Inhabitants . 100 , 000 genie s and over a million slaves were rumored to live within the Sevenfold Mazework , though it was widely believed that these numbers were exaggerated to thwart invasion attempts from efreet or other hostiles . Rumors and Legends . A group of dao banded together to oppose the hated yak folk .
