The walls were once slick with condensating excrements and the scent of feces was an inescapable force that lingered in the air at all times. Now, the sewer corridors are as dry as the desert above them. Putrid scents come and go as the winds blow through galleries of semi-petrified masses of ancient feculence - or the scents are carried from fresher excrement after the wind passes through corners of the sewers reserved for stews of waste and rotting dead of the present day.
These corridors, once solely the home to pests and shifting excretion of the old age, now house the people who could not bear the striking heat of the dual suns and the jagged sand winds. All who abandon the arduous journeys above for the security of the sewer passageways face the questionable hospitality of the indigenous craftspeople known as The Sewers.
The Sewers are the last remaining people of the Northwestern Landmass who have the skills needed to manufacture clothing. Because it is the only skill that offers them an advantage in the trading networks, they cruelly guard the secrets of their techniques. Without their secrets, the only product they could offer to the markets would be the petrified manure of the ancients. With only that to offer, they would find themselves starved and dying because so few ask for the petrified manure.
The Sewers reserve all garments they make to be sold in the world above them. Because of this, they all live their lives disrobed. The docile underground wind wraps its fingers around their bare bodies, refugees from the desert avert their gaze until they finally become accustomed to uncovered skin, nudity is only interrupted when they dress themselves in newly made clothing to ensure it will fit similar bodies in the dusty world above.
The Sewers’ utilize their nudism to distinguish themselves from the refugees whose bodies are veiled by clothing. Although those who are clothed are not treated poorly, they are excluded from greater sewer events. They are not invited to the occasional dinners afforded to The Sewers by their monopoly on skills of clothing production, but they are treated to the leftovers from these feasts.
The Sewers are kind enough to allow outsiders to participate in their industry, too. For a long period of time before they are truly considered part of the sewer community, the outsiders work as liaisons to the desert markets. They bring the clothing up and the traded goods down in exchange for gradual acceptance - plus, they are compensated for their labor with popular currencies and necessary comforts.
Eventually, some outsiders become Sewers and are offered the privilege of learning the skills hoarded by underground dwellers since the beginning of this age. There have been attempts by desert travelers to infiltrate the indigenous sewer communities by stripping their rags from their bodies and entering the tunnels while pretending to already be Sewers. The Sewers, having exceptional eyes for details, are able to distinguish a dust dweller’s skin from their own. With exposure to the desert, patches of skin are rugged with scars that do not occur in the sewers. If The Sewers discover intent to steal their secrets, the former potential thief is quickly tied and brought to an empty corridor that is strictly used for immolation. Afterwards, the body is transported to a waste corner where it is left to decay.
This brutality towards thieves is the only violence found in the sewers. There is no other place that provides the same asylum from barbarism. Above, even the air is savage. Below, the world is gentle enough for nakedness to be commonplace and for inhabitants to be so untroubled by their surroundings that they are able to socialize without irritation piercing through their interactions. Couriers, wealthy travelers, and even the Dust Raiders rest in the company of Sewers - to escape the suns, to rest without worry of Horrible Centipedes emerging from the sands, and to disrobe and refresh in gentle air.
