When you live at the bottom, the only thing you have is to look up. If you're lucky you can see the lights of the great towers and the stars. If you're like most people, you just look at concrete. But the stars and lights are still up there.
These well crafted Dwarventi stairs lead down into one of the three main passages of Undertown. The underfolk have cleverly made it look like a short surface streets. Some of the branching passages look like streets as well, but it is all just a facade, soon they become more mine or hall like. The streets are “lit” (dimly by any topsider’s opinion) by mage lights and a few ancient amber Dwarventi Lights.
For all the aquaducts coming into the city, there munt be a place for the water to leave. Thus, many years ago, the Blackwater Tunnels were commissioned to carry sewage away from the city buildings.
Saril had a dream. To open a library in the windswept wastes of Naarish, so that the people of the many villages and towns spread over the hundreds of leagues of desert could discover the joys of his books. For a whole year he kept his library open, but alas, almost no one came.
That is when Saril came up with his new idea. If people didn't travel to read his books, he would travel to them! Saril closed his library, hired a team of twelve camels, loaded up the beasts with all of his books and proceeded to invent the first nomadic library.
Now children and adults alike, looked forward to hearing the bells of Saril's camels as he entered their villages, as he tirelessly traversed the deserts in a long circuitous route, visiting every village and town he came across, in turn. It came to pas that Saril's traveling library came to some fame, and that is how the folk of Naarish became literate.
A word of warning though. Naarish has only six thousand volumes. He deals with those that lose or steal his tomes quite "harshly", by bypassing the town or village which was responsible for losing one of his books for that calendar year.
