Arathema's Web

A confusing network of tunnels leading down into the city from the surface above. There are many entrances into this mess of passages some coming in through the Human sewers. It is difficult to navigate these dark ways as they twist in upon themself much like a spiderweb, and only very few beings have ever mapped out the entire web. The drow know their way in and out of the main few passages, but dare not tread far from the known ways unless they absolutely have to, for it is unknown what lives inside of the deeper reaches of them.
