Silk Market Cistern

The Silk Market Cistern is a public water supply in Torrune's High City. It is located in the eastern neighborhood of the Silk-Seller's Quarter near the foot of Okhtar's Hill, and fed by a many-stepped rill channel running down the side of that hill. The water itself ultimately comes from the spring of the Carnelian Baths atop Hart's Hill; it is carried from there across the Tirasval by the Greenstone Span, where some is diverted to the archon's palace cisterns and the rest flows down to this cistern and the Pool of Parth. 
The cistern is located several blocks away from the edge of the actual Silk Market for which it is named.
