The Inlam Stream originates in the east from Lake Altalith, flows deep into The Fault dividing the city in two along its entire length, and then ends its frenzied course in the west with a Great Cascade that plunges into the Faultbottom Gorges of Vorn. The gradient of the torrent is low, but its banks rise increasingly rapidly, reaching a height of 900 meters at the end of The High Terrace. Its water level varies depending on the rainfall and the melting of the snow covering the surrounding mountains, as well as certain more mysterious circumstances. Five bridges span it, each acting as a bottleneck for the movement of goods and inhabitants.

The Inlam is a major site for the spirituality of the city, as even though it has long served as an open sewer and a place for ritual burials, the Great Dryness, when decreed by the God-King, offers it a new lease of life. Similarly, the Toracles, a special caste of diviners who read the future in the meanderings of the torrent, have now gained a good reputation thanks to their predictions.
