Kalians are grey-skinned humanoids (or more simply, humans) who worship the demon-god Ughiuttu, destroyer and creator of all life. A more moderate sect are distinguished by the colour of their turbans, though the blue and red-turbaned Kalians will disagree which ones are the dangerous heretics, causing much confusion.
The sourcebook describes the manifestation of Ughiuttu's temple, or avatar, that sounds much more like a piece of frighteningly advanced biotechnology and interacts with human biotech (used to make cheap housing blocks) in a physical way.

The author of the original series, Jeffrey Thomas, has been particularly involved with the RPG. I don't think you would often see a sourcebook publishing an original story based on the RPG cover art. This post has been edited by uncle_jimbo on Nov 27 2017, 19:59
