Coomb Suth

Coombs are valleys eroded into the inner face of the Sacred Wall. These are the many indentations that can be seen in the model of Osrakum. The Great and the Lesser Chosen have their palaces and gardens built into these coombs. Only the highest Houses of the Great possess a whole coomb to themselves. Coomb Suth is Carnelian’s ancestral home. The map shows the palaces set into the floor of the coomb. Above, carved high […]

Entering the Canyon

A view of the mouth of the Canyon of the Three Gates as seen from the Wheel, showing the flanking colossi carved from the rock of the Sacred Wall itself. For scale, a mass of human figures is shown passing between the colossi. Having entered the Canyon, it is necessary to pass the Green, Blood and Black Gates before gaining entry into the crater of Osrakum itself.


The Eyries are summer palaces built high in the Sacred Wall where the Suth can escape the summer heat. It consists of a series of ‘stratum’ set one above the other, and connected by stairs [shown as wiggly lines] cut into the rock face. Each stratum is made up of numerous caverns carved into the Sacred Wall. Water is provided by cisterns—cut even higher up—or lifted laboriously by slaves from the Skymere. The Suth Eyries […]


Welcome to Osrakum. In this section maps and diagrams are presented in a sequence mirroring that of the narrative of The Chosen. Osrakum is a volcanic crater containing the Skymere and, in the midst of this lake, the Isle. On the Isle is the smaller crater containing the Plain of Thrones and, beyond that, the Labyrinth. The Yden forms the greater part of the Isle. From the heart of this rises the Pillar of Heaven, […]

Osrakum (model)

I made this model to better understand the complex landform that resulted from the collaboration with Professor Ben Harte—alas, it was destroyed in a house fire. The crater of Osrakum contains the Skymere lake and has the Isle at its centre. On this island are the smaller cone and crater, that contains the Plain of Thrones, the Labyrinth, the Pillar of Heaven and the Forbidden Garden of the Yden. The edge of the large, almost […]

Views on Entering the Wheel

I produced these diagrams to better visualize Carnelian’s entry into the Wheel in The Masters (The Chosen in the First Edition). They are indicative of the exhaustive preparatory work that I used to do and that was strongly influenced by my working method in my—then recent—previous career as a designer of computer games. Each diagram is an accurate perspective drawing. The first diagram is what Carnelian can see as he approaches the gatehouses of the […]
