Coomb Imago

I made these sketches to give me a clearer idea of the setting of the scene in The Chosen in which Carnelian comes by bone boat to Coomb Imago to visit Jaspar. For scale, Carnelian is shown standing before the steps. The first sketch shows the approach to the coomb, a cleft in the Sacred Wall: “They rounded a promontory into a deep coomb bay. An outcrop swung past the starboard bow and a view […]

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 […]


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 […]

Lower Palaces

This map shows the lower palaces of House Suth built on the curl of land forming the floor of a semi-circular coomb or valley that is open to the Skymere along its south-eastern edge. An idea of how large this domain is can be gleaned by comparing it with the ‘nose’ like structure, shown in the bottom right hand corner, that is the Hold drawn to the same scale. Much of the available land in […]

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 […]
