Chapter: Murderous Grief

The first sketch shows Carnelian and Blue standing before the wreck of the Iron House

It has come off the road—the two dragons that pulled it, having tumbled to the ground, one of the wheels of the chariot having buckled as it fell. One of Osidian’s dragons is still on the road, lying where it fell on the other wheel. The standard of the Green God can be seen lying upside down leaning against the road. It is in the space underneath that Carnelian and Blue seek shelter from the rain

The second sketch shows Osidian’s attack coming along the road. The fire from his flamepipes causes the Iron House to swerve off the road

The third sketch shows Carnelian and Blue standing before the wheel of the Iron House that buckled when it came off the road and hit the earth. The boss from its hub lies like a bowl on the ground.

There is also a sketch of the Iron House half off the road that was a precursor to the more detailed sketch above. This kind of ‘storyboarding’ helped me visualize a scene before I wrote it

The diagram above shows side views and a view from above of a standard watchtower. Each such tower stands guard on a gate controlling passage from one province into another through the wall that carries a leftway. Note the drawbridge that carries the leftway over the gateway below

Watchtowers are set at regular intervals along the raised roads of the Guarded Land. These towers and the high road—the leftway—that runs under their gaze, form not only the primary communications systems of the Commonwealth, but also provide the Wise with a ‘sensory grid’ with which they ‘see’ much of what goes on in the Guarded Land. In addition, each tower is garrisoned with enough auxiliaries to defend the gate over which each tower stands guard

The communication system has two distinct aspects. Messages can be carried as sealed despatches at furious speed along the leftway by couriers who obtain fresh aquar at each tower. Couriers, and what they carry, are protected by stringent codicils of the Law-that-must-be-obeyed.

Shorter and more critical messages are jumped from tower to tower by means of the heliographs during the day or, more slowly, by naphtha flares at night

A watchtower is often at the centre of an extensive stopping place, where the throngs travelling on the road below can make camp for the night

Watchtowers play an important part in the Stone Dance, and it was because of this that I felt the need to understand their exteriors and interiors so well

From the summit of a watchtower, six ribs curve up to hold aloft a platform at the centre of which is located a heliograph device. Naphtha, piped up the ribs, burns in flares to transmit signals at night when the heliograph cannot operate. The ribs branch up from either side of a keel beam. At the ends of the keel beam are two of the tower’s four deadman chairs: the other two hang from the upper ends of the middle ribs. Lookouts sitting in these chairs maintain an unsleeping scrutiny of the Guarded Land and the road below. The keel beam is embedded in the superstructure of the tower that consists of a number of floors: those above the level of the leftway are connected by ladders that can be raised by means of counterweights. Those below the level of the leftway are connected by ramps

Note the trapdoor in the roof that gives access down into the uppermost storey. Note also the staples climbing up the rib in the lower left (of the right hand plan) that gives access to a naphtha flare and to the heliograph platform. The left hand diagram shows the upper storey that provides accommodation for the staff of ammonites who operate the heliograph. It is these chambers that Carnelian, his father and the other Masters occupy each night on their journey to Osrakum

This second page of floor plans shows the two storeys that are the barracks of the tower garrison

The third page of floor plans shows the storey of the tower that is level with the leftway. In the upper part of the diagram is a cistern. Corresponding to this—in the lower part of the diagram—is the ramp that leads down into the stables. A portcullis seals the entry from the leftway. Standing before this entrance is a monolith, the purpose of which is to make it impossible to use a battering ram against the portcullis. To the right of the portcullis you might be able to make out the faint sketch of an aquar as seen from above. I put this in so as to be able to more easily imagine what it would be like leading an aquar into this space. A small diagram on the right hand side of this page is a side view showing how the portcullis and its counterweights work. It also includes measurements for the heights of some of the storeys.

The fourth and final page of floor plans shows two of the three stable levels that are linked by ramps to the upper entrance—from the leftway. Various other mechanisms are lodged here that have to do with the operation of the portcullis, etc in the levels above. The lowest level of all is the uppermost diagram. Note that it too has a portcullis and a monolith set facing it. This gives direct access to the main carriageway of the raised road that runs along the foot of the wall carrying the leftway

The City at the Gates is so named because it lies at the gates of Osrakum. Built on land reclaimed from the Gatemarsh, it has at its heart the great market of the Wheel, from which the five raised roads radiate out like spokes across the Guarded Land. The habitations of its almost three million citizens spread out along the causeways that carry the roads with their watchtowers

From the Wheel, the Canyon of the Three Gates leads into the crater of Osrakum
