Chapter: Tower Sun Ninety-Three

Information relevant to the 4th chapter of The Mirror Breaks

Sapient capsules
an open Sapient capsule

A sapient capsule is shown set vertically and open. Within it a Sapient ‘stands’ with his homunculus between his legs. Both are ‘stowed’ for transit—held in place by many leather straps. Note the hollow they are in is padded to absorb shocks as the capsule is moved from one place to another. The Sapient is wearing a standard sapient mask to which breathing tubes are connected (coming into the capsule from the right). Note the rectangular repositories for the elixir ‘pearls’

Makar and the watchtowers of the Great South Road
Makar at the top of its pass

The map above shows the location of Makar, near the southern edge of the Guarded Land, and at the head of a canyon system that runs down to the Leper Valleys. It is the terminus of the Great South Road from Osrakum

a map of the city of Makar

The second map shows Makar in some detail. The city proper is the curving red element that is shaped a little like the body of a peeled prawn. This part is ancient and is a sort of peninsular surrounded by canyons that are the beginning of the system of canyons running down to the Leper Valleys. Alongside the Old City, running down its western side, is a much narrower peninsular upon which is built the legionary fortress of Makar. Makar’s ‘red eye’ is its cothon

The large yellow-green swelling to the north of the city is an area dense with hovels, within a boundary ditch. The indigo lines show the raised roads of the Ringwall and the Great South Road. Three watch-towers—shown as violet spots—lie on or near the junction of these roads. The most northern stands at the junction. The other, nearby, stands guard over a gate that gives access to the Pass and, thus, controls the route down to the Leper Valleys. The third guard the gate of the legionary fortress. When Carnelian enters the city from the north, he passes each of these towers in turn

Note the road that runs through the fortress from its entrance by the watchtower all the way to the ‘island’ at its southern tip—that is reached by means of another ‘island’ (the sanctum) and two bridges. This last tear drop, looking down the Pass, is the tower of the Legate of Makar

the sanctum and the tower of the legate of Makar

The third diagram is a sketch showing the most southern part of the legionary fortress. The first ‘island’ is the sanctum and is divided into domains for the use of the Masters who command the dragons of the legion and for their households. The most southern ‘island’ of all is where are located the halls of the Legate of Makar.

Osidian’s camp around Tower Sun Ninety-Three
Osidian’s camp around Watchtower Sun-Ninety-Three

This is a rough sketch of Osidian’s military camp around Watch-Tower Sun-Ninety-Three—but it could be the camp formed around any watchtower

The raised-road crosses the picture from south to north. The pink areas show the extent of the camp. The circular feature is the sinkhole at Sun-Ninety-Three from which all water is drawn. At the centre is the watchtower itself. Note the break in the leftway—the narrow ‘tramlines’ running up the right of the road—that allows movement across the road between the halves of the camp

The darker ovals are dragons forming a wall around the tower. The beast alongside the leftway is Heart-of-Thunder. Note the ramp near him leading off the road

watchtowers

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

top storey and watchtower roof and ribs
top storey and watchtower roof and ribs

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

barracks storeys for watchtower garrison

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

watchtower entry from the leftway

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.

two of a watchtower’s stable levels

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
