At the end of the campaign described here, the characters destroyed a sinister force known as The Iron House. However, a previous group (run in Australia) played in a campaign set in 1872 where they worked for an organization known as The Iron House, in the interests of the Queen. In an early session, they were dispatched to the 1872 Manchester Cornucopia of Arms and Armour, where the latest battlefield technology would be on display and one of the inventors was planning on defecting from Prussia to Great Britain. The characters’ task was to identify agents who might interfere with the defection, and if necessary kill them. This meant spending two days in the grounds of the Cornucopia posing as merchants, and so they were able to witness displays of a couple of the latest developments in infernal weaponry. Here are three examples of the kinds of things they saw.

The Steam Tank: In the age of the Essential Compromise, steam engines can be rendered very small through infernal summoning and materials, though the process is very expensive. A steam engine consists of two chambers separated by a turbine; in one chamber an imp boils water to impossibly high temperatures, which then passes through to a turbine before entering the second chamber, where it is condensed back to water and pressurized by a second imp. This imp forces it back through another turbine to the first imp. Thus a perpetual motion machine is produced based entirely on steam and the ceaseless labours of two very unhappy imps. The latest infernal materials prevent heat or cold leaking between the chambers or from the engine into its environment, so the small engine can be mounted in the middle of a small room or vehicle – though heaven help the occupants in the rare occasions that the engine bursts and the imps escape their confinement.

This engine has been put to its ultimate use in the development of the Steam Tank, a wheeled armoured vehicle crewed by two intrepid soldiers, one who directs its movement and one who fires a small cannon mounted atop the vehicle. In early models the cannon was a static mortar, and the vehicle little more than mobile artillery; but realizing the cost of the engine was such a great part of the whole, the Prussian Steamworks expanded its power and used it to drive a mobile turret, which now contains the latest in heavy infernal weaponry – an infernal cannon, or a nest of field rods of some kind. Rumour has it that a larger version is in development, that carries prisoners of war (or just prisoners) who feed an autonomous sentinel cannon from within cramped cells on one side of the vehicle, though the experimental version is said to have been simply a tumbrel dragged behind the tank itself.

This tank is being used only by the Prussian military but – perhaps as a political symbol of Prussia’s growing military might – one and one only has been sent to the Manchester Cornucopia for demonstration purposes[1]. Invulnerable to infantry weapons and too mobile for artillery, it forebodes a revolution in cavalry warfare.

The Reanimator Field Rod: The ultimate in infernal field rods, the Reanimator Field Rod carries this line of weapons to its ultimate conclusion. Usually carried into battle by a priest or wizard, the rod fires a cone-shaped blast of dimly visible grey-green light, which animates any fresh corpse in its area of effect. This corpse is then under the control of the Rod’s wielder, who must himself be attuned to the rod through a specialist ritual. The French army is said to have established a few squads of their infamous battle-priests armed exclusively with these rods, and will send them to the rear of the first wave of soldiers to enter the fray. Though these soldiers may be cut down or horribly decimated, their opponents will find themselves then facing the dread prospect of fighting again not only those they just killed, but those of their friends and allies who were also sacrificed in the melee. Every defeat of the enemy is redoubled by these priests, and every loss partially reversed. Who can doubt the terrible effect of this on the morale of those who fight, and on the judgment of those who lead[2]?

Persian Anti-personnel bombs: aka Turkish Delights, are a nasty little invention of the Ottoman Empire, which has been developing considerable skills in pacifying aggressive populations during the food riots of the past two years. These bombs are barely large enough to significantly injure an armoured man, being roughly marble sized. Presented by the handful in a special magical bag, they are completely inert in the bag, so a Turkish soldier has no risk of blowing his chest out when he dives for cover from an Anatolian death-archer. However, once out of the bag they are immediately primed, and explode after three sharp impacts, such as occur when they are thrown down steps into a basement, bounced along a corridor, or skipped across the surface of a fountain. The resulting explosion is concussive, but will easily kill or seriously injure an unarmoured rebel (or his family, if they are sheltering in the basement with him). Such devices have obvious uses in England, given the recent riots over corn laws and the other unrest being fomented by capricious foreign powers. They are also useful in ship-to-ship warfare.

fn1: During the adventure this tank was stolen by the defector’s Chinese lover, and they finished the adventure chasing it through the streets of Manchester while Prussian agents attacked them and tried to capture it and the defector it held. Much of central Manchester was laid waste in the process.

fn2: Not to mention the judgment that will be placed upon those who use such a weapon…
