Atomics: the forbidden arsenals of the Great Houses

Atomics was the name given throughout the Imperium to the process of nuclear fission and, more specifically, to the nuclear weapons of mass destruction built upon it. Every Great House of the Landsraad maintained its own family atomics, arsenals held in secret and almost never spent, for the Great Convention decreed that the offensive use of atomics was grounds for planetary annihilation. The weapons carried a stigma older than the Imperium itself, born of their devastating employment in the war against the thinking machines, and for millennia they existed chiefly as instruments of deterrence. The most celebrated exception came on Arrakis, where Paul Atreides turned the family atomics of House Atreides against the Shield Wall itself and rode to the throne of the Known Universe through the breach.

A weapon no House dared use#

Atomics occupied a singular place in the arsenal of the Imperium. They were rarely used, and the reluctance was not merely legal. The weapons harbored a pronounced psychological and social stigma, the residue of traumatic historical events that mankind had never allowed itself to forget. That aversion traced back to the devastating use of atomics during the war against the thinking machines, a conflict in which many worlds were scarred by nuclear fire. The most notable of them were Earth, cradle of the species, and Corrin, the last redoubt of the machine evermind Omnius.

Yet the horror of the weapons never persuaded the Houses to give them up. The Great Houses continued to stockpile atomics through the long peace of the Imperium, and the reasoning offered for the practice was notable. The arsenals were kept in the event that humanity ever encountered an alien intelligence that intended to do it harm. Against such an enemy, it was reasoned, no prohibition written by men for men would apply, and the species would need every terrible instrument it possessed.

The Great Convention and the family arsenals#

The prohibition on atomics was enforced by the Great Convention, the universal treaty brokered between the Great Houses, the Spacing Guild, and the Imperium shortly after the destruction of the thinking machines. Among its articles, each of which began with the words "The forms must be obeyed," the Convention prohibited the use of atomics against human targets. The enforcement clause was absolute in its terror. The offensive use of atomics was grounds for planetary annihilation, the combined retribution of the whole Imperium falling upon the world of the offending House.

The result was a balance both stable and strange. Every House Major kept family atomics; no House Major admitted to planning their use. The weapons became heirlooms of deterrence, hidden away and passed down the generations, their existence universally known and their deployment universally unthinkable. When the arsenals did emerge into the light, the occasion marked a rupture in the order of the Imperium itself.

The Butlerian Jihad and the Great Purge#

The atomic trauma at the root of the stigma began with Earth. Shortly before the start of the Butlerian Jihad, all life on humanity's homeworld was destroyed by atomics, and the cradle of the species was left a poisoned ruin. The lesson was not restraint. Over the course of the Jihad the weapons were turned systematically against the enemy, and in the protracted campaign remembered as the Great Purge, atomics destroyed the thinking machines and all biological life on numerous planets, Earth alone excluded from the tally by virtue of having been lost already.

The instruments of the Purge included pulse-atomics, weapons developed by the Army of the Jihad specifically against the gelcircuitry of the machines and held on the shelf within the League worlds for years before their employment. Their use was absolute in its effect. Each time a Synchronized World was liberated, every human slave and Trustee on its surface died alongside the thinking machines being eradicated. The campaign broke the machine empire and led at last to the Battle of Corrin, and it burned the fear of the atom into the species for ten thousand years.

Not every atomic horror of the age was genuine. On the planet Poritrin, during the second slave revolt, a cataclysm commonly attributed to atomics was in truth caused by the interaction of a laser with a Holtzman shield. The distinction mattered little to those who remembered the fire, and the event was counted among the atomic catastrophes of history regardless. The same lethal interaction between lasgun beam and Holtzman field remained a source of pseudo-atomic destruction throughout the Imperial age.

Catastrophes of the Imperial millennia#

The Great Convention did not end the use of atomics; it made each use a scar upon history. In the second millennium AG the renegade House Tantor managed to land on Salusa Secundus with its family atomics and, in a daring raid, bombed the capital of the Imperium. The Salusa Incident set off an ecological catastrophe that damaged the planet's ecosystem beyond repair. A few members of House Corrino survived, among them the young Padishah Emperor Hassik Corrino III, and the Imperial capital had to be moved to Kaitain, where it remained for the rest of the Corrino age.

Millennia later, atomics were used again during the Great Spice War of Shaddam Corrino IV, in the destruction of Korona, an artificially created research moon orbiting the world of House Richese. The Emperor struck the moon after being tipped off by an anonymous letter left by House Harkonnen, whose Baron had lately been blackmailed by the Richesians, and the resulting damage to the planet below was catastrophic. In the same era the fugitive Earl Dominic Vernius contemplated bombing Kaitain itself to repeat the fate of Salusa Secundus, a plan that died with him when, surrounded by Sardaukar at his Arrakis base, he detonated a stone burner and took a large number of the Emperor's soldiers with him.

Muad'Dib and the Shield Wall#

The most consequential use of atomics in the history of the Imperium destroyed no city and killed no man directly. During the Desert War on Arrakis, Paul Atreides, fighting under the Fremen name Muad'Dib, held the family atomics of House Atreides, which his men had managed to retrieve after the Harkonnen attack that destroyed his father. When the Emperor himself landed near Arrakeen, Paul launched his final assault. He used the Atreides atomics to blow a hole in the Shield Wall that protected the capital from the deep desert and its storms, and through the breach the Fremen rode their sandworms into the Battle of Arrakeen, overwhelming the Sardaukar and Harkonnen forces and delivering the throne to House Atreides.

The stroke was as much legal as military. By turning his atomics on the Shield Wall, a feature of the terrain, and not directly upon the opposing forces, Paul circumvented the Great Convention. No human target had been struck, no clause plainly violated, and no House could invoke planetary annihilation against him, which paved the way for his ascension. The maneuver demonstrated what the Houses had always quietly understood, that the Convention's forms could be obeyed in the letter while its purpose was shattered along with the rock.

The stone burner and the letter of the law#

The law's careful definitions produced one further ambiguity, the stone burner. The stone burner was not considered an atomic weapon proper, for it merely ran on atomic fuel, yet it delivered destruction of a comparable order along with a signature horror of its own, radiation that dissolved the eye tissue of every creature within its radius. Stone burners appeared in the wars of Muad'Dib's own empire. During the conquest of Naraj, the defenders activated one such outlawed atomic device, and among its victims the son of the Fremen veteran Farok lost his eyes.

At the end of Paul's reign as Emperor the weapon reached the throne itself. Insurrectionists conspiring against Muad'Dib destroyed part of Arrakeen, and the blast left Paul Atreides permanently blinded, the Emperor who had broken the Shield Wall losing his eyes to the atom's lesser cousin. The event stood among the recorded uses of atomics in Imperial history even though the device fell outside the formal definition, a final demonstration that the boundary between atomics and everything else was a matter of treaty language rather than of fire.

Known kinds of atomics#

The records of the Imperium and of the ages before it named a variety of atomic weapons. The stone burner stood apart, an atomic fueled device excluded from the formal class. Among the atomics proper were counted Big Blasters, Deadly Dusts, the Devastator, City-Killers, fusion bombs, Planet Killers, and the pulse-atomics of the Butlerian Jihad, along with contraband atomics, the general term for illicit devices circulating outside the sanctioned family arsenals. Whatever their form, all shared the same inheritance, the stigma of the machine wars and the shadow of the Great Convention, which together kept the most terrible weapons of mankind buried in the vaults of the Great Houses for ten thousand years.
