At first there was silence.

People died, but there was no outcry. The bodies rested in noiseless repose in tower habitation spires; in the prayer rooms of great monasteries; in gutters by the sides of streets. The deaths went unnoticed. This was a world that saw ten million new pilgrims each month—it was no stranger to off-worlders making planetfall only to die soon after.

The shrineworld of Kathur, named for the saint himself, was a beacon of faith and hope for the people of Scarus Sector. Faith flared or withered for those who came to tread the holy soil of this blessed world, seeking affirmation for lives lived without meaning. Hope flowered or died for those who landed here seeking to touch the relics of a long-dead saint and be healed of injury or illness.

When people began to die there was no planet-wide panic, no ringing sirens wailing across cities, and no distress calls to nearby worlds, crying of a devastating disease. The sickness spread, tearing through the population, but to those who watched for such things, it was just a spike in the numbers. These things happened from time to time.

A plague brought from off-world, the world’s leaders said. Faith will scourge the taint from the righteous and pure.

No warnings. No panic.

Silence.

The silence did not last long.

At the dawn of the outbreak’s second week, there were too many dead for the funeral priests to haul into the consecrated incinerators, and the Ecclesiarchy governors realised their planet was suffering no natural plague. The death toll was catastrophic, and the Kathurite acolytes traditionally tasked with funerary rites walked the streets in gangs, losing the battle to do their simple duty.

The initial astropathic cries for help reached out from Kathur. Several hundred psykers worldwide screamed their pleas into the warp, begging for assistance. Imperial forces in the sector responded to the cries for aid in impressive time: Scarus was forever the Archenemy’s ripest target, and the Emperor’s servants never relaxed their vigilance here. Fleets of ships powered up their engines and broke into the warp, chasing the source of the psychic screams like bloodhounds pursuing the scent of prey.

The stream of comm-channel messages and psychic transmissions from Kathur told of a plague without end, of millions already dead, of a planet dying.

The Imperium was no stranger to the Curse of Unbelief. Even now, the plague wracked dozens of worlds across Segmentum Obscuras—but Kathur was the anomaly, the one world that broke the pattern of infection. The other infected worlds stood on the rim of the Warmaster’s Black Crusade. Kathur, however, was far from the Great Eye and the systems drowning in the tides of battle.

All this death made no sense. There was no spaceship of the Archenemy to spread the taint, no touch of heresy detected among the populace, and no sign of Chaos in the planet’s rule.

But it was the Curse.

The Curse of Unbelief ripped across the shrineworld now, taking those who lacked true faith in the God-Emperor. It rotted flesh and turned organs putrescent while the victims still lived. Many turned to suicide rather than decay in agony. Riots broke out over the planet. Funeral pyres burned endlessly, the streams of black smoke choking the sky around the largest cathedral-cities.

The Adeptus hierarchs receiving the first wave of communications from Kathur ordered the planet cut off from the Imperium at the first signs of the Curse of Unbelief. Assembled in the heavens above the doomed world, a mighty fleet coalesced over the course of several days. They did not come to save the people—they came only to stop the population evacuating. The taint, the fleet-captains knew, must never be spread. On the command decks of Imperial Navy vessels stationed in high orbit, stern-faced inquisitors oversaw the blockade’s management.

No vaccine had ever been found to ease the sufferings of the afflicted. In the words of Inquisitor Caius, as he stood on the bridge of the Gothic-class vessel In His Name, “We consign these souls to oblivion, for mercy now would damn us all.”

The blockade of Imperial Navy vessels hung in the reaches above Kathur, enforcing the quarantine with lethal vigour. Thousands of the Emperor’s citizens died under the anger of Imperial guns as the blockade vessels fired on any ship fleeing the planet. It wasn’t long before the attempts ceased. The people on the surface were either too ill to make the journey, or already dead.

Bizarrely, pilgrims sought to make planetfall, still wishing to walk among the cathedral-cities of the saint’s world and receive the blessing of Saint Kathur. Any attempts by pilgrim vessels to reach the surface were deterred by stern threats and the weapons batteries of Cobra-class destroyers. Such warnings, a barefaced presentation of the Emperor’s might, were enough for most ships. A single vessel had been filled with souls pious enough to run the blockade. This ship, a wallowing barge little more than a cargo hauler and packed with three hundred pilgrims, ultimately did make it down to the surface of Kathur. What remained of the ship after its brief encounter with Imperial Fury fighters flamed through the atmosphere and crashed into the western ocean.

Inquisitor Bastian Caius of the Ordo Sepulturum stayed in vox-contact with the Enforcer Marshal of Kathur, a man by the name of Bannecheck, until the very end of Imperial control. The commander of the planet’s Enforcers remained in touch with the inquisitor for seventeen days, describing the scenes of carnage and plague ravaging the surface as his men tried to retain order. Every word was recorded. Each syllable of his rhythmic cant, distorted as it was by vox interference. Through this crackling monotone, Caius learned of the erosion and breakdown of Imperial rule.

On the third day of contact, the marshal reported cults rising among the dwindling Kathur Planetary Defence Force, and of cultists within being spared the curse’s death. The Dictate Imperialis was broken, the Emperor’s Law abandoned. By this time, the global law enforcement force was already effectively destroyed. It fell to the elite Enforcers to take to the streets, slaughtering cultists in a series of brutal raids on hidden strongholds.

Despite initial successes, they were doomed to fail.

On the sixth day, chanting rose from temples across the planet—no longer in praise of the Emperor, but now pleading to the Ruinous Powers for mercy. Control across the planet was under threat, with the capital city of Solthane standing out as the final bastion of Imperial order. The Enforcers entered the cathedral districts of Solthane in unprecedented force, leading the shattered remains of still-loyal PDF and the still-living law enforcement officers. Their objective was to quell the rising cults across the planet in a decisive and damning half-week of fighting.

Bannecheck reported losses among his forces of ninety-three per cent on the morning of the ninth day. The cults’ numbers were far greater than had been initially surmised. Those that were not already well-armed by the PDF defectors overcame Enforcer assault teams by sheer weight of numbers. The marshal produced evidence, in both audio and pict form, of his men dragged down and eaten by plague victims in some districts, and falling under fire from hordes of cultists in others.

Caius looked at other grey, blurry picts beamed up from the surface by Bannecheck. Here an Enforcer team’s Repressor tank flamed in the street; there a horde of plague victims surrounded a monastery filled with dying citizens.
