Rogue Trader Vendet Corbin is ordered by the Lord Regent to deliver a vital package. Hunted by assassins and trapped in Ultramar, he must survive - or doom the realm.
Description:
Rogue Trader Vendet Corbin of House Vonice has led his dynasty for many years, when he is personally conscripted by the Lord Regent to transport a critically important package. The destination is secret, and the stakes are immense. Along the way, Corbin becomes the target of numerous assassins, forcing him to seek armed escorts. The reasons for the attempts on his life are uncertain: some believe they stem from his connections to criminal organizations, while others argue his flexible, non-dogmatic approach places him at odds with the Inquisition. It may be both—or something far more dangerous tied to the contents of the package itself. Whatever the truth, Corbin must survive long enough to escape Ultramar and complete the delivery. Failure is not an option, as the fate of Ultramar itself hangs in the balance.
500 Worlds of Ultramar: Alliance Under the Treason
Summary:
A forced Imperium-Aeldari alliance strikes the hospital-world Biham in Ultramar to stop a rising Chaos cult. Trust is absent, but survival demands cooperation before devastation follows.
Description:
Alliance Under the Treason follows a grim, necessity-driven alliance between the Imperium of Man and the Aeldari Craftworld Beul Wok’na. A newly emerging Chaos cult, calling itself the Inheritors, has escalated from minor, covert actions into increasingly bold and destabilizing attacks. Their pattern draws both factions to the planet Biham, a rare and irreplaceable hospital-world on the edge of Ultramar. One of only three such worlds in the entire Ultramar system, Biham is essential to sustaining Imperial forces and civilian populations alike. Its fall would be catastrophic. The threat deepens when evidence reveals the cult has also targeted Aeldari Craftworlds, implying motives that endanger both species. This alliance is not born of trust or diplomacy, but of survival, as ancient enemies are forced to stand together against a shared, growing darkness.
500 Worlds of Ultramar: Behind the Aquila's Shadow
Summary:
An Imperial stronghold in Ultramar has fallen silent behind enemy lines. Disguised, outgunned, and expendable, you're sent in to sabotage, extract a prisoner, and escape - if escape is even possible.
Description:
A loyal Imperial fortress has gone dark. Official records list it as destroyed, yet recent astropathic echoes suggest otherwise. Vox traffic, encrypted signals, and irregular troop movements indicate the installation is still active—now operating under unknown control.
You are deployed covertly, inserted far behind enemy lines under false identities and incomplete intelligence. Your objectives are simple on paper: infiltrate the stronghold, identify who or what now controls it, extract a high-value prisoner held within, and cripple the facility before it can threaten nearby Ultramar systems. Nothing about this mission is expected to go cleanly.
Good luck. The Emperor protects...sometimes."
Carnadeuos is a lush Imperial pleasure world, but beneath the Corv Desert lies an unrecorded Chaos temple. A dead priest fused to its gate and warring cults signal a growing threat.
Description:
On the surface, it remains a symbol of Imperial luxury and stability. Deep within the Corv Desert, the Inquisition has uncovered an ancient Chaos temple—one that appears in no Imperial records or archives. The structure predates all known settlements on the planet. Grafted directly into the temple’s sealed gate is the corpse of a long-dead heretical priest, his body fused with metal etched in blasphemous runes, as though the gate itself consumed him as part of some forgotten rite. Worse still, intelligence reports suggest the presence of two separate Chaos cults, locked in violent conflict over the site. Your mission is to investigate the temple, uncover the truth behind the cult war, and ensure whatever lies buried beneath the sands never threatens Ultramar. May the Emperor protect.
A three-year war on Orion between Imperium, Aeldari, and T'au ends in ruin when Genestealers emerge, forcing bitter enemies into an uneasy alliance to stop extinction.
Description:
On the planet Orion, just beyond the borders of Ultramar, a brutal three-year war has raged between the Imperium, the Aeldari, and the T’au. Each faction believes the world is rightfully theirs: the Imperium seeks glory for the Emperor, the Aeldari claim it as an ancestral home, and the T’au have lived there undisturbed for four centuries. Endless conflict drives all three powers to the brink of annihilation, exhausting armies and shattering defenses. When nothing remains but survivors and ruins, a far greater threat reveals itself—Genestealers rising from beneath the surface, unseen until it is too late. With extinction looming, the remnants of each faction are forced into a desperate alliance. Trust is nonexistent, but one truth binds them together: the Genestealers must not escape Orion, no matter the cost.
500 Worlds of Ultramar: The Lord Regent, the Farseer, and Macragge's Honour
Summary:
After a Necron assault on Bova V, Ultramar burns. You are Aeldari agents tasked with recovering an ancient artifact before the Imperium claims it or the Necrons erase it forever.
Description:
The world of Bova V lies battered in the aftermath of a sudden and devastating assault, its defenses shattered, and Imperial forces stretched thin. For the Imperium, the situation is dire—but that concern is not yours. Your mission is singular and absolute: locate and recover an ancient Aeldari artifact known as Partecion Yess Quas. Long hidden, its presence has been revealed by the chaos of war. If the Imperium secures it, the balance of power may shift in ways no Farseer can fully predict. If the Necrons find it, the artifact may be lost to history—or worse, repurposed. Time is short. Guilliman’s forces tighten their grip on Ultramar, and the legendary Macragge’s Honour casts a long shadow across the region. The artifact must be found and returned to the craftworld at all costs. Failure is not measured in death, but in consequence.
A captured T'au vessel drifts above Ultramar, its interior a mechanized fortress. Your mission is to breach the ship, locate its central map vault, and seize strategic data before it can be purged.
Description:
Long-range scans suggest the ship is less a warship and more a fully mechanized fortress, layered with internal defenses, sealed bulkheads, and autonomous systems designed to repel boarders at every turn. Imperial intelligence believes the vessel contains a hidden map vault—a central command chamber storing strategic star charts, supply routes, and forward-operating data crucial to ongoing T’au expansion efforts. If secured, this information could shift multiple campaigns in Ultramar’s favor. You are deployed via boarding action into the vessel’s interior, where corridors shift, defenses activate without warning, and enemy resistance grows stronger the closer you draw to the vault. The ship itself seems designed to mislead, isolate, and destroy intruders before they ever reach their objective. This is not a mission of conquest, but precision. Find the map room. Secure its data.
