Grimmig is one of three moons orbiting the planet Adrilles. It is the largest of the moons with a equatorial diameter of 3,226 km. It completes an orbit of Adrilles every 15.945 days. With an orbit that never brings it closer than 1.2 million kilometers, Grimmig is also the moon furthest from its planet.

History – Necrons

Like Abfall and Brache, Grimmig was formed as a result of a war between two Necron dynasties millions of years before the Imperium existed. The largest chunk of rock torn from the planet would form the core of what would become the moon Grimmig. Within that core lay a tomb of the Sautekh dynasty and within that tomb lay the dynasty’s leader.

History – Imperium

Grimmig was home to mining operations. Its surface was rich with ore, which was transported back to Adrilles to be processed and used in the northern Forges. The moon had a sizeable defense force as well, but it was ill-prepared for Hive Fleet Leviathan¹. It was engulfed by the Shadow in the Warp² before any signal could be sent. Its silence was the only clue that something was terribly wrong on Grimmig.

Adrilles War

The machinations of the Jager Corps woke the Sautekh dynasty on Adrilles and on Grimmig, which in turn woke the Rubicon Necrons within Abfall. While forces of the Sautekh dynasty were engaged on the planet’s surface, other arms of its might were formed on Grimmig. In fact, some historians aruge that Grimmig was the Sautekh Necrons’ primary base of operations and not the positions of strength established in the volcanic north of Adrilles in the weeks following the Battle of First Contact. (Those same historians claim that the daemons of Khorne ruled the volcanic north.) The Sautekh Necrons certainly used Grimmig as a staging point for operations conducted on Adrilles. Eternity Gates were used to move Necron troops and Necron controlled Tyranids from the surface of Grimmig to Adrilles.

The Space Wolves Strike Cruisers orbitting Adrilles were scanning the moons and came to learn what was occuring on Grimmig. That information lead to the combined operation known as the Assault on Grimmig, which was designed to cripple the Sautekh operations on that moon. The operation failed. For a considerable time afterward, Grimmig was largely ignored by its enemies.

Notable Locations

Tomb of Imotekh – The Tomb of Imotekh the Stormlord became operational when its lord was awoken by the machinations of the Jager Corps Psykers on Adrilles. The Tomb was where a pact was formed between the Sautekh Necrons and the forces of Chaos.

The Lost Tombs – The Cryptek Lay Arteb was tasked by Imotekh the Stormlord to take a sizeable force into the bowels of Grimmig to find Sautekh Tombs that had failed to rise. The Cryptek did find the Tombs, some of which had become home to Tyranids during Hive Fleet Leviathan’s razing of Adrilles and its moon many years earlier. Outnumbered, Lay Arteb returned to the surface and reported to Imotekh. The Stormlord and the Cryptek later returned to the Tombs with the Necron / Tyrnaid artifact obtained during the Battle of First Contact and were able to use its influence to exert control over the Tyranids.

The Refineries – Refineries were abundant on Grimmig during the time of the Imperium before Hive Fleet Leviathan. Many of those refineries– though badly damaged and no longer operational– were still filled with ore and were sitting near or directly on top of vast networks of mines. Many of those mines had filled with volatile gases in the years since the Tyranid scourge. During the Adrilles War, the Jagers, Tau, and Space Wolves attacked Grimmig in a series of a precisely timed assaults designed to set and detonate explosives at various refineries on the moon’s surface. The hope was that the simultaneous surface explosions would ignite the volatile gas filling the mines, causing enough sub-surface disturbances that the Sautekh Tombs (and thus the Sautekh Necrons) would be horribly mauled. The assaults (collectively called The Assault on Grimmig) failed.

Brache is one of three moons orbiting the planet Adrilles. It is the second largest of the moons with a equatorial diameter of 1,527 km. It completes an orbit of Adrilles every 4.518212 days.

History – Necrons

Long before there was Man on Terra³, two Necron dynasties– Sautekh and Rubicon– waged war on Adrilles. Sautekh was victorious and Rubicon exiled. The cost was such that Sautekh entered stasis. The Rubicon Dynasty– led by Trazyn the Infinite– wandered the space between the stars for tens of thousands of years. When Trazyn had gathered to him what he felt was an army strong enough to once again challenge Sautekh, the Rubicon Dynasty returned to the planet Adrilles. There they discovered their foe had gone into stasis. Trazyn’s fury was so great that the planet’s surface was savaged. Great swathes of rock were cast into the void. The orbiting debris eventually coalesced into two moons: Brache and Grimmig. The third moon– the smallest– was created by Trazyn to house his tomb when he and his army went into stasis to await the return of his enemy.

History – Imperium

Its heavily cratered surface, core stability, and inclination relative to its planet and sister moons made Brache an ideal defensive position for the Imperium. This lunar fortress was sustained by an internal liquid-water ocean. That water supply and the underground ecosystem it supported was the result of extensive terraforming during the development of the moon’s defenses.

When the defenses on Grimmig fell silent it was a signal to Brache that the Tyranids had arrived. (It was widely known that Hive Fleet Leviathan¹ was threatening the Imperium.) Brache was quick to act. The defenses of Brache were the first spear thrust at the enemy. Brache’s offensive strategy resulted in the death of millions of Tyranids but the Hive Fleet had millions more to spare. Within months of Grimmig’s fall, Brache was within the Shadow in the Warp² and its surface was teeming with an enemy driven by a hunger without end.

The strength of its defenses and the skill and resolve of its troops was such that the war on Brache was still being waged  weeks after the planet Adrilles had fallen to the Tyranids.

Adrilles War

During the Adrilles War, Grimmig was a hive of Sautekh Necron activity. Abfall was destroyed when Trazyn the Infinite awoke. But Brache remained silent. It is not known if any Sautekh Necrons survived that moon’s cataclysmic beginnings. Due to the extensiveness of the Imperium’s terraforming and the size of the moon’s defenses it seems unlikely that Necron presence would have gone unnoticed. What is for certain is that Brache’s surface is littered with the remains of Tyranids and the forces of the Imperium who stood strong in the face of their enemy’s endless hunger.

The planet Adrilles has an equatorial diameter of 96,456 km. Its orbit around its sun takes 687 days.

History – Necron

Long before Man had crawled from the muck of ancient Terra, the planet Adrilles was home to two Necron dynasties– Rubicon and Sautekh. The rivalry between these two was so great that it eventually erupted into all-out war. This war was so vast and costly that the victorious Sautekh dynasty entered into stasis after its rivals had been defeated and exiled.

The exiled Rubicon Dynasty wandered the stars for tens of thousands of years. During this time, its leader, Trazyn the Infinite, gathered others who shared his ideals and his distrust of his enemy. In time, Trazyn returned to the planet with the intent of once again waging war and wresting control of the planet from his ancient foe. But when he and his forces arrived at the planet he learned that his rival had gone into stasis. Deep below the surface, the enemy slumbered in tombs.

Trazyn’s ire was so great he unleashed the full force of his might. He cracked open all but one of the Tesseract Vaults3 in his army. His hope was that the unbridled fury of Transcendent C’Tan4 would be such that the planet would be annihilated. That did not happen, but the force was great enough to tear great swaths of rock from the surface.

Trazyn knew his enemies were not destroyed. So he too entered stasis. The last of his power was used to assemble a tomb of rock about his forces. He created a small moon from the shattered pieces of his own homeworld. There he would sleep until he felt his rival awaken, at which time Trazyn will wake with the remains of his own host so that he can once again meet his foe in combat.

History – Imperium

Millennia later, the planet Adrilles was settled by the Imperium and would remain a beacon of civilization for centuries until the coming of the Tyranid scourge.

The planet upon which the Adrilles War was eventually fought is one of a hundred worlds abandoned by the Imperium as part of Kryptman’s Gambit1. In an effort to slow the advance of Hive Fleet Leviathan2, Inquisitor Kryptman had hundreds of worlds either evacuated and razed or, if already under attack, abandoned and left to a horrible fate. Adrilles was one of those already being ravaged by the Tyranids of Hive Fleet Leviathan. Local garrisons fought to the last while the planet’s citizens cowered and wondered why the Imperium had abandoned them.

Adrilles War

Magister Militum Frans Ruldolf and the Jager Corps came to the lifeless Adrilles and found it ideal for their experimentation with psychic powers in regards to developing and controlling Tyranids. After years of searching for an ideal location among the worlds abandoned by Kryptman’s Gambit, the Jager Psykers under the guidance of Grand Librarian Hoeth discovered Adrilles because of its unique and powerful psychic emanations. The machinations of the Librarians and Psykers under the command of Magister Militum Frans Ruldolf further amplified this weave of psychic energy– a volatile mix of Tyranid caused Shadow of the Warp, atmospheric anomalies caused by latent C’Tan power dating back to the Rubicon / Sautekh war, and the newly introduced psychic manipulations of Hoeth and his cadre.  This ever-increasing psychic and atmospheric volatility soon awoke the slumbering Sautekh Necrons. When these once victorious Necrons arose soon too did Trazyn and his forces. The seismic upheaval caused by the rising Necron tombs further destabilized the planet and its atmosphere.


What was once a harsh but fertile and prosperous planet within the Imperium was a cracked and barren husk when the Jagers Corps arrived. Scoured clean of all life by the Tyranids, the planet was abandoned by Hive Fleet Leviathan when biomass ran dry. The Tyranids left behind soon died out, decomposing where they lay or, in some cases, returning to the reclamation pools.

Crumbling capillary towers5 still scratch at the sky. Reclamation pools6 bubble, suggesting life waiting to be reborn. In places where great cities of Man once stood now only remains rubble and hollow shells of former architectural glory. Old battlefields are littered with the destroyed machines of the Imperium.

The northern hemisphere is the harshest of environments. All that remains are the volcanoes and vast steam vents that had once powered the great Forges of the Imperium. Channels of lava cut across the black and barren surface. The ground shakes, as if angered by the harsh treatment it has endured. The massive and deep Klendathu Canyons is found in the northern hemisphere, but in a less volatile region where volcanoes fell silent tens of thousands of years earlier.

In the south, the mountains are the highest. The slopes are jagged and steep, rent at times by large chasms, like strokes made from some god’s molten axe.

The east and west hemispheres were once comprised of sizable continents surrounded by seas. The Imperium had been taking everything it could from inside and from below those waters when the Tyranids descended. No water remains. Great seabeds are now exposed rock. What were once underwater trenches are now merely more mountains and canyons.

There is little trace of the Necron dynasties that waged war on the planet long before the Imperium settled its surface. If the Imperium had uncovered Necron artifacts, the information and those artifacts were lost when the Tyranids came.

What is known now is that the Sautekh Necrons retreated into their tombs which either existed below ground or were taken below ground. Many of the Necron tombs were destroyed when Trazyn unleashed his fury upon returning to the planet, but others survived, including the tomb of the dynasty’s leader. That tomb was encased in the great swath of rock that became the planet’s largest moon.

As the remaining Necron tombs became active, they rose to the surface. The Necrons that spilled from the depths started to sweep across the planet, seeking destroyed and damaged tombs and other artifacts of their dynasty.


Hurricane force winds can ravage large areas of Adrilles for months on end. These winds and the loose sand and rock it picks up and hurls are responsible for the erosion of the planet’s devastated surface following Trazyn’s fury. By the time the Imperium arrived, there was little evidence that the moons had once been part of the planet itself.

When the hurricane winds aren’t blowing, Adrilles is still never calm. There is always a strong wind. It can carry with it bitter cold or uncomfortable heat depending upon the season and the hemisphere.


When Magister Militum Frans Ruldolf and the Jager Corps came to this planet, its atmosphere was ravaged not only by hurricane-force winds but also a chaotic mix of Warp and remnants of Shadow in the Warp7. This creates an isolating effect that has kept Jager Corps’ experiments hidden, but it also seems that the Corps’ psychic manipulations are contributing in some way to the chaos of the planet’s atmosphere.

This strange effect did not exist when the Imperium initially settled the planet centures ago. It has been suggested the problem started when Hive Fleet Leviathan arrived and waged war on the planet. Why it persisted after Leviathan abandoned the planet is currently up for debate.

Notable Locations

Klendathu Canyons – The Klendathu Canyons are a vast system of canyons covering 10,256.24 km2 in Adrilles’ northern hemisphere. The north is predominantly volcanic territory high in tectonic activity, but the region covered by the Klendathu Canyons is one of dormant, collapsed calderas and rents as deep as 30 km. During the Adrilles War, the canyons were the site of numerous battles, including three days of viscous fighting between Chaos Daemons and Tyranids. Those battles became known as The Klendathu Three.

The Volcanic North – The northern hemisphere is one of  volcanoes and vast steam vents that had once powered the great Forges of the Imperium. Channels of lava cut across the black and barren surface. The Jagers had established several stations in this region, a place rich with energy that could be harnessed to power Jager operations in the area and beyond. It is also a region in which Tyranid Capillary Towers scratch at the broiling sky. The area was also one in which several Sautekh tombs rose to the surface. Indeed, after The Battle of First Contact the volcanic north was a region that remained firmly in control of the awoken Sautekh Necrons and their daemon allies.

Southern Mountains – The southern, mountainous region saw very little fighting during the Adrilles War relative to other regions of the planet, but it was the one place where the Vlka Fenryka were able to establish a sizable and defensible stronghold.

The Seabeds – The western hemisphere of Adrilles had once been dominated by a vast ocean surrounding a continent fringed by flora choked islands. When the Jagers arrived none of that remained. The islands and the continent were dead, nothing but exposed rock wearing the deep scars of unimaginable violence. The ocean, too, was gone. The seabed was discernible from the rest of the wasteland only because of its altitude. It was in these rocky plains that the Jagers established numerous recon stations and a supply depots. The ancient seabed is also home to the so-called Tyranid Fields, a region on the eastern edges of the western hemisphere where the seabed meets the continental plate. It is in Tyranid Fields where the Jagers established their largest and most successful research stations.
