Gregorn is a Death World in the Cyclopia Sub-Sector of the Askellon Sector, home to tribal but peculiarly well-mannered humans and to a notable Ork outpost that serves as a base for pirate activity throughout the subsector.[1]


Gregorn orbits a yellow star on the edges of Askellon space. It has a formal Imperial tithe rating based around timber and food, but the hostile planetary environments and adverse Warp conditions have kept it isolated from the rest of the sector. As a result, it lacks either a planetary governor or an Adeptus Administratum presence, and no resources have been allocated to tithe collection for millennia.[1a]


Gregorn was once home to an advanced pre-Imperial human civilization, which inhabited fortified holds within the jungle. This culture, referred to as the Iron Kings by their descendants, are said to have worn suits of iron armour taller than trees and to have fought with spears of golden sunlight. The Iron Kings are also believed to have imported alien wildlife from across the galaxy to use as hunting stock.[1b]

The rule of the Iron Kings was brought to an end by the fall of a spaceborne object that carried with it an invading force of Orks. The Iron Kings originally hunted the Greenskins as they would other beasts, but the invaders eventually grew numerous enough to threaten the planet's rulers. The Kings fought the Orks for hundreds of years, but were eventually defeated and overthrown by the aliens, who toppled their forts and destroyed their technology. [1b]

Current conditions

The planet's modern human natives live in a tribal, low-technology culture based around hunter-gatherer groups and tribal kingdoms. This society maintains a number of surprisingly sophisticated practices, including a complex oral tradition centred around the deeds of ancestral heroes and legends of the Iron Lords' age and downfall. Gregorn kings and nobility retain the ability to organize the groups under their influence to work on large-scale projects, which primarily take the form of erecting stone forts and towers in which populations can retreat to avoid dangerous creatures and Ork warbands. Young nobles are expected to prove themselves by hunting dangerous animals in the jungle. The traditional weapon of the Gregornian clans is the three-metre-long nashan spear, which can quickly be strung with gulas-gut to become a longbow and unstrung to turn back into a thrusting weapon.[1c]

The planet is also home to a large society of Orks, which have lived there since the fall of the Iron Lords. The number of Orks varies depending on the size of warbands passing through, dipping as low as a few hundred before surging to much higher quantities. The Orks live primarily along the impact crater marking their original arrival point, which contains a disordered arrangement of ramshackle dwellings, landing strips, and foundries. The Orks are currently dominated by the Blood Axes clan under the leadership of Kaptin Gen'ral Kakkbad the 'Eadbita, who has recently risen in power after absorbing smaller tribes and settlements and allying with local Freebooter crews. Kakkbad does not live on Gregorn permanently, but visits periodically to reestablish his authority, hold court, and hunt the local megafauna.[1d]

Environment and fauna

Gregorn is tropical, humid, and tectonically active. Its continents grind and push against each other, creating high mountain ranges at their meeting points filled with volcanoes and calderas. The constant lava flows bring rich deposits of minerals from deep within the planet, which together with the high temperatures and heavy storms that lash the surface produce dense rainforests hundreds of meters deep that blanket all available land and greedily expand over areas cleared by lava flows.[1a]

The jungles are home to a variety of exotic and dangerous life. The rich vegetation supports immense herbivorous saurians, pachyderms and ungulates, each multiple tonnes in weight, which in turn support large numbers of predators. Local carnivorous fauna includes carnidons, scaly bipeds the size of a heavy tank but which can move through the jungle without disturbing a single twig; mora, flightless birds five times the height of a man, with sharp beaks that can slice a human apart; and packs of ravenous gulas.[1a]
