Feral World

Life on the surface of a Feral World.

A Feral World is the Imperial planetological classification for a Human-settled planet whose population is composed of nomadic hunter-gatherers or members of early agricultural societies. These people possess pre-industrial technology equivalent to Old Earth's Stone Age, Bronze Age or early Iron Age cultures.

Feral Worlds are populated by tribal peoples largely living without the assistance of advanced technology or even agriculture in some cases and the population is usually quite low as a result, ranging from 100,000 to 5,000,000 people.

This may be due to an ancient failed Human colonisation project from the Dark Age of Technology, ingrained religious preferences, cultural choice, harshness of the environment or some other reason.

Feral Worlds, like their Feudal counterparts, will have little direct political or economic interference from the Imperium and will pay only the lowest grades of planetary tithes, their tithe grade usually given as Solutio Tertius. Feral World populations may be aware of the Imperium's existence in some fashion but are unlikely to know much more than something about a large group of distant people living among the stars.

These planets are frequently unsuitable for later Imperial colonisation, either due to the circumstances which drove the natives feral or because the natives themselves actively resist new people settling on their lands.

The people of Feral Worlds can range widely in culture, from Grox-hunting Stone Age tribes of ancestor worshippers who only recognise the Emperor of Mankind in the most rudimentary of ways, to wild-eyed, post-apocalyptic road warriors, fighting endlessly amongst the toxic, sand-strewn ruins of their civilisation.

The harsh conditions which Feral World populations have adapted to make them ideal recruitment sources for the regiments of the Astra Militarum and the Chapters of the Space Marines since they produce more people with experience in war.

Occasionally the inhabitants of Feral Worlds have been pressed into the service of the Astra Militarum when their world lay inside a war zone, and the chosen warriors have been given rudimentary training in the operation of laser or stub-weaponry. It is more common, however, for Feral World natives to be selected for the various Adeptus Astartes recruitment programs.

Like all Imperial worlds, Feral Worlds are ruled over by a planetary governor, although the nature of Feral Worlds makes this position somewhat different from that of the governorship of more advanced planets. The Imperial governor of a Feral World almost always lives apart from the natives, often in a single city inhabited by outsiders or taking residence in orbit on an Imperial void station, only interfering in the world's affairs to keep psyker and mutant "head counts" down.

Religious heresy is also a regular concern on Feral Worlds, especially amongst warrior-cults prone to infiltration by agents of the Blood God Khorne; constant vigilance and regular belief-modification enacted by agents of the Ecclesiarchy are a necessity.

Governors and permanent staff on such worlds are themselves kept under close scrutiny, in an effort to avoid the phenomenon of "going native," especially in situations where the inhabitants' belief systems have been manipulated into casting the governor as a "Star God."

The culture shock associated with interaction with more technologically advanced outsiders is an issue on Feral Worlds. Removing a feral worlder from his planet and exposing him to such things as Warp travel can be disconcerting and even result in madness and other permanent pychological disorders.

A feral worlder within the wider Imperium often retains their superstitious and tribal idiosyncrasies, which may prove to be social hindrances, such as an obsession with the bones of dead comrades or the mixing and regular application of noxious-smelling warpaint. Other habits, such as manic distrust and aversion to psychic "witchcraft" may be seen as actually useful and commonsensical in the Imperium.

Life on a Feral World[]

At first glance, Feral Worlds would appear backward when compared to more technologically advanced worlds in the Imperium. They are indeed trapped in superstition and ignorance, but no less so than the denizens on any Imperial world, and the concept of progress is as unknown here as anywhere else in the Imperium.

The barbaric nature on Feral Worlds is as pronounced as on any other planet, but here it displays a harsh, personal brutality and dispenses with the veneer of higher civilisation found elsewhere. Feral World natives can view weather as signs from the sky-gods, and the remains of ancient devastated civilisations as relics from ancestors who touched godhood before hubris brought them low.

This is no different, however, than a hive city labourer who tills powerful machinery through rote actions and dogmatic chants, or reflexively makes the sign of the Aquila before entering a hab-room for the first time.

Both see the world around them through a thick fog of superstition, not even knowing that there is more to know. To live in the Imperium is to live in ignorance, an awful but blissful experience compared to the horrible truths that Inquisitors know.

Feral Worlds are as important to the Imperium as any of its planets, and each tithes warriors and materials just like any other world. This means that even if the majority of the population are ignorant of the existence of other planets, there is often a ruling elite connected to the Imperium and governing the world for them.

Populations on Feral Worlds are often kept in check by their faith in the Imperial Creed, and the Ecclesiarchy ensures that this is the first step when incorporating such a world into the Imperium.

On many Feral Worlds, the local religions and beliefs have thus been supplanted by faith in the Emperor, and it could be that He is known by different names, such as the "Sky-Father," "Master of Light," or "Star Lord" by the primitive people of the world. Even if a feral worlder knows little of the Imperium, it is doubtless that he has heard tell of the Emperor and has been raised to revere Him as a god.

There is a near-limitless variety of Feral Worlds within the Imperium, each different from the next, often mixing ancient cultures and technological levels in a myriad of combinations. For example, a Feral World could be little more than an alien wilderness of volcanic tundra, where ignorant tribesmen bow down to effigies of the Emperor whom they call the "father-of-lightning." Here they hunt flying-lizards across deserts of ash and dust using weapons of black volcanic glass, until the sky-men call them to serve beyond the world's edge, never to return.

Another world could be covered with complex territories of nomadic tribes scattered across an endless swamp, who wear the bones and skins of great amphibians, and constantly war with each other for survival. Some show the signs of previously advanced civilisations, long since blasted to ruins from war or natural catastrophe.

Man might live in crude caves nested in crashed orbital towers that could predate the Imperium or even be of xenos origin, using spears tipped with fractal metal shavings to fend off beasts mutated from lesser pets.

Feral Worlds are defined only by their limited level of technology, where populations have little choice but to live in a primitive state.

Feral worlders may well learn to accept the appearance of voidships in their skies and mighty armoured warriors in their cities, their people accepting their place in the universe, perhaps even scorning the skymen for their feeble reliance on metal trickery when the test of a true warrior can only be measured in muscle and bone.

Feral worlders might leave their planet, either taken as part of manpower tithes or as part of an Inquisitor's warband, but still retain the primal essence their upbringing provided.
