Orks - Ork Kultur: From pirate enclaves to system-spanning Ork Empires, Ork holdings are as varied as they are steeped in violence. When they invade a planet or a star system, Greenskins bring with them a belligerent ecosystem that overwhelms each conquered world as surely as the Orks themselves crush its defenders.Greenskin society and ecology is so robust that it can exist almost anywhere, which is why their settlements have been found scattered to the furthest corners of the galaxy.The Imperium has encountered Orks and their kind living -- even prospering -- in such extreme environments as toxic Death Worlds, newborn planets still heaving with volcanic activity, or the depressurised carcasses of abandoned orbital platforms. Ork hordes have been found inhabiting drifting ice floes, or infesting irradiated asteroid fields perilously close to active stars.They have been discovered amid corrosive chemical swamps, on lightless nightmare worlds seething with horrific predators, even in the bombed-out remains of planets subjected to Exterminatus. It is rumoured amid the Imperium's Rogue Traders that there are even Ork enclaves hidden within the Eye of Terror itself, though most dismiss this as the ravings of madmen.No matter where they are encountered or in what numbers, the Greenskins are a deadly threat that will multiply exponentially if left unchecked. In a matter of solar weeks what began as a small raiding party can swell -- as if by some arcane alchemy -- into a roiling, anarchic horde bent upon war and destruction. The other starfaring species of the galaxy have many theories regarding how the Orks' numbers increase so quickly. These range from spontaneous physical division to the release of windblown spores after death.The notorious "Vandermeist Theorem" even claims that the Greenskins inhabit an alternative pocket of reality and simply fall through, fully formed, wherever others of their kind are already at war.While many of these wild suggestions are patently ridiculous, it is certainly the case that where one Ork is encountered, more will never be far away.When combined with their relentlessly warlike nature, and tendency to grow larger and more powerful with every battle they survive, it is easy to see how rampaging Orks can quickly overwhelm a planet's defences.A ragged band of Orks allowed to escape the wreckage of their spacecraft and disappear into an Imperial city's underhive will return within solar weeks as a horde of murderous savages, sweeping all before them in their desire for conquest. Those they do not kill will be enslaved, and that which they do not destroy will be looted.Before long, another world will be conquered by the Orks, its cities reduced to ruins and its populace toiling in chains as slaves for their brutal Greenskin overlords.Those who have studied Ork settlements (and survived) have observed that Ork civilisation is hierarchical in the extreme. The life of a Greenskin is determined not by rank or birth, but by size and savagery.The largest Orks push around their smaller brethren, who in turn bully the diminutive slave-race known as the Gretchin into doing their bidding. Smaller still are the Snotlings, tiny and simple-minded creatures with little use beyond fungus tending or fetching and carrying.The Orkoid sub-races have a symbiotic relationship of sorts; the smaller Greenskins perform menial tasks for their Ork overseers in exchange for a measure of protection. The Ork language literally has no word for "diplomacy"; they solve almost all of their disputes by fighting.Indeed, many other intelligent species believe that violence itself is a language amongst the Orks, since they use pain and brutality to get their points across to each other. Orks are not very intelligent or clever, and they even label the use of strategy and fleeing from battle as simply "un-Orky."
