An Inheritance of Stars
The Orks, also called Greenskins, are a savage, warlike, green-skinned race of humanoids who are spread all across the Milky Way Galaxy. They are seen by their enemies (pretty much everyone else in the galaxy) as savage, warlike, and crude, but they are the most successful species in the whole galaxy, outnumbering possibly every other intelligent race, even Mankind (with the very plausible exception of the Tyranids, who are split between thousands of subspecies genetically engineered for specific purposes). However, this massive population of Orks is split into hundreds of tiny empires, often warring between themselves. It has been speculated that were the Orks ever to unite as a single racial entity, they would undoubtedly crush any opposition that would dare to stand against such a tsunami of green muscle. Luckily, the Orks enjoy killing each other every bit as much as they savour shedding the blood of the galaxy’s other peoples.
Though not overly intelligent, Orks seem to have an instinctive grasp of technology. Their weapons are crude but effective, as are their vehicles and ships. When Orks take to the stars they often travel on ships which have been captured in battle, and then modified by the mekboyz. War hulks are bashed together from scrap to produce further transports for the horde, and occasional they may infest a Space Hulk to move from world to world or even hollow out asteroids and create the massive spaceborne Ork fortresses known as Ork Roks.
