Rogue Trader - The Hos Dynasty
Orks are a race of brutish, ugly Xenos with an unquenchable thirst for violence. They are a green-skinned blight on the galaxy, constantly spawning, gathering together in huge numbers, and battering through the stars like a bloody fist, looting and destroying all that is in their path. That might is right is an unquestionable and obvious mantra to all Orks and one that they understand in every cell of their being. They constantly fight amongst themselves, and only the strong survive in Ork society. Those who achieve authority over other Orks (‘da Boss’ as they are known to Orks) do so because they have proven that they are the meanest and toughest Orks around.
An average Ork stands as tall as a human but is hunched with muscle and would tower over most humans if he were to stand fully upright. They have long arms that are knotted with slab-like muscle; they have a thick skull set low on their hunched shoulders with a heavy brow and glittering red eyes. Their mouths are filled with jagged fangs that jut out like a feral predator. The physiology of an Ork is such that they are exceptionally hard to kill and can shrug off injuries that would kill a human, and can survive and recover from having limbs severed and crudely reattached later. Orks speak a harsh guttural language that mirrors their physical appearance and blunt outlook on existence.
Though their technology is crude, they are possessed of an innate understanding and affinity with machinery and weapons. This racial knowledge manifests through the abilities of so-called Oddboyz, who possess a strange quirk of understanding or ability that sets them aside from the rest of Orks. Of these the most crucial to the Ork war machine are the Mekboyz who create the weapons, armour, and vehicles used by Orks to do what they do best: kill things. Mekboyz are ingenious but unreliable artisans who are masters of creating ramshackle but fearsome space ships, war machines, and weapons from scrap and salvage. Even if they do not come out exactly how they were intended, these devices are still terrifyingly effective—most of the time.
They are known to exist inside of the Koronus Expanse with a tiny empire in the middle of The Accursed Demesne that once made a great WAAAAGH that stretched even to Port Wander. Though it was eventually beaten back, the Imperial forces could not break the Orkish stronghold and it still festers in the heart of the Expanse, waiting to emerge again.
