O . . .
A minor spacefaring race. Using crudely engineered jump ships, stolen and hijacked vessels, space hulks, or any other form of transport they find, these beings plague civilized space. They typically seek to gain a foothold on a world and spread from there through violent conquest and rapid biogenesis reproduction. In several worst case scenarios, orks have subjugated entire worlds, turning the world’s people into slaves who toil till death building new ships and weapons for further conquest. Orks are unrecognized in the eyes of the emperor.
