The brute and savage Ork race infests the galaxy like a plague. Mankind has fought against this greenskinned scourge since the very first steps taken out into the stars. An entire civilisation that thrives upon conflict and war, the Ork race is divided into many different (and fractious) tribes, klans and hordes. Each fight amongst themselves for the most part, but occasionally a particularly strong warboss will unite his lesser kind into a Waaagh!; an all but unstoppable tide of brutal violence.
