‘That is the largest ork I’ve ever seen,’ Savona murmured, staring up at a towering, twelve-metre-tall monstrosity that loomed in a nearby nook. ‘And his weaponry…’ The frozen creature wore a crude exoskeleton far in advance of anything the orks now might conceive of. Indeed, from his initial examination, Fabius suspected that it might be in advance of his own battleplate.
‘A krork,’ he murmured. ‘One of the first orks. I read about them in the aeldari texts. I have long theorized that the orks are a form of organic weapons system – a rogue biological agent, unleashed during some ancient apocalyptic conflict. There’s too much about their internal workings that seems designed, rather than evolved.’
