The term Krork (see Old Ones) redirects here but is not mentioned in the article. Can anyone provide information on this alternate name? —Archlords 05:31, 8 October 2007 (CEST)

It is the name the Old Ones and the C'tan stargods (Deciever) use for the Orks. The Old Ones created them to save their remaining bases but it was too little too late. There is short-story "Deus est Machina" in which the Deceiver says that he is very admired that the Krork are everywhere in the galaxy. Irulan 13:35, 8 October 2007 (CEST)
