Fayrgs are an extinct race of creatures that were likely wiped out during the cataclysmic God Wars. They were crossbred from ogres and ourgs by Bandos. Not much else about them is known. Their remains, Fayrg bones, can be found in the coffins at Jiggig.
Fayrgs were lieutenants to Ourgs. They were "damage control" handling serious situations in the midst of battle while their Ourg masters dealt with the battle as a whole. They have large mouths for bellowing orders. They are half way between Orks and Ourgs in height.
