Gorgers are the Ogres who committed a terrible crime of being born without a paunch. In the Ogre society, these individuals are thrown down the warpstone labyrinths, which exist beneath all Ogre tribal caves. In there, the warpstone degenerates them into ravenous beasts with powerful talons and enormous maws, that are even more dominated by eating then the regular Ogres.
If there is a nearby battle, they might come out to feast on the Ogres enemies. If they do so, they are an important threat, for they are even stronger and more resilient then the regular Ogres, with talons that can rend anyone and anything in half, regardless of armour or resilience. They are also completely fearless and thus will not leave the battlefield until they are either slain or they run out of snacks.
