Cheog is the king of the Gargoyles and is on of the Stone Gargoyles. He is the final boss in the first episode of Blood: "The Way of All Flesh". He was a high member of the Cabal practically as high as the Chosen.
From the statement "Stone Made King of the Gargoyles" it can be deduced that Cheog and his stone kin where created not born. It is possible that when a flesh and blood Gargoyle king was destroyed The the Gargoyles or their master Tchernobog decided to build the ultimate Gargoyle king. Cheog was created stronger then any gargoyle before and so were his elite legions his fellow gargoyles of stone.

Cheog was very high in the Cabal however he was bellow Tchernobog's Chosen. He despised the ones that were higher in Tchernobog's favor. Especially Caleb, leader of the Chosen. It is possible that Cheog spent much of his time plotting the Chosen's destruction. Cheog got his wish when he was assigned by Tchernobog to commit one of the things he most desired: The Destruction of the Chosen, and the way he was going to be involved would hurt Caleb worst of all.
