Flarg

Flarg is the primeval God of the Hill Giants.  He was the first to decide to create a lesser being.  He chose to create the Orcs.  The Orcs were then sent out into the world to hunt and gather animals for Flarg and his Hill Giants to gorge on.  The Orcs were feeding him and the giants daily, and they were made to increase quickly so that more food could be gathered as Flarg's appetite is boundless.
He is a faithless god, as his concern is only for himself and his hunger.  But those he claims for his are subject to his punishment if he finds them lax in his feeding.  
As with most gods he retreated to the planes at the end of the Age of Giants and Dragons.
