Mobgnomes were medium-sized beings that resembled a cross between goblins and trolls. It is unknown if there were any more varieties of gnome. Mobgnomes were usually nimble and quick and employed as deckhands on sky pirate ships. They made up about half of the Sanctaphrax basket-pulling servicemen along with gnokgoblins. In the Rook Trilogy, many of their number in Undertown were slavers. One of them was Mindip, who caught Rook himself as a slave and sold him on the Slave Market.
