Mobgnomes were medium-sized beings that resembled a cross between goblins and trolls. It is unknown if there were any more varieties of Gnome. They were usually nimble and quick and employed as deckhands on sky pirate ships. Also they made up about half of the Sanctaphrax basket-pulling servicemen along with the 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 in the Slave market.
