Each Ironclad has numerous turrets containing enormous guns which can swivel to come to bear on approaching targets. Each Ironclad is manned by Dwarfs from the same clan. Down the long years they repair and improve the ships, adding their own special modifications, tinkering with the controls and adding their own chapter to the Book of Armaments concerning their craft, its weapons and history. Each crew member is filled with pride in his ship and is convinced that it is the greatest fighting vessel afloat.[1a]
