Iron dragons are the most powerful of all ferrous dragons.
Iron dragons frequently assume the form of men to spy on the goings-on of the world, in order to someday bring dragons back as the rightful rulers of the land. Iron dragons are born with scales of flat black. As the dragon ages, the scales begin to take on a glossy texture until, as adults, the dragon is metallic black. The scales continue to take on silver highlights until, as great wyrms, the scales look like moonlight reflecting on a rippling pool. Iron dragons dwell upon great hills or on high mountains, usually building their lairs deep beneath the surface.
