Metallic dragons were a type of dragon distinguished typically by the color and composition of their scales, that was like that of various metals, hence the name. They were generally good, altruistic, and righteous creatures. Despite their relatively benign nature, metallic dragons were also aggressive when threatened or challenged. They usually worshiped Bahamut, whom they regarded as their king. It was believed by scholars from Candlekeep that all species of metallic dragons evolved from the proto-dragon species of the ferrodraco genus.
