Metallic Dragonborn

Descended from the celestial dragons of law and order, the metallic dragonborn come in the colors of gold, silver, brass, bronze, and copper. They are less materialistic than their chromatic cousins Instead they prefer gains in knowledge and experience.
Metallic dragon are incredibly good at blending in with humanoid society. Part of the reason they can pass off as good in the eyes of others is their ability to temporarily take on a form that can be mistaken for human or even aasimar. This shapeshifting ability is not exclusive across full dragons, but is rarely present in chromatic or gem breeds.
The heavily virtues that inspire the many peeks of Mt. Celestia were inspired by the many breeds of metallic dragons, and their connections to the archangels. As a result virtue is a common attribute that is striven for in metallic dragonborn culture.
