The Notes to Herald a New Age
Dragonborn are rare in your part of the world, but they’re not unheard of.
The Dragonborn are divided into clans. Most often than not they’re having some grudge against another clan, maybe even several. Their code of conduct are largely determined by the specific dragon they’re related to. The Metallic dragons (Gold, Silver, Brass, Bronze and Copper) are largely Lawful while the Chromatic (Black, Blue, Green, Red and White) are largely Chaotic.
They have a nation of clans in the western continent governed by tribal rules.
