Dragonborn

Dragonborn share some features with dragons, such as their scales, scale colours, and fire breath abilities, so it is likely they shared a common ancestor. However, the differences (eg. birthing live young, lack of even vestigial wings, physical size) suggest the divergence occurred a significantly long time ago.

Though they existed before The Flood they are not considered one of the Ancient Peoples, likely due to their relative scarcity and unclear origins.

Dragonborn tend to be physically larger than other humanoid peoples - averaging over 6' in height - but otherwise share a similar level of physical variance.

It is slightly more common - about 60% - for dragonborn to have tails than not.
