Gold Draconium is one of the 13 different colours of Draconium found on Draconis and in Dragon City, as well as being considered as one of the five main draconium colours. This colour of Draconium is considered the "original" colour for all Draconium; the modern day range of colours we see today all evolved from Gold, due to the environment and different needs shaping dragons and humans in different ways.
It is unknown what people who fall under the primary influence of this colour tend to be like, as the series has only ever had one such person (and spoken of another). The two people known to have Gold as their primary influence are the current Dragon Booster and the Ancient Dragon Booster- from this, it is suggested that people who fall under this influence tend to be lawfully good, as well as an archetypal hero.
Gold Draconium dragons, commonly referred to as Star-Class dragons, are an extremely rare colour of dragon. Unlike other dragons, they can use every colour of Draconium Gear. Like the colour of their Draconium influence, they are considered the ancestors to the modern day coloured dragons. Not much else is known about them as they were considered extinct, until Beaucephalis was bred by Connor Penn.
