Unlike other species, the Dragon Race mastered fire early on, directly bypassing the barter stage. They leaped straight into the era of precious metal currency economics, thus gaining a significant lead over other species.
The obsession Dragons had with gold and silver was largely because the initial temperature of dragon flame was very low, far from the melting point of iron (1,538 degrees Celsius), but the melting point of natural gold (1,063 degrees Celsius) and silver (961.93 degrees Celsius) was sufficient.
As wealth began to circulate, merchants and craftsmen started to appear sporadically among the clans. For a long time, the Dragon Race did not generate a unit such as the farmer. They practically advanced into the stage of nomads, stepping onto the path of a classical commercial kingdom.
