A race of two worlds.
The Rock gnomes are the leaders in science and technology while the forest gnomes adapted to being the herbalists and alchemists of the city. Unlike the elves, the gnomes have no hate to each other despite their different views on science or technology. In the end they are both servants to their own curiosity.
It was the inclusion of the rock gnomes to Ashen Grey that truly made it what it is today. The king, seeing their potential, has given many rock gnomes free rein in their experimentation. This has led to miraculous breakthroughs, but also hundreds of small disasters. It isn't uncommon for the city guard to be busy hunting down or cleaning up some rock gnomes latest experiment.
When the wood elves finally decided to give way and join the city so did their allies the forest gnomes. Rather than sunning themselves to the countryside however these gnomes decided to root themselves in the city's community as herbalists and alchemists. This choice led to some feelings of betrayal from the wood elves, but the forest gnomes still stand as the wood elves closest ally given their necessity for plants and wildlife to create their potions. This at the very least has shone the elves that these gnomes haven't abandoned nature completely.
