The gnomes separate themselves into two groups that are exactly the same except for their curiosity. Some gnomes are born with a natural curiosity and need to know how things work. They live in an artificial mountain in the middle of the plains where they conduct their experiments. Most of the experiments fail or go awry. They have blown up the mountain twice in recorded history and finished rebuilding from the last time 50 years ago.
They other gnomes are much more down to earth and settled. They have a small city near the base of the mountain and can also be found in any large human settlement.
