I would expect Vale to be the main kingdom when it comes to economy given its location. It has quick trade routes to all kingdoms and even used to have a tunnel to travel to the east of the kingdom where they can take the sea to reach Mistral. Atlas might be the main producer since it's full of robots and is also the HQ of the SDC but it's secluded so it has to depend on Vale to trade all of its resources to the other kingdoms. In fact, if Cinder's plan is to destroy Vale or at least hurt it badly, it would make sense since it would leave a big impact on the other kingdoms.

Then again, Mistral is basically the same since it's technically in the middle of Vale and Vacuo plus it's located around a huge amount of water. Instead of roads, they probably rely more on sea to arrive to their destinations.

As for Vacuo, you can notice what seem to be mountains in the colored map so you're probably right about the cliffs, Kunrin.
