At first, the other races were not even aware of the Dwarves. Not until the Wars of Fire (28-41 ASD), when the dwarven units joined the others to resist the Demons, were they recognized. Once the fighting was over, they returned to their homes under the mountains and had little to do with the other races for centuries. Slowly, tunnels were dug between the various dwarven cities, connecting then into a honeycomb deep beneath the earth.
