Military action
The first war had only bred more hatred and even more understanding of the art of war.
The southern dwarves had now been chased away to their namesake, the South, in the first war. They lived on what now is called Fangador and Eastern Fereloqa. Considering their numbers, this wasn't a small amount of space, but they were a low self-confidenced peoples humiliated, which only ever brings conflict. The northern dwarves had magic and wisdom, but the southern dwarves discovered a few talents of their own, the mining of ore, the forging of metals and the crafting of real weaponry. The southerners pushed their way East over Fereloqa, surprising the high dwarves, but the conquest stood still at the Everon Mountains. A peace was made with the southerners somewhat prouder of their capabilities. After the war, the southern dwarves made sure to continue making inventions to get ahead.
