The dwarves of the Mountains of the Cast Iron City have lived peacefully for centuries. However, their society has grown too much in the mountain cities. Although the great king. Mordimus Anwemar, who ruled the dwarves with justice and wisdom, and the three groups rose in the dwarven society.

The Qinghu tribe, ruled by Lord Madolan Qinghu, was close to the king and was a champion of the traditions of the Cast Iron City Mountains. Ruled by Lord Cardeiro Wildhammer, the Wild Hammer tribe lives at the foot of the mountain range and on the cliffs in search of gaining more control of the city. The third party, the Black Iron Tribe, is ruled by the mage lord Saurisan.

The Black Iron Tribe hides in the dark depths of the mountain range, plotting against the Qinghu and Wild Hammer tribes. For a long time, the three tribes maintained a delicate peaceful relationship, but conflict erupted after the death of King Anwemar the Elder. Three tribes fought for control of the Cast Iron City. The underground of the dwarven civil war lasted for many years.

Eventually, the Qinghu tribe, with the largest army, drove the Black Iron Tribe and the Wild Hammer Tribe out of the mountains. Cadero and his Wild Hammer tribe migrated north, passing through Dun Algaz's barrier gate, in distant Grimm. Established its own kingdom within the Grim Batol Mountains. There, the Wild Hammer thrived and rebuilt its wealth. Saurissan's Black Iron was not lucky. Humiliated and enraged by their defeat, they swore revenge on the Cast Iron City. Leading the people to the far south, Saurisan founded a city (later named after himself) in the beautiful Red Bridge Mountains.

Prosperity and time were not in the slightest diminished by the hatred of the Black Iron tribes towards their fellow citizens. Saurisan and his mage's wife, Modgud, began to attack the Cast Iron City and Glynn Bartow. The Black Iron Tribe claims to claim all of Kazmodan for themselves. The Black Iron Tribes destroyed the strongholds of their compatriots and almost captured two kingdoms.

However, Madolan Qinghu eventually led his tribe to a decisive victory over the army of Saurissan. Saurisan and his retinue fled back to their own city, unaware of the battle at Glenn Barto, where Modegu was unlucky against Cardeiro and his Hammer warriors.

As she confronts enemy troops, Modgu uses her powers to bring fear to their hearts. She controls the shadows, and the dark creatures crawl out of the ground and attack them in their own palace. Eventually, Modegu breached the gate and laid siege to the fortress itself. The Wildhammer tribe desperately resisted, and Cardeiro himself gathered the wrath of the crowd and fought to kill the Magic Queen. With the fall of the Queen, the Black Iron Tribe collapsed under the wrath of the Wild Hammer, and the rest of the Black Iron Tribe forces were completely destroyed.

The allied forces of Cast Iron City and Green Bartow turned south, determined to deal with Sorisan and his Black Iron Tribe once and for all. They didn't go far, for Saurissan's anger led to a great upheaval. Seeking to summon a supernatural servant to ensure his victory, Saurisan awakens an ancient power that sleeps underground. Shocking him, and ultimately leading to his destruction, the summoning was far more terrifying than he had ever imagined.

Ragnaros, the Fire Lord of all Fire Elementals, was banished by the Titans at the beginning of the world. Now, unleashed by Saurissan's summons, Ragnaros has once again erupted against the creatures, and Ragnaros' return to Azeroth has destroyed the Redbridge Mountains and created a volcanic eruption at the center of destruction. This volcano, known as Black Rock Peak, borders the Scorching Valley to the north and the Burning Plains to the south.

Although Saurisan was killed by the forces he unleashed himself, his surviving compatriots were eventually enslaved by Ragnaros and his elementals. They are still on the mountain peaks to this day. Seeing this terrible cataclysm, with the fire spreading to the southern hills, Madolan and Cardeiro halted their army and hurried back to their country, unwilling to face the terrible wrath of Ragnaros.

Qinghu returned to the Iron City and rebuilt their glorious city. Wild Hammer also returned to Green Bartow. However, the Death Calamity Mountain Fortress of Modegu left a curse, and Wildhammer found it uninhabitable. They are saddened by the loss of their homes. King Qinghu offered Wild Hammer a place to stay outside the Cast Iron City, but Wild Hammer insisted on refusing.

Cardeiro led his people on the north of Lordaeron. Settling in the lush forests of the Hinterlands, Wildhammer founded the Eagle's Nest, where they were in close contact with nature and even united with the giant griffons there. Seeking a connection with their fellow citizens, the dwarves of the Cast Iron City built two massive arch bridges, the Thandol Bridge, which connected Kazmodan to Lordaeron.

Thanks to mutual trade, both kingdoms prospered. After the deaths of Madolan and Cadero, their descendants erected two huge statues in honor of their ancestors. Two statues guard the entrance to the south, which had become a volcano when Ragnaros awoke. They serve as a warning to those who want to attack the dwarven kingdom, and also remind the Black Iron Tribe of the price to pay for their crimes.
