The gigantic Thrall and Garrosh waged a great battle in the Barrens. With the support of the Blackhand behind the scenes, both of them had become terrifying beings capable of destroying the world.
This battle was far from over. Robbie opened Portal to Northrend, sending Vanessa back to Icecrown Citadel. He instructed Vanessa to find Kel'Thuzad, study the mysterious energy stolen from the flesh, and then devise a solution.
Robbie remained in the Barrens, keeping watch on Thrall and Garrosh.
The two fought fiercely in the Barrens for many days. The intense collision of Lava and ice caused a large amount of water vapor to rise into the air, forming thick cumulonimbus clouds. The rain grew heavier and heavier, forming a great flood that flowed down the Barrens to the Thousand Needles.
The Thousand Needles is a unique landform formed by glacial erosion. It is located in a low-lying area and is home to a large number of Tauren. The Tauren have been able to withstand repeated slaughter and consumption by Orcs, all thanks to the active reproduction of the Thousand Needles.
A raging flood poured down from the Barrens, turning the Thousand Needles into a vast ocean. The home of the Tauren was destroyed, and countless Tauren became floating corpses.
The Shimmering Flats, which borders the Thousand Needles Plains, was not spared either; the famous Shimmering Flats desert racetrack has become an underwater relic.
A small number of Tauren climbed to the high ground and escaped the disaster. Looking at the rising waters and the destruction of their homes, the Tauren cried out in despair.
"Earth Mother protect us, why is this happening?"
"I've heard that Thrall Savior, and Garrosh, the Warchief, have joined forces to fight a terrifying being in order to save Azeroth," a well-informed Tauren whispered.
"What kind of terrifying being is it?" a Tauren roared angrily.
"That terrifying being is intangible and invisible; it is extremely mysterious."
Tauren are not stupid; most of Tauren know who destroyed their homeland. However, their fear of the Orcs is ingrained in their bones, and they would never dare to speak ill of Thrall and Garrosh.
The surviving Tauren gazed at their destroyed homes and could only silently pray to Earth Mother, as rain washed over their faces, mingling with their tears.
After the Lava in the Barrens was completely depleted, Garrosh flew towards Ashenvale.
Thunder Peak, located in the middle of Ashenvale, was originally a lush mountain covered with dense primeval forests and home to a large number of Furbolg.
The Furbolg were unaware that Thunder Peak was a long-dormant volcano, its last eruption occurring thousands of years ago.
Garrosh sensed the surging Lava inside Thunder Peak crashing down like a meteor, igniting the mountain's primeval forest. Then came a violent earthquake, with massive amounts of Lava erupting from the mountain. Garrosh, bathed in the Lava, stared expressionlessly at Thrall was pursuing him.
Thrall borrowed a large amount of water from Astranaar Lake and the surrounding waters, and the Lava and ice collided again as the two continued their almost identical battle.
The Night Elves of Astranaar were stunned. Gazing at the world-destroying battle in the sky, they all showed expressions of terror. The news quickly spread to Darnassus. Upon hearing the news, Tyrande could only pray to the Elune and dared not leave Darnassus.
Although Tyrande was not leading them, the Night Elves recognized the crisis and took timely action. The Night Elves of Astranaar were the first to retreat, followed by Auberdine on Darkshore, where the Night Elves began to migrate north.
The Orcs at the Splintertree Post watched the great battle in the sky and cheered enthusiastically. Before long, a rain of fire fell from the sky, and a large number of Orcs were burned to ashes.
This was a world-ending battle, and many beings on Azeroth were silently observing it.
After the Lava in Thunder Peak was exhausted, Garrosh retreated towards Darkshore.
Both Garrosh and Thrall harbored deep hatred for the Night Elf race, which influenced their actions to some extent. They were eager to extend the war to the Night Elf capital, Darnassus, and eliminate this major threat to the Orcs.
Thus, Auberdine on the Darkshore suffered a calamity, with countless houses being completely destroyed, and Garrosh tearing the land apart in the same way he treated the Barrens.
Unexpectedly, a massive tornado suddenly appeared, Wind Rider, Al'Akir atop it, letting out a thunderous roar:
"Get out of here."
Garrosh and Thrall immediately turned around and wisely chose to retreat, abandoning their idea of invading Darnassus.
After all, Garrosh and Thrall were evenly matched, and if Al'Akir Wind Rider only helped one side, the other would inevitably lose. Neither of them wanted to offend this Elemental Lords.
Garrosh retreated south, and the two passed through the Desolace, triggering a massive earthquake that destroyed Feathermoon Stronghold in Feralas. They eventually returned to Tanaris, causing a massive tsunami that completely destroyed Steamwheedle Port and caused sea levels to rise.
Garrosh knew that to win, he would need a large amount of Fire Elementals support, while Thrall could utilize the almost inexhaustible Water Elemental Power in the sea.
To reverse this unfavorable situation, Garrosh must find a large gathering place for Fire Elementals. In Kalimdor, only the Firelands of Mount Hyjal possesses this condition, but he does not believe he can wrest control of the Firelands from Ragnaros.
Therefore, Garrosh turned his attention to the Eastern Kingdoms.
Garrosh crossed the Great Sea and landed in Stranglethorn Vale; his ultimate goal was Blackrock Mountain.
Located at the junction of Searing Gorge and Burning Steppes, Blackrock Mountain is the most active volcanic group in Azeroth. If Blackrock Mountain were to erupt, it would trigger a chain reaction, causing all the volcanoes to erupt simultaneously, resulting in earthquakes and tsunamis, and the entire Eastern Kingdoms would be destroyed.
Garrosh cared nothing for the suffering of the people; victory was all he cared about.
Thrall saw through Garrosh's thoughts. He, too, didn't care about the safety of the Eastern Kingdoms; he simply couldn't afford to fail. He calmly said:
"I won't let you have your way."
Thrall summoned endless seawater to ambush Garrosh in Stranglethorn Vale, and their battle severed Stranglethorn Vale in two.
Lacking the support of Lava power, Garrosh was at a disadvantage. He flew into the air, transforming into a fiery meteor, and fled towards Blackrock Mountain.
Do you think you can escape?
Thrall pursued Garrosh all the way to Loch Modan, the territory of the Humans. Thrall gathered the Water Elemental Power and almost drained the water of Loch Lake, forming a barrier to block Garrosh.
Garrosh had no choice but to gather his last strength, break through the Stonewrought Dam, and successfully pass Thrall's blockade. Under Thrall's pursuit, Garrosh chose to detour and flew all the way to the Badlands.
The Badlands, adjacent to Blackrock Mountain, also has a large number of volcanoes. Garrosh successfully ignited the volcanoes in the Badlands. Although the Horde's Horde in Kargath in the Badlands was accidentally destroyed and thousands of Orcs perished in the flames, Garrosh did not take it to heart.
At this moment, Garrosh was only a step away from Blackrock Mountain, and he also possessed enough Lava power.
Although Thrall felt he had miscalculated somewhat, he wasn't worried. The Badlands was near the sea, which meant it possessed an endless Water Elemental Power.
The two were evenly matched once again, and a major battle was about to break out.
