Ragefire Chasm in Orgrimmar's the Drag was originally a cave leading deep underground, down to Lava, and was home to a large number of Elemental.
In the early days of Orgrimmar, before the Orcs had a firm foothold, Thrall reached an agreement with the Elemental of Ragefire Chasm, agreeing not to invade each other's territory.
As the Orcs gradually gained a foothold, Thrall immediately turned against them. On the surface, the Orcs abided by the agreement, but in secret, they sent adventurers to invade Ragefire Chasm.
Thanks to the adventurers' continuous efforts, the Elemental in Ragefire Chasm dwindled in number. After Garrosh became Warchief, he simply tore up the agreement and wiped out Ragefire Chasm in one fell swoop.
Today, Ragefire Chasm has been transformed into an underground fortress, and Garrosh's new throne lies at its deepest point.
The Emissary brought Thrall to Garrosh's throne and gave the command:
"Thrall, Elune, has high hopes for you. I hope you will not disappoint Moon Goddess."
Thrall grinned, his face serious, and said, "My Emissary, please tell Elune, that I will surely triumph."
The Emissary glanced at Garrosh and solemnly announced, "Today, only one Orcs can ascend to the throne and become king."
On his throne, Garrosh watched the Emissary depart and began to understand something.
No one achieves success easily. A mysterious entity behind the scenes is willing to help Garrosh, but the test from Elune, is the price Garrosh must accept.
Thrall surveyed the Throne Room. Before Garrosh lay a red crystal, and hanging from the ceiling was a purple heart— the Heart of Darkness of Y'Shaarj.
"Garrosh!" Thrall's expression turned nostalgic. "Do you remember when I sent someone to bring you from Nagrand years ago? Back then, you were just a naive farmer who had never seen the world. I was the one who showed you this wonderful world. I never imagined that today we would be facing off against each other."
"Thrall!" Garrosh's face twisted in a grimace, forcing a hideous smile. "Who has brought us to this point? Was it your ambition, or my cruelty?"
"It is our Destiny," Thrall sighed softly.
Garrosh chuckled. The red crystal before him displayed the battle situation in Orgrimmar. Garrosh casually commented:
"Look at these wretches, the Kor'kron Dark Shaman, Earthbreaker Haromm, and Tidespeaker Kardris. To be honest, I admired them greatly, but they knew too much, so they had to die. Damn it, that wretched Gamon, supposedly hanging them from the tree to boost morale, but his real purpose was to show his loyalty to the invaders and lure the enemy to Nazgrim."
Thrall said casually, as if making small talk, "I heard you killed Nazgrim's whole family."
"He's just a piece of trash; I've never taken him seriously."
Thrall and Garrosh watched Nazgrim die in Anjing, as if they were watching a dog die before their eyes.
Garrosh stood up and looked down at him, saying:
"It's getting late, Thrall. Let's begin our duel to the death. Those who survive can leave before the Alliance and Horde arrive."
A vast amount of Elemental Power gathered around Thrall, and four enormous figures loomed behind him.
Those were representatives of the four elements: earth, fire, water, and wind, who were willing to lend Thrall power. Two of them were Elemental Lords, while the other two were traitors from their respective factions.
Thrall slowly raised his head, the Elemental Power changing his appearance, his features filled with majesty:
"I feel an unprecedented power, such vast Elemental Power, as if it can control everything. Garrosh, how confident are you in defeating me?"
"Our Orcs Destiny is sealed from birth; we must fight bravely for our limited living space, and the losers will only die." Garrosh prepared to merge with Y'Shaarj's Heart of Darkness.
Thrall calmly said, "Garrosh, you should know very well that we've come to this point. We're all just pawns, either fighting each other on the chessboard or reaching a private agreement so that everyone can survive."
Garrosh sneered, "So you're afraid of death."
Thrall retorted, "Aren't you afraid of dying?"
Garrosh's expression was solemn. How could someone of their status, who had enjoyed worldly riches and honors, wielded immense power, and whose word was law, possibly bear to die?
Those who are not afraid of death are generally strivers, or those on the road to success.
Those who truly reach the pinnacle of power often cherish their own lives exceptionally.
Garrosh hesitated for a long time, then understood Thrall's plot and sneered:
"I know what you're waiting for: for the Alliance and the Horde to come crashing down on me, then you can win without a fight."
Thrall cautioned, "The Elemental Power the Emissary lent me can only last until the Alliance and Horde attack. By then, you'll have fused with Y'Shaarj's Heart of Darkness, and who can kill you then?"
Garrosh came to the new Throne Room with that in mind; he didn't want to die in Orgrimmar.
"Thrall, you saw right through me. Good, this way none of us will die."
Rather than a life-or-death duel leaving only one survivor, it's better to cooperate tacitly so that both can survive. Thrall and Garrosh are both intelligent people and know how to make the right choice.
The two observed the Alliance and Horde's invasion. After killing Nazgrim and entering the underground fortress, the Alliance and Horde suffered repeated setbacks. The dark Power Infusion Malkorok, the traps guarding the Pandaria loot, the Thok the Bloodlust, and the siege engineer Blackfuse all caused considerable trouble for the Alliance and Horde.
Thrall asked with interest, "I've heard that the Klaxxi Paragons are the most loyal warriors among the Mantid. How did they come to pledge allegiance to you?"
Garrosh shrugged and replied, "The Grand Empress Shek'zeer doesn't like them; the Klaxxi Paragons are just protecting themselves."
Thrall scoffed, "What a pity, these insects have met the wrong person."
Garrosh disagreed.
After the Klaxxi Paragons were defeated, the elite forces of the Alliance and the Horde stormed into the Throne Room. The powerful Elemental Power surrounding Thrall quickly dissipated, yet Thrall wore a smug expression.
"Garrosh, your death is near. This heart is not the Y'Shaarj's Heart of Darkness, but merely the Heart of Ra-den. The Alliance and the Horde have found a way to deal with it. Today is your end."
Garrosh showed a slight look of surprise, but then relaxed and chuckled, saying:
"I see, but it won't affect anything. I've already discovered another use for this heart; I've been stalling for time, waiting to complete the spell."
Ra-den's heart exhaled a purple, dark aura that enveloped Garrosh's body, after which Garrosh vanished.
Thrall was startled and whispered:
"Could it be Void? Damn it, he managed to escape."
After the teleportation was complete, Garrosh opened his eyes and looked around.
This is a dilapidated temple, clearly looted. Everything that could be carried away is gone, and murky Flowing Water flows freely, with bloated corpses floating on the surface.
On a broken stone tablet at the temple entrance, Garrosh saw a line of text:
Temple of the Jade Serpent.
"So I was teleported to the Temple of the Jade Serpent of the Azure Dragon in Pandaria."
The location of Ra-den's Heart's teleportation is not fixed, and Garrosh hasn't fully figured it out yet.
Just then, the sound of footsteps approached.
