The Ogres have been keeping an eye on Oshu'gun for a long time. Ever since the Draenei first arrived in Draenor, Ogre Mages have lived nearby to gather firsthand information.
Long ago, the Gorian Empire had detected the existence of Naaru K'ure. Although K'ure was still seriously injured, he still possessed terrifying strength. In addition, the Army of the Light's attitude was ambiguous, so the Ogres dared not openly kill a Naaru.
Now that K'ure is on the verge of destruction, and the Army of the Light has made it clear that they are abandoning K'ure, only then did Imperator Mar'gok dare to send Ogre Mages to assist Cho'gall deep into Oshu'gun.
However, this terrifying ghost had not been detected in previous reconnaissance efforts.
After the three-headed Cyclops fell, Cho'gall realized he was no match for him. He glared fiercely at the mysterious ghost and shouted the order:
"Retreat! Retreat immediately!"
Cho'gall and his Ogres retraced their steps and ran out of Oshu'gun Mountain in one go.
Feeling the bright sunshine, Cho'gall felt frustrated, his eyes darting around, wondering where this ghost had come from.
An Ogre Mage asked in a low voice, "Sir, are we just going to give up like this?"
Cho'gall shook his head and said coldly, "I've heard that Holy Light has a restraining effect on ghosts."
The mage said with difficulty, "But we don't have any wizards among us who study Holy Light."
Cho'gall pondered for a moment, then his eyes lit up. "It's alright, the construction site of Oshu'gun is nearby. After receiving Velen's letter, the Lightforging Draenei are willing to become our slaves. As long as we get some Lightforging Draenei to help, this ghost is doomed."
The mage nodded in agreement. "I've heard that Lightforging Draenei explode upon death, releasing Power of the Holy Light they've accumulated in their lives. At worst, we can just make them all self-destruct."
Cho'gall roared defiantly, "Damn ghost! I refuse to believe that a hundred Draenei self-destructing won't kill him!"
Shortly after Cho'gall left, another group arrived, led by Durotan and followed by three Orcs chieftains.
Cho'gall's group's actions did not escape the notice of the Sentinels dispatched by Durotan. Upon receiving the news, Durotan immediately led his troops to the scene.
Beside Durotan, Grommash Hellscream surveyed the precipitous mountain peak, secretly astonished:
"This is the sacred ground of the Orcs. Our Warsong Clan warriors most wish to be buried here after their deaths. What are these Ogres doing Oshu'gun?"
Durotan frowned. Oshu'gun was a sacred mountain where the Ancestral Spirit Orcs ancestors could often be seen, Legendary that souls could live forever there.
"Let's go in and take a look!" Durotan waved his hand and said.
Several Orcs led the way, Cho'gall's Ogre Mages had cleared the obstacles, allowing the group to safely reach the depths of the mountain.
"Orcs, go back. This is not a place for you."
The mysterious ghost reappeared, sensing the Power of the Holy Light of the Lightforging Orcs. The ghost revealed a greedy look, and golden light gleamed in its eye sockets.
Durotan carefully examined the ghost before him, sensing that its body was like a bottomless quagmire capable of swallowing everything.
"May I ask your esteemed name?" Durotan asked politely.
"My name? I've long forgotten it. I've been here since I woke up, and I don't remember anything from before."
The ghost shook its head in confusion, its expression quickly turning serious:
"I must protect Oshu'gun and not allow anyone to approach K'ure. This is my duty. If you venture any further, don't blame me for being impolite."
"K'ure?" Durotan exclaimed, searching his memory.
"This is the name of Naaru. A Naaru is hidden in Oshu'gun."
Kilrogg said viciously, "A ghost dares to challenge the Holy Light? May it be reduced to ashes under the Holy Light!"
Those who followed Durotan were all elite Lightforging Orcs. Under Kilrogg's command, they fused their Power of the Holy Light together to form a terrifying sphere of Holy Light, radiating intense light like a small sun, which crashed down on the ghost.
The ghost, without looking to the side, slowly opened his arms as if to embrace the Holy Light Orb. Upon contact with him, the Holy Light Orb was directly absorbed by his body, leaving no trace.
"What kind of power is this?" Kilrogg felt a chill run down his spine. Although there was an Undead Paladin beside him, he never expected that a ghost could absorb Holy Light.
"Holy Light, I need more Holy Light."
Unable to control his greed, the ghost appeared almost instantly beside a Lightforging Orcs, reaching into the Orcs's body with his arm.
In the blink of an eye, the Lightforging Orcs collapsed to the ground in agony, all his Power of the Holy Light vanishing completely.
"Oh no! Brave soldiers, cover our retreat!"
Durotan hastily retreated, with Grommash Hellscream, Kilrogg, and Blackhand following behind, and Spectre chasing after them, absorbing any Lightforging Orcs it encountered.
The ghost only absorbed the Holy Light and did not kill anyone. It chased the ghost all the way to the pass of Oshu'gun before reluctantly returning to the mountain's interior.
It seemed that some force was binding the ghost, preventing him from leaving Oshu'gun Mountain.
Having successfully escaped from Oshu'gun, everyone breathed a sigh of relief, and the Orcs, whose Holy Light had been drained, also struggled to crawl out.
Grommash Hellscream suddenly seemed to remember something and whispered:
"I know the origin of this ghost."
Meeting Durotan's expectant gaze, Grommash Hellscream vividly described:
"I've read in the ancient Warsong Clan documents that two hundred years ago, High Archbishop Hattemas, Velen's Adjutant, led a group of Draenei into Nagrand. Near Oshu'gun, they were overtaken by Velen. Before his death, Hattemas swore an oath to rescue K'ure, even at the cost of his life."
Durotan pondered for a moment, then said, "Could it be that Hattemas has truly transformed into a ghost to guard K'ure? Grommash Hellscream, do you have a solution?"
Grommash Hellscream grinned menacingly, "Once we find Hattemas's remains and grind them to dust, he won't be able to cause trouble anymore. I happen to know where they are buried."
It sounded very unreliable, but Durotan had no choice. He nodded and ordered, "Lead the way."
Not long after Durotan left, Khadgar secretly infiltrated Oshu'gun alone.
"Cho'gall failed, and Durotan can't get in either. It seems there's danger lurking in Oshu'gun."
Cho'gall's Ogre army remained largely intact, and Durotan's Orcs suffered no losses whatsoever. This was the source of Khadgar's confidence in venturing deep into Oshu'gun.
It's dangerous here, but not fatal.
Once inside the mountain, the ghost reappeared and shouted:
"Human, this is not a place for you. Go back."
Khadgar stared at the ghost in surprise. "You know I'm human?"
There are no humans in Draenor World. The ghost recognizes Khadgar's identity, proving that he has seen humans before.
The ghost shook its head in confusion. "Strange, how do I know you're human? Have we met before?"
"Yes, we met. We were very good friends when we were alive."
Khadgar carefully observed the other person's expression, probing little by little.
Seeing that the ghost did not show any hostility and seemed to be deep in thought, Khadgar, with his silver tongue, said:
"Don't you remember? Together we crossed the Dark Portal, fought the Iron Horde, and built a fortress in the Lunarfall."
"Then who am I?" the ghost pressed.
"You are Tirion Fordring Argent Crusade and Highlord."
Khadgar said in a serious tone:
"You went missing during the war against the Iron Horde, and I've been looking for you ever since."
