"Destroy the Scourge?"
Sylvanas's eyes lit up upon hearing this. The Forsaken broken away from the Scourge, were most worried about Arthas's retaliation. If the Scourge were destroyed, they would have no worries about the future.
Sylvanas didn't know the true strength of the Scourge, but recalling how Archimonde's Burning Legion hadn't gained any advantage in Dalaran, instead suffering heavy losses and retreating in disarray to Kalimdor.
Thinking about this, Sylvanas immediately lost confidence.
"Is Lord Kil'jaeden leading the team this time?" Sylvanas asked, her expression cold and hopeless.
Varimathras, ever cunning, quickly discerned Sylvanas's concerns and chuckled, "This time, Lord Illidan is leading the expedition. Your Majesty, please do not worry. A few days ago, Lord Illidan cast a spell in Dalaran, destroying the Frozen Throne. The Scourge suffered heavy losses, crippling its foundation. This is the perfect opportunity to eliminate them."
After hesitating for a long time, Sylvanas did not agree, but said tactfully, "I need to pray to Elune, the Moon Goddess, for her guidance. Please give me some time."
Inside the secret chamber, Sylvanas clutched the necklace, stroking its gems, and prayed devoutly to the Elune. Soon, clear images appeared before her eyes.
She saw a land covered in ice and snow, with a biting wind blowing, a towering peak collapsed, and countless Undead were reduced to dust.
She saw the Frost Dragon, half its body missing, crawling helplessly on the ice.
She saw the towering Abomination buried beneath the snow and ice, frozen into an ice sculpture, and the Death Knight's broken blade embedded in his stomach, lifeless.
She saw Arthas sitting on a Frost, his face covered in blood, Frostmourne in his hand already broken.
Surrounding Arthas, only a few Ghouls survived. With great effort, they dug out an Undead Mage from under the snow—none other than the Lich Kel'Thuzad.
At this moment, Kel'Thuzad was extremely weak and urged Arthas not to give up.
Arthas, leaning on the tattered Frostmourne, gazed at the sky and roared in despair. The broken Frostmourne gradually lost its light, and the power within him slowly faded.
The chaotic illusion shattered, Sylvanas abruptly opened her eyes, a smile playing on her lips.
It turns out the Scourge has weakened to this extent. Some now understand why Arthas hosted Duke Bolvar and promised to provide protection for Kingdom of Stormwind; these were all deceptive actions.
"Arthas, you almost fooled me. Your end is near." Sylvanas clenched her fists.
Poor Sylvanas had no idea that even gods could be unreliable.
Because of the Titans's shield, Elune's power is limited in Azeroth, preventing her from seeing through the mist-shrouded Frozen Throne.
As the only True God, the Moon Goddess has her pride. She cannot tell Sylvanas that even gods have limitations, so she can only fabricate an illusion, merely the Moon Goddess's speculation about the state of the Frozen Throne.
Elune, is concerned about damage to the Nexus and therefore must support Illidan's northward campaign. The cooperation between the Burning Legion and Sylvanas is crucial.
Having received guidance from Elune, Sylvanas had no further doubts and agreed to cooperate with the Burning Legion.
With the Legion's help, Undercity constructed a massive Legion Portal.
Upon hearing the news, the monster was overjoyed and led the mighty Burning Legion, the Fel Orcs Legion, Kael'thas's Blood Elves, and Vashj's Naga forces across the Dark Portal, then through the Legion Portal in front of the Dark Portal, directly to Undercity.
Sylvanas estimated that the combined forces were slightly weaker than Archimonde's 100,000-strong army, but the Scourge was currently much weaker, so victory was in her favor.
The monster, now determined and full of confidence, promised Sylvanas:
"I am not like Archimonde. Archimonde is extremely selfish, only concerned with improving his own strength, while I am willing to share the spoils of war with everyone. After the Scourge is defeated, I will repair Frostmourne and give it to you, Sylvanas. You will become the Lich King of Azeroth, leading the remaining Scourge Army. All I need is your loyalty."
Sylvanas was overjoyed upon hearing this and immediately knelt on the ground. "Lord Illidan, I will always be your most loyal servant."
The expedition to Northrend required a large number of ships, Forsaken's shipbuilding technology was inadequate. Fortunately, the Order of the Silver Hand, active in the Plaguelands, were of great help.
They felled trees, built ships in the ports of Tirisfal Glades, and combined them with the Legion's advanced technology to quickly create a powerful fleet.
Twenty-one years Dark Portal, Illidan led the Allied Forces on an expedition to Northrend and Sylvanas Dreadlords remained in Undercity, Big Candle Gagg, served as the sole recorder of the expedition, documenting this momentous campaign.
The Allied forces landed on the Borean Tundra. Lacking food and clothing, they slaughtered the Tuskarr lived on the coast, skinned them, and cut off their flesh to make frozen jerky. In the spirit of not wasting anything, the Undead Mage accompanying the army resurrected the corpses as Undead to serve as scouts for the Allied forces.
The allied forces did not head directly to the Frozen Throne, but instead approached the Nexus, the sacred site of the Blue Dragonflight. No one knows what price Malygos Aspect of the Blue, paid to send these bandits away.
Having tasted success, the monsters were not about to give up. The allied forces took a sharp turn and entered the Dragonblight, advancing on the sacred land of the Dragonkin, the Wyrmrest Temple.
The negotiations between the Red Dragon Queen Alexstrasza and Illidan remain a mystery to this day, and Big Candle Gagg doesn't know how to record them. After the allied forces left the Wyrmrest Temple, the Big Candle Gagg discovered that the Wyrmrest Temple's radiance had dimmed considerably, and the Dragonkin patrolling around it were extremely weak.
The allied forces plundered Howling Fjord, Grizzly Hills, Crystalsong Forest, Wintergrasp, and other places before finally entering Icecrown Glacier, the Scourge's stronghold, after they were satisfied with their loot.
What the monster didn't expect was that this was the beginning of the allied forces' misfortune.
Upon entering the Icecrown Glacier, the weather changed abruptly. A cold wind swept through the snow and ice, and howling sounds echoed in their ears. The sky was a hazy gray, making it difficult to see clearly. The allied forces trudged through the thick snow and ice, where visibility was terrifyingly low. Even the Demons's eyesight was less than ten meters.
The temperature here is extremely low, Vashj's Naga forces were the first to succumb to it. The Naga, who live in the sea, could not withstand such low temperatures and had to withdraw from Icecrown Glacier.
Then, terrible things happened. Every night, the allied soldiers could not sleep in the biting cold wind, and they would wake up exhausted. Soldiers of the allied army would mysteriously disappear, especially the Blood Elves, who suffered the most heavy losses. Even if they strengthened their defenses, it would be to no avail.
After traveling for several dozen days, Kael'thas felt that a mountain hollow ahead looked very familiar. When he got there, he realized that it was the very place where he had camped on his first night in Icecrown Glacier.
"Illidan, we're lost." Kael'thas looked grim. "I've asked the locals, and Icecrown Glacier has never had such terrible weather."
The monster believed this was related to the destruction of the Frozen Throne, which Steadfast its resolve to move forward.
