Just as Duten was convincing the panda people, the footsteps of distant Northrend, Alsace, officially set foot on the land of Icecrown Glacier.

Since the Burning Legion's defeat at Mount Hyjal, Arthas has recaptured Lordaeron from the Burning Legion's remnants of the Dreadlord.

Back in Lordaeron, Arthas was busy purging the remnants of the Burning Legion, but Illidan Furywind, who had been banished by the Night Elves, was invited by Kilgardan, who lured him into joining the Burning Legion, promising him great power to destroy the Lich King.

However, Illidan did not dare to go to Northrend, and he decided to search for the tomb of Sargeras and use the power of the Eye of Sargeras to destroy the Lich King and the continent of Northrend. After Illidan successfully found the Eye of Sargeras, he began to cast a spell in the ruins of Dalaran that tore through the continent of Northrend. Although Malfurion and the others came to stop it, they were also stopped by Duten's clone, and Illidan finally succeeded in casting this magic, and a strong earthquake occurred on the continent of Northrend, and the crystal used to contain the Lich King's soul also appeared cracks, and the Lich King's power quickly drained from the cracks.

However, this angered Illidan's brother Malfurion, who was the Grand Druid, believing that even the Scourge could not be destroyed at the expense of the entire continent of Northrend, so he suspended Illidan's spells, destroyed the Eye of Sargeras, and exiled Illidan again. Of course, if you look at it from another angle, it is not Duten who took Illidan out of the encirclement.

Illidan fled to the shattered world of Draenor in order to escape Kil'Gardan's punishment, but Kil'Gardan found him and ordered him to attack Northrend immediately to destroy the Lich King.

At this stage in the original book, Sylvanas Windranger, the dark ranger once controlled by Arthas, gained his own will, and then teamed up with several Dreadlords to stage a coup d'état, betraying Arthas.

However, this time, Sylvanas survived, so this time, although there were also undead who escaped from the Scourge Legion, but only a very few, and most of the undead were still controlled by Arthas.

At this time, Arthas had not yet properly handled the affairs of the kingdom of Lordaeron, and due to the loss of the Lich King's power, some of the Scourge soldiers broke away from the Lich King's rule and seized the coastline of the kingdom of Lordaeron. However, at this time, Arthas had no intention of fighting, and he did not have the energy to deal with these defecting undead. Because the Lich King found out that Illidan was heading for Northrend, if Illidan rushed to the Frozen Throne before Arthas, Neozu's entire plan would be in vain.

Arthas immediately rushed to the aid of Northrend, but on the way was intercepted by the elves of Quel'Thalas, these survivors of the undead scourge have now called themselves blood elves, and some have joined Illidan's army, although they have lost the leadership of Kael'thas Sunstrider, but these people are undoubtedly his diehards, when Kael'thas is sealed, these people have nowhere to go but to follow Illidan.

At the moment they are marching towards the Frozen Throne, and there is no doubt that these people are ahead of Arthas.

Attack? No, once these elves are attacked, Illidan in front of him will most likely know the fact that he has returned, and he will definitely speed up his pace, which will be even more dangerous when the time comes. So the detour? But if you take a detour, it will inevitably affect the speed of the return, and the danger factor is too high.

Just as Arthas was torn between a few words, the Cryptlord Anubaraq came to his side and led him through a series of ancient underground tunnels to return to the Lich King with the fastest shortcut.

When Arthas emerged from his burrow, he was faced with the last obstacle to his journey, Illidan, who had become a demon. Here, the Demon Hunter and the Death Knight engage in a one-on-one battle, and after an earth-shattering duel between Frostmourn and Aeginos, Arthas emerges victorious, and the defeated Illidan and his cronies flee back to the Outlands.

Some say that Arthas is a little man who willingly throws himself into the darkness, and he still knows what he is doing as he steps to the Frozen Throne; It is also said that he has been a puppet of the Lich King from the moment he picked up Frostmourn. Whatever the truth, when the Death Knight came to the rune armor in the ice, the Lich King's longing call for freedom took over his consciousness. Arthas shattered the Frozen Throne with the Frost Sorrow, donning the helmet of Neozu and becoming one with the Lich King. Since then, Arthas has become one of the most powerful monsters in the world of Azeroth.

In the final ending animation of Warcraft 3, Arthas is alone, hunched over his waist, struggling to move along the mountain road of the Frozen Throne.

In him, he could not find the slightest joy of victory, nor could he see the pride of the heroes, nor even the arrogance of the immortal king, but only a man who was dying of fate and curse, and was exhausted and dragged towards the end of his fate. Those painful and helpless memories that were repeated over and over again in his mind were the tragedy of his life.

Arthas ignored the voice that had been haunting him all the time, his past, and warned him not to make mistakes again, but that didn't stop him from crowning himself the Ice Crown.

Eventually, a new Lich King was born—and as Arthas sat on his throne with Frost Grief in his hand, it seemed as if the whole world was cut off from him, and the wind and snow covered his body. The kind of inseparable, lonely and lonely Xiao Suo, with the bleak and desolate elegy, echoes on the iceberg, just like the frozen throne standing between the ice sea.

It was only at the moment when he was about to fall into a deep sleep that several figures flashed in front of Arthas's eyes.

His lover, Gianna Proudmoore, the lovely girl, if he could, he wanted to marry her and have children, but unfortunately, he no longer had that right now; His father, Terenus Minethir II, a wise and powerful king, should have watched him grow old a little, and then, when he had no energy to govern the country, he took over the power from his father, but unfortunately, he killed his own father with his own hands, and did something inferior to that of a beast; Then, there is also his enemy, Lim Greymane, who is also a prince, and the other party's strength, power, and talent are not as good as his own, but now he has become such a person, and the other party must still be leading the Gilneth Kingdom to grow.

Forgive me, my love, that I have embarked on a path from which there is no turning back;

Forgive me, my father, for the mistake I made that no beast would make;

Wait for me, my enemy, and one day I will make a comeback, Lordaeron, only mine!

With such thoughts, Arthas fell into a deep sleep.

If nothing changes, Arthas will be fully integrated with the Lich King in five years' time. And what will happen to him in the future, only time will tell.

……

While Arthas fell into a deep sleep, Illidan also entered the Outlands through the portal, in this shattered world.

Consumed by the flames of vengeance, Mavi pursued Illidan incessantly. She and a small group of followers tracked Illidan through the portal. Illidan was outnumbered and eventually captured again. Luckily, Lady Vasqi and her Naga have recruited a new ally: the Blood Elves of Kael'thas Sunstrider. The Blood Elves soon followed the Naga to the Outlands and saved Illidan, only to capture Mavi.

Illidan promised to teach them how to satisfy their dependence on magic.

The Blood Elves swore allegiance to Illidan and helped their new masters close all portals to the Outlands. Through these efforts, Illidan hopes to be able to cut off the demon's reinforcements from the Warped Void and prevent Kil'Gardan from finding him.

Illidan's next target was the ruler of the Outlands at that time, the Abyss Lord named Mathridon. After gaining the affiliation of the local Shatterer Greytongue Clan, Illidan led a powerful army of Blood Elves and Naga to defeat Matheriton and capture his fortress, the Dark Temple.

But Illidan's victory did not last long. Accompanied by a storm of rage and magic, Kil'Gardan descended on the Outlands, and even if all the portals were closed, it could not stop him. Illidan grossly underestimated the power of the Demon Lord. After a quick thought, Illidan told Kilgardan that he had only come to the Outlands to put his army in order to eventually carry out an assault on the Frozen Throne.

Kilgardan barely calmed his anger, and he decided to give Illidan one last chance.

With no choice, Illidan led the Blood Elves and the Naga back to Azeroth.

The Scourge held Illidan's army off the coast of Northrend until the arrival of Arthas and Cryptlord Anubrekan. Arthas and Illidan had a one-on-one showdown, which ended in Alsace winning. Frost's Sorrowful Edge tore through Illidan's flesh, and he barely survived with his demonic viforce, leaving a wound that would not heal completely. It wasn't until years later that the cold wound was aching.

Illidan was defeated and retreated back to the Dark Temple. He asked his allies to keep the outer portal sealed as much as possible, while nervously preparing for the wrath of Ariten Kilgardan.

But the expected Legion invasion did not come.

While Illidan was reorganizing his army in the Outlands, he also began to secretly implement his own plans. He trained a group of demon hunters and formed Illidare, waiting for an opportunity to attack the Legion's world everywhere. Among them, Illidan personally led an attack on Nazriza, the Dreadlord's home planet in the Void, and stole the Seal of Argus from the Archives, a device that gave Illidan direct access to Argus, the former home of the Draenei and the base of the Legion.

Upon learning of Nazriza's attack, the Burning Legion immediately sent a large number of reinforcements to the area, and Illidan was waiting for this moment - he forcibly tore his own portal. And so the heavens and the earth changed, just as Neozu had turned Draenor into a shattered Outland, and the surging energy tore at Nazreza, and the entire planet was blown to pieces.

Since this planet is in the Void Realm, the souls of countless demons have been wiped out like their bodies, and they can never be resurrected. The Legion was furious at this, and in retaliation, they opened more portals in Azeroth and the Outlands.

The demons that poured out of these portals caught the attention of the upper echelons of the Alliance and the Horde.

In order to resist the threat posed by demons, the Alliance and the Horde sent a large army to attack the Dark Gate and make their way to the Outlands. The Demon Lord Kurul intends to set a trap on the Hellfire Peninsula to encircle and annihilate the Azeroth army. But Illidan discovered his plan and managed to thwart the siege.

Using the Seal of Argus, Illidan projected his soul into Argus' palace in Kilgardan, but before he could do anything, he was discovered by Kilkaldan. Just as he was about to be caught, a mysterious voice sent Illidan's soul back into his body. Illidan met the eldest, Naruzera, and learned all the secrets of Sargeras, the Burning Legion, and the true darkness that lurked in the Void.

In the original book, during the implementation of Illidan's plan, his army was constantly facing internal and external troubles. Driven by a demonic addiction, Kael'thas Sunstrider decided that Illidan could not satisfy the Blood Elves' thirst for magic and took refuge in the Demon Lord Kil'Gardan. He captured Naaru's ship and transformed it into a storm fortress, setting up massive mana furnaces to extract energy from the Void. Subsequently, Kael'thas began to refuse Illidan's command.

Vasqi was ordered by Illidan to extract energy from the lake in the Zangar Marsh, an act that led to the deterioration of the surrounding ecology. Eventually, Vaskey was killed by the druids of the Cenarion Expedition at the Viper Temple. Illidan's ally, Gruul, and his heirs were also defeated by the forces of the Alliance and the Horde.

When the plan didn't go well, but the army was defeated, Illidan began to become irritable and depressed. This makes Akama suspect that Illidan's essence is not very different from the previous demons, and begins plotting to assassinate Illidan. Illidan was furious at this, and took his soul to make the "Shadow of Akama" in his place, and Akama was sent to guard Mavi's prison. However, Akama gained the support of the Alliance and the Horde, and he secretly released Mavi and helped the Alliance and Horde armies in the siege of the Dark Temple.

At this time, Illidan's plan was at a critical juncture. He sent Kane Sunfury to lead his most elite Illidaray forces to a shattered world called Marton to seize the Sagritan Keystone, a powerful magic weapon that could access all worlds conquered by the Burning Legion. Illidare successfully completed their mission, but when they returned to the Dark Temple, it was Mavi and her watchers who awaited them. All of Illidare have been thrown into the new prison of the Broken Isles, the Cave of the Warden, where eternal imprisonment awaits them.

This time, however, without Kael'thas Sunstrider, the blood elves who were addicted to demons were mostly transformed into Illidare, and they began to satisfy their desires through evil powers. Without the greatest calamity, only the will of the universe knows how far Illidan can go.
