As Pit Lord had fought alongside the Burning Legion for many years, Magtheridon would never have relinquished his position as King of Outland without an order from Kil'jaeden.
If the monsters are to defeat the Burning Legion in Outland, their current strength is far from sufficient. The only way, as Kael'thas suggested, is to proceed steadily and develop gradually, which may offer a chance.
In terms of troop strength, although the Fel Orcs, infused with Fel, have become much stronger, they have sacrificed their sanity and are still no match for the seasoned Legion soldiers.
Then there are weapons, armor, and heavy weapons such as mechs and cannons, which the Fel Orcs Legion is far from adequately equipped with. If Magtheridon really goes all out and brings in a Star Destroyer that is already roaming outer space, the Fel Orcs Legion led by the monster will have no hope of winning.
In the Black Temple, Magtheridon roared in frustration. Even Mannoroth, the leader of the Pit Lords, was no match for Illidan, and Magtheridon knew his own strength was far from sufficient.
The Fel Orcs Legion marched towards the Black Temple, leaving behind countless deaths and ruins. The various races of Outland that survived the cataclysmic destruction were unfortunately ravaged by the Fel Orcs.
Along the way, Akama, who had gained Fel power and whose strength and confidence had greatly increased, did not care about Illidan's evil deeds, but instead gave him a lot of advice.
"Lord Illidan, the Black Temple is heavily fortified and teeming with Demons. A direct assault would be futile. I suggest a decapitation strike. We should attack through the Black Temple's sewers. I know a Secret Passage that leads directly into the command center. Kill Magtheridon, and the Burning Legion without a leader will inevitably descend into chaos."
The monster waved its hand with a smile and said Pride:
"What, have the servants of the Holy Light Draenei, also learned treachery? The Black Temple is insignificant; a direct assault is enough. Watch me annihilate it in an instant."
"That's probably not a good idea."
Akama was suspicious of Illidan's arrogance and hubris, as he was unaware of the unspoken understanding between the monsters and the Legion.
Attacking through the main gate was a deliberate arrangement by the monster. Even if Kil'jaeden was plotting something, the monster was strong enough to protect itself. Going down the sewers was actually the most dangerous option.
The Fel Orcs Legion stormed into the Black Temple through the main gate, but the Burning Legion was already on high alert. Pit Lord Magtheridon led a large group of generals out to meet the enemy.
Behind Magtheridon stood the bizarre and enormous generals of the Burning Legion, who looked imposing, but it was incredibly foolish of them to come out and fight directly.
Akama was shocked. How could this happen? Had the Demons, known for his cunning and treachery, lost his mind? Even Velen, who spoke so vehemently about protecting his people, had never been at the forefront of Charge, Prophet Velen had never defeated a significant enemy.
"Let me see who it is?" Magtheridon swung his massive body, pointing his Abyss blade at the monster. "Insignificant Night Elves leading a bunch of Orcs scum, daring to challenge the Legion's authority? All is over! Let us mourn your deaths."
"Magtheridon, you are not ready. I am the true Warlords of Draenor."
The monster soared into the sky and crashed down on Magtheridon like a meteor. The two engaged in a fierce battle in front of the Black Temple. Since they had a tacit understanding, the monster did not use its full strength and fought for a long time before finally subduing Magtheridon.
"I have seen countless worlds destroyed, roaring flames, burning skies, but I will never yield to you, Illidan Stormrage!" Magtheridon roared in defiance.
The monster frowned deeply, a slight shift in its memory. "The destruction I have witnessed far surpasses yours." Chains of Order of Arcane bound Magtheridon tightly.
After Magtheridon's defeat, the Burning Legion's generals all submitted to Illidan, and the Black Temple was captured without bloodshed, which made Akama even more suspicious.
It's important to know that the Burning Legion's soldiers are extremely loyal; even if their commanders are killed in battle, they will continue to fight, and it's rare to see Legion soldiers surrender voluntarily.
Illidan easily conquered the Black Temple and became the King of Outland. When the news spread, the entire Azeroth was in an uproar.
In the Battle of Mount Hyjal, the combined forces of the three races paid a heavy price but still could not stop the Burning Legion's advance. Meanwhile, Illidan ventured deep into Outland alone and, relying solely on the Fel Orcs Legion, successfully captured the Black Temple.
Illidan enjoyed immense popularity for a time, even surpassing the great Savior Thrall.
Like the shadow of a tree, many adventurers who had lost all hope in Azeroth crossed the Dark Portal and entered the Black Temple to pledge allegiance to "Illidan".
Monsters welcome all comers, but there are distinctions of closeness and distance. Night Elves and Blood Elves, in particular, have received the monsters' care, who personally infused them with Fel energy and formed the monsters' direct guard. This is how the Illidari came to be.
The monsters cooperated very well with Kil'jaeden. There were many factions within the Legion that opposed Kil'jaeden, such as the Dreadlords in Nathreza, the homeworld of the Void, Mardum in the Broken Abyss. In these operations, the monsters always remained cautious and never acted lightly without being sure of their success.
For Kil'jaeden and the monsters, Arthas and his Scourge had always been their coveted goal. Once the monsters had gathered enough strength and believed they could defeat the Scourge, a massive expedition began.
Maiev and her Watchers had just crossed the Dark Portal and were still adjusting to this world when they were ambushed by a premeditated attack. Kael'thas and Vashj's combined spells easily subdued Maiev.
"It's you, Kael'thas, Vashj! Why are you helping Illidan?" Maiev's eyes widened. Her former allies had betrayed her so quickly.
"I'm sorry, Maiev." Kael'thas always treated beautiful women with politeness. "Azeroth is entirely in league with the Orcs. The Blood Elves have nowhere to go but to seek survival in Outland. This is our pact with Illidan."
Maiev sighed, "I witnessed the Battle of Mount Hyjal. The Orcs devoured countless Night Elves, but we were helpless. Kael'thas, release me! I don't want Illidan to become the next Thrall."
Vashj walked over, swinging her four arms, and stared intently at Maiev. She smiled and said, "Watchers, do you feel any changes within your body?"
Maiev glared at Vashj. The two had probably met ten thousand years ago, but neither remembered it. Maiev said seriously, "I feel my power rising steadily, endless magic power flowing into my withered body. Can anyone tell me what's going on?"
Vashj's expression turned grave. "Maiev, we've all been tricked. Elune, the Elune, Pain Suppression our power. Stay in Outland with us; that's the true freedom of the Night Elves."
At the port of Northrend, Duke Bolvar boarded the Stormwind Soar and embarked on his journey home.
Recalling his secret talks with Arthas, the Duke was not satisfied with the negotiations. Arthas seemed indifferent to the safety of Stormwind City, his mind completely absorbed in other things, which Bolvar guessed were the New World he had mentioned many times.
This reassured the Duke that Arthas had no ambitions toward Kingdom of Stormwind.
The Duke recalled Arthas's parting words, "To protect Kingdom of Stormwind, a price must be paid. In the near future, I need a reliable candidate to become the new Lich King, so that we can continue to protect Azeroth and humanity."
"A reliable candidate?"
Bolvar stared blankly at the sky, one face after another appearing in his mind, which he rejected one by one. At his level, he could no longer trust anyone but himself.
