Killing and madness are fascinating, even for a Titans.
With the major powers of Azeroth tacitly approving Illidan's actions in Azsuna and attributing it to an invasion by the Burning Legion, Aman'Thul quickly spread the flames of war to the entire Broken Isles.
The Broken Isles were quickly engulfed by raging Fel Flames, forcing the Murlocs, Naga, Sea Giants, and others who had lived there for generations to flee the dangerous land and struggle to survive on nearby islands.
Being able to enter the ocean is considered good, Demons dislike the sea.
The Vrykul of Stormheim, the Druids of Val'sharah, the Tauren of Highmountain, and the few Orcs who survived Gul'dan's attack on the Tomb of Sargeras —almost all of them suffered extermination. Their settlements were burned, and all their people were slaughtered.
Odyn's Hall of Valor rose rapidly into the air. The Val'kyr coldly gazed down at the countless wailing souls below, unwilling to accept even one more. Odyn, on his throne, lowered his proud head, his heart trembling.
Helya's ghost ship sailed into the vast ocean. Helya's enormous body stood on the deck, bewildered and helpless, gazing at the helpless Restless Souls of the Broken Isles, unable to help them enter the world of the dead.
The fresh blood and flesh strengthened Aman'Thul's Demons Legions, for which he made some concessions, wisely disguising Legion Demons as Eredar Mages, Doomguards, Demons Lords, and so on.
Indulgence led Aman'Thul further and further down the path of madness. Apart from being careful not to use the Arcane power of the Titans to avoid being discovered by the Elune, the increasingly insane Aman'Thul had no scruples left.
With the Broken Isles engulfed in war, Aman'Thul's Demons Legions were now able to crush the Vault of the Wardens.
Inside the Vault of the Wardens, the new the Jailer Cordana Felsong, is increasingly bewildered by the recent situation. The sudden appearance of these Demons Legions has left her completely unprepared, and she doesn't even know who the enemy is.
She quickly sent some Demons to gather information, and soon a clever Flame Imp brought back news.
"The Jailer, rumors are Legendary the Broken Isles have been attacked by the Burning Legion, but according to our observations, the leader of this Demons is Illidan Stormrage, it's absolutely true."
"Impossible, you're lying to me." Cordana Felsong vehemently denied it. She stepped forward and killed the Fel Imp who had risked his life to gather information, proudly declaring, "My Illidan is so gentle and kind, definitely not that Demons leader outside. Go and gather more information for me."
Cordana Felsong was stubborn and proud; she was definitely not a qualified leader. Seeing this, the low-ranking Demons had no choice but to hide the truth in order to survive, telling the new the Jailer that the Demons outside were the Burning Legion and that their leader was the Kil'jaeden the Deceiver.
Upon hearing that it was an invasion by the Burning Legion, Cordana Felsong was finally satisfied. She believed that the Alliance and the Horde would definitely not stand idly by, so she had nothing to worry about and only needed to wait for Illidan.
Not long after, she received news of "Illidan"; Aman'Thul sent her a letter:
"I am Illidan Stormrage. Hand over the Key to the Worlds, release my servants, and join my Legion, or I will tear your soul apart with my own hands and forge your exquisite and beautiful body into the most vile Demons."
Along with the letter came a small box. Inside was a translucent green bead, its surface emanating an aura of Fel, with beautiful rays of light flowing around its core.
Cordana Felsong's face was ashen; she knew perfectly well what this bead was.
The Fel Essence, also known as the Greater Demon Core, marked the end of her near-perfect flesh and blood body as Night Elf. Her body was torn to pieces, and Fel energy flowed through her veins, transforming her into Demons that lived by absorbing Fel.
She thought of the Illidari imprisoned in the Vault of the Wardens, those Demon Hunters she loathed so much. Now, she, the Jailer, had become one of them—how ironic!
"No, no, Illidan wouldn't do this to me." Cordana Felsong knelt on the ground, wailing in agony. Only then did she remember Maiev's warning and realize that she had truly been tricked.
After the endless sorrow subsided, Cordana could only helplessly accept reality. She picked up the Fel Essence, trembling as she put it into her mouth. With a muffled groan, her eyes emitted a burst of Fel.
The Key to the Worlds is escorted by a group of Scythe Demon as Felguard. These creatures are irrational, cruel by nature, and only see brutal killing. They identify each other by their scent.
Robbie, holding the Black Cat's black disc, also transformed into the form of Scythe Demon, possessing the same scent. He easily blended in, and the unintelligent Scythe Demon failed to notice the extra member in the group.
The Key to the Worlds must be placed on the strongest Scythe Demon. Robbie stepped forward, knocked him down, and obtained the right to escort the Key to the Worlds. He made contact with the demon using the golden disc, and then voluntarily returned it.
The strongest Scythe Demon shook its head; its intelligence was insufficient to comprehend the meaning of this series of actions. The group of Scythe Demons paid no attention to when Robbie appeared or left.
The madman Aman'Thul obtained the Key to the Worlds, completely unaware that it had been tampered with. With the addition of the Eye of Aman'Thul, his plan was more than half complete.
Although these actions were too reckless and teetered on the edge of danger, they could be detected by the Elune at any moment.
But it must be said that the results were excellent. What would have taken years to complete was nearly accomplished in just a few months. Now, all that was left for him to reach his final goal was the Tomb of Sargeras.
The Tomb of Sargeras was originally an ancient temple dedicated to the goddess of the moon. It is said that the guardian Aegwynn used this sacred temple to seal the incarnation of the dark titan Sargeras, but how much of this is a lie remains unknown.
Many powerful beings on Azeroth doubted the Guardian Aegwynn's defeat of Sargeras' avatar, but the fact that a massive Demons body slumbered within it was true, attracting the covetous eyes of countless beings.
This Demons body contains unimaginable power; whoever possesses this avatar may become a god.
Therefore, the Tomb of Sargeras attracted countless Demons from the Void, all seeking to unravel the secrets of this avatar.
There is never peace among Demons. Years of killing, bloodshed, and sacrifice have left the Tomb of Sargeras filled with Demons Corpses. The situation has finally reached a temporary balance, with several powerful Demons forces jointly occupying the Tomb of Sargeras and studying the secrets of the Avatar. The Burning Legion is just one of these forces.
Many years ago, Archimonde the Defiler, the second-in-command of the Burning Legion, also coveted the incarnation of the Tomb of Sargeras, but was forced to give up due to the overwhelming Demons power there, and instead marched on Mount Hyjal.
Aman'Thul's current strength is insufficient to conquer the Tomb of Sargeras.
But he wasn't in a hurry. If things went well, someone would help him complete it, and he could simply sit back and reap the benefits. He needed to utilize the Alliance and the Horde, using their sacrifices to pave his own path to success.
