Queen Azshara's voice echoed on both sides of the Portal, audible to both the Highborne and the soldiers of the Burning Legion:
"Legion, stay away from Azeroth, and never again covet Azeroth, for I am the Queen. I can resolve the threat of the Old Gods, and I can withstand attacks from beyond the heavens. If you agree, I will personally offer you the magic of Fel Compression, my Headmistress."
Archimonde felt humiliated to be reprimanded by his own student in public.
Queen Azshara wanted this effect, lest the cunning Archimonde change his mind.
Archimonde cautiously observed Queen Azshara. Sargeras Void Academy was full of talented individuals, including many geniuses, but those who could defy authority and escape the Legion's control like Azshara were extremely rare.
"Azshara, you are the Queen of the Night Elves, the Guardian of Azeroth. I want to know if you have the ability," Archimonde said, raising his massive tail and a slight smile playing on his lips.
"You must prove your ability in this competition; consider it an exam I'm personally administering."
"It's a great honor."
The illusion of Queen Azshara vanished, and a streak of light rose from the direction of Azshara City, flew into the Portal, and floated in front of Archimonde. Queen Azshara's true form was hidden inside a golden sphere.
"Headmaster Archimonde, shall we begin? No one has challenged me in all these years. The newcomers are still growing, and there are no worthy opponents. How lonely it is to Invincible! I crave a thoroughly enjoyable battle."
"Haha, seeing my students grow to this level makes me, as the principal, especially gratified," Archimonde said insincerely, revealing a sly smile.
"To prevent our battle from affecting innocent people, let's fight in the Arena of the Twisting Nether."
Each leader of the Burning Legion has their own Twisting Nether Arena, which is essentially their home turf, giving them a huge advantage. Queen Azshara simply smiled faintly:
"No problem."
Archimonde nodded, and the two disappeared simultaneously.
Robbie quickly activated the Eye of C'Thun and followed Archimonde's massive body into the Twisting Nether. The Twisting Nether had a spatial passage connecting it to the real world, and Robbie succeeded on his first try.
The dark starry sky was filled with twinkling stars. At the top of the sky floated a green Fel sphere, the source of Archimonde's Fel. In this space, his power was virtually inexhaustible.
Archimonde was smug, with an expression of certainty and victory in his grasp.
"Azshara, I must teach you one last lesson: never enter your opponent's Twisting Nether lightly. I am the master of this space. Here, I can defeat far more powerful opponents. You miscalculated, Azshara. Fortunately, I am merciful. If you surrender the Fel Compression Magic and allow the Legion to garrison Azeroth, I will let you leave. You can go back to being your queen."
Azshara's body was hidden within the golden sphere; her voice was calm and serene.
"Archimonde, let our battle begin. This fight is meaningless if it's not within your Twisting Nether. I look forward to seeing what surprises you can bring me, otherwise it'll be too boring."
"It's truly pitiful. In my life, I've seen far too many arrogant juniors like you, but they're all dead."
Archimonde stretched out his right hand toward the Fel in the sky. The Fel sphere erupted, and green Fel formed a net-like structure that covered the entire space, like a giant shield.
"This is my space, my domain, I rule over everything."
A green rain of Fel descended from the sky, like a torrential downpour, covering every space.
The power of Fel is altering the structure of space; the first thing to change is the gravity of space.
Gravity increases steadily, ten times, twenty times, thirty times, fifty times, five hundred times.
Archimonde's massive body groaned under the strain, a sound born of the pressure between his joints. Despite his obvious discomfort, Archimonde still managed a triumphant laugh.
"Azshara, your magic is powerful, but it can't overcome the weakness of your body. Your flesh and blood are so vulnerable. My body is made of the strongest materials, with flesh and blood making up only a small part. Supported by powerful magic, it's indestructible and can withstand gravity five hundred times stronger than normal. Haha, you're already overwhelmed, aren't you? If you can't take it anymore, beg for mercy, and I'll gladly grant your wish."
A languid voice emanated from within the golden sphere; Queen Azshara seemed quite reluctant.
"If that's all there is to it, our battle could be over. You can continue to increase the gravity; it won't affect me at all."
"You, this is impossible, the fragile body of a mere Night Elf."
Archimonde was filled with shock, and then he increased the pressure on the space again.
High temperature, high pressure, and constantly changing spatial laws caused countless energy particles to fly out. In the end, even Archimonde's body could not withstand it. Archimonde looked suspiciously at the golden sphere covering Queen Azshara.
Archimonde recognized that this was merely a simple disguise spell with no defensive capabilities. Queen Azshara had actually withstood the harsh spatial environment with her bare body; could her physique be even stronger than his own?
Unable to contain his curiosity any longer, Archimonde stepped forward, a green light appearing in his hand, and slapped it towards the Queen's golden sphere.
The golden sphere was as fragile as a bubble, revealing Queen Azshara's true nature.
The queen had completely lost her Night Elf form; her lower body consisted of three enormous tentacles, her four arms were covered in thick scales, and an Evil eyeball sat atop her forehead.
"The Power of the Old Gods —you actually implanted the flesh and blood of the Old Gods into your own body."
It must be said that the Void Civilization is stronger than the Burning Legion.
The Old Gods could traverse the universe in their physical bodies and adapt to all kinds of harsh environments, something the Burning Legion could not match. Sargeras's development of Fel was very limited and could not compare to the countless years of inheritance of the Void.
"Principal Archimonde, you're too old for this era."
Azshara said calmly:
"I imagine you must be wondering why Azeroth is so full of secrets. It's quite simple: it's merely our development and application of the Old Gods' power. You, on the other hand, only believe in Fel. Over countless years, your Eredar Demons have hardly changed. The universe is cruel; civilization either progresses or regresses. You have failed Sargeras's expectations."
Robbie, wielding the Eye of C'Thun Robbie, had a sudden thought, and Queen Azshara's deliberate exposure of her Old Gods form was actually quite meaningful. Archimonde was unaware of how the Night Elves had deciphered the secrets of N'Zoth's spirit, which was bound to deeply fascinate the Burning Legion with the secrets of Azeroth.
Queen Azshara took the initiative to dispel Archimonde's doubts.
"The Power of the Old Gods? You're a complete madman!"
Archimonde gritted his teeth, for the Burning Legion relied too heavily on Fel and could not possibly wield the power of the Old Gods.
"Azshara, surrender your Fel Compression Magic, or the Burning Legion will crush you."
Archimonde revealed his true intentions and finally unleashed his last move: he opened hundreds of Portals, connecting the various worlds occupied by the Legion, attempting to wear down Queen Azshara with a massive Legion soldiers.
