In fact, Cenarius initially refused the order.
After losing the Oak Axe, White Stag Malorne was in a bad mood. After questioning a series of witnesses, she learned that it was made by a failed experiment that resembled Cenarius.
The problem is that the test subject is already dead; Malorne executed him himself the night before.
Malorne sensed something was wrong. He didn't understand this resurrection power, so he went to investigate the whereabouts of the Oak Axe himself.
So he summoned Cenarius, whose only remaining soul was left, and had him lead the Red Dragon Krasus, Rhonin, the Orcs Broxigar, Malfurion on a tour of the Emerald Dream, specifically instructing them to observe the Magic City of Azshara through the Emerald Dream.
Cenarius was in a particularly bad mood, especially when he saw Broxigar riding his body, walking around smugly, showing off in such a deliberate way. Cenarius was burning with rage.
But he dared not disobey the orders of White Stag Malorne, and could only endure it.
A deeply depressed Cenarius led the way, passing through one green Portal after another.
Cenarius, disheartened and listless, said:
"Queen Azshara is a scourge to the Night Elves. Her Evil reign has caused countless Night Elves to suffer, and has even threatened the safety of the Emerald Dream. You see, every tree here possesses eternal wisdom; they understand Queen Azshara's Evil and therefore hide within the Emerald Dream."
Looking at Cenarius's pitiful soul and body, Rhonin felt that his tone was not convincing at all.
Cenarius, realizing his tone was off, and focused, secretly glaring at Broxigar before speaking in a measured, inflection tone:
"The power of Elune, protects us. Only we, the Night Elf race of Mount Hyjal, can enjoy a peaceful and prosperous life. To avoid causing panic, we have been keeping it a secret from the outside world, not telling them about the suffering the Night Elves endure. They are tormented under the dual oppression of the Burning Legion and Queen Azshara."
The forest parted to the sides, and the surrounding scenery became increasingly ethereal and unreal. Driven by instinct, the group flew into the elusive dreamscape. The world turned into a jewel-green hue, growing ever more hazy and ethereal, with only the sounds in their ears remaining clear.
"We are now in the Emerald Dream, between the mortal world and slumber. I will take you to the magical city of Azshara, to witness firsthand the suffering it has endured. The time has come; the Night Elves of Mount Hyjal are gathering their strength and will surely overthrow Queen Azshara's Evil rule, winning great freedom."
Before Cenarius appeared a vast lake, its waters as black as ink, waves crashing against the shore, and strange rays of light radiating from its center, where a Maelstrom and a portal to space were located.
Magically colored lake water churns up from the bottom of the lake, keeping the giant Portal running. Behind the Portal, a world of Lava and Flame can be clearly seen.
Cenarius looked sorrowful and said sympathetically:
"The Burning Legion destroyed a world, and now their target is the Azeroth Continent. The Evil Queen Azshara has colluded with the Burning Legion, and their Demons armies have already entered Azshara."
Guided by Cenarius, after passing through a dreamlike, hazy shadow, the Magic City of Azshara, named after Queen Azshara, now appeared before the four of them.
Cenarius said with great sorrow:
"Azshara, the City of Magic, a symbol of prosperity and abundance, the most beautiful jewel of the Kaldorei Empire, but look at what it has become since Queen Azshara went mad."
Krasus, Rhonin, Broxigar, Malfurion looked down upon the Azshara City.
A ruin filled with rubble, the central area was in complete disarray, with the Burning Legion's Fel towers and towering Fel Forge everywhere. The Burning Legion's forces had filled the entire city, including the vicinity of the Queen's palace.
Rhonin saw the trembling Night Elves, ragged and weak, scavenging for food among the rubble and garbage like filthy rats. Legion soldiers frequently chased them away, or even executed them on the spot.
Inside the Legion's massive Fel Forge, tens of thousands of Night Elves wailed in agony. Their pitiful cries and agonizing torment fueled the Fel Furnace, and a green Fel aura permeated the entire sky above Azshara.
In stark contrast, within Queen Azshara's incredibly luxurious palace, beautiful maids dressed in revealing attire flitted through the banquet like butterflies, carrying trays of food and wine.
The nobles indulged in nightly revelry and excessive drinking, turning a blind eye to the suffering outside.
"How could this be?" Rhonin couldn't believe his eyes.
"No, no, my poor brethren!" Malfurion knelt helplessly on the ground, tilting his head back and raising his hands in prayer to Moon Goddess, the moon goddess. "Great Elune, please save my wretched people."
Cenarius gritted his teeth, his voice filled with hatred, and said, "The Night Elves are suffering agonizing pain. Queen Azshara is plotting to destroy the Azeroth. We must fight against her, even at the cost of our lives."
"Destroy Azeroth?" Rhonin had a familiar feeling; this wasn't a phrase Thrall, the Savior, often uttered. A hint of doubt arose in his heart as he looked at Broxigar.
"But this Emissary vowed to help the Night Elves cooperate with the Burning Legion and gain the power of Fel. Isn't the Burning Legion the enemy of the Night Elves? Why should we cooperate with the enemy?"
Broxigar grinned, revealing Evil smile, and said nothing, only looking at Cenarius.
Cenarius also taken aback. He didn't know how to explain it and hurriedly looked at Malfurion.
Malfurion chuckled awkwardly and said tactfully, "In fact, the Burning Legion is our closest ally, capable of helping us fight against the Evil Queen Azshara. We must unite the Legion's strength."
Rhonin grew increasingly confused, looking at Cenarius with bewilderment. This annoyed Cenarius, who found Rhonin incredibly rude.
Krasus subtly tugged at Rhonin's sleeve and winked at him. The Red Dragon had lived for countless years; what hadn't he seen? He knew what it meant to "see through things but not say them out loud."
Broxigar laughed loudly, his Orcs face contorted with rage, and said, "Night Elves are a lowly and contemptible race. Tremble before the great Legion! You are fit only to be slaves and livestock. Ignorance is the mark of an inferior race."
Cenarius and Malfurion were both quite embarrassed. They dared not oppose the great Emissary, nor could they explain themselves to Krasus and Rhonin. Fortunately, Krasus was smooth enough to step in and smooth things over:
"The Legion is not a monolithic entity; it is divided into many factions. Those who aid Queen Azshara are the Evil faction, Emissary helped unite us into the friendly faction. Rhonin, do you see? This is not contradictory."
Malfurion nodded quickly. "That's right, that's right, that's exactly what the great divine Emissary wanted to express."
What is Justice and Evil? In the end, it all comes down to self-interest.
Rhonin shook his head and said nothing more. He had come to a profound understanding that there was no distinction between good and evil in the world, only victory and defeat, and that he should stand on the side of victory.
From the perspective of the world ten thousand years in the future, the victor is clearly the Elune.
So the choice isn't difficult.
