Tempest Keep, the interdimensional spaceship used by the Naaru for travel throughout the greater universe.
Robbie, Krasus, Kael'thas teleported to the entrance of Tempest Keep, marveling at the grandeur of the spaceship.
A remarkable achievement of Naaru Crystal Technology, the entire spaceship resembles an inverted amethyst mountain.
Upon entering Tempest Keep, they found all the Blood Elves unconscious.
The Naaru, or possibly other manipulators behind the scenes, relinquished control of the Blood Elves after Kael'thas awoke.
Kael'thas clearly saw that many Blood Elves were holding weapons.
Kael'thas probably returned too quickly and didn't have time to stop them from killing each other.
Having expelled the Scarlet Holy Light from the Blood Elves, Kael'thas gathered his people together.
Apart from the Illidari Council of the Black Temple, almost all of Kael'thas's subordinates were here.
The core of the force consists of four personal advisors, the Grand Astromancer Solarian, an Ethereal Mech, and the Phoenix summoned by Kael'thas.
Thinking of the Destiny that awaited him, Kael'thas couldn't help but sigh.
The Blood Elves were unable to control Tempest Keep, could not find the weapons and control systems, and were unable to move the mountain-like ship.
It is a fortress in the sky, a mountain peak that is suspended thousands of feet in the air and cannot be moved.
It is indestructible; it is impossible to destroy it.
Krasus suggested, "Why not abandon Tempest Keep, lead our people into the Black Temple, and join forces with Illidan?"
However, Kael'thas did not think so.
"Tempest Keep is our last chance Blood Elves. With this Blood Elf, we can venture into space and find a new home."
Krasus scoffed, "You think you can handle the Naaru's technology? Not that I look down on the Blood Elves, but your civilization is at least a million years behind the Naaru's."
Kael'thas had already planned this. "I've heard there's Consortium in Nagrand, comprised of Ethereal involved in smuggling, trade, or theft. Perhaps they have a way."
Robbie suggested, "Why go to such lengths when the Burning Legion has Forge Camp in Netherstorm? Kidnapping a few Legion Engineers would be a good way to get to the Army of the Light best."
"And the Draenei," Krasus added. "Velen's ability to move part of Exodar from Tempest Keep proves the Draenei have this technology."
Without hesitation, Kael'thas dispatched three groups of his most trusted confidants to the Nagrand Consortium camp, the Netherstorm Forge Camp, and to search for the reclusive Draenei.
However, the biggest challenge facing Kael'thas was the defense of Tempest Keep.
While Kael'thas was busy with his own affairs, Robbie and Krasus discussed things privately.
"According to historical records, Tempest Keep will definitely fall. Are we really going to help Kael'thas?" Krasus asked anxiously.
Robbie smiled faintly, "Don't worry, history is full of lies. The Naaru, for the sake of the Army of the Light's reputation, are very likely to fabricate history. I'd like to see how the Shattrath Alliance conquers Tempest Keep."
Kael'thas didn't bring many Blood Elves with him, and after Voren'thal's betrayal, only about ten thousand remained.
These 10,000 people also had to defend the Botanica, the Mechanar, and the Arcatraz, which put them in a very difficult position.
But its greatest advantage is that Tempest Keep is located in mid-air, with an indestructible outer shell, so enemies can only attack from the front gate, making it easy to defend and difficult to attack.
If absolutely necessary, the spaceship's doors will be tightly closed.
It would be virtually impossible for a backward civilization from Outland to destroy Tempest Keep.
Therefore, Kael'thas had ample confidence in defending Tempest Keep.
The City of Holy Light, Sha'tar, has five major factions.
The highest-ranking group is the Naaru, the supreme rulers of Sha'tar, equivalent to royalty.
Then there are the Aldor and the Scryers, who are hostile to each other; the Sha'tar Skyguard, who are responsible for the city's defense; and finally, the Lower City, which have the largest population.
After Kael'thas broke free from his puppet form, the radiance of the Naaru A'dal illuminated the entire city of Shattrath.
The Scryers leader, the Prophet Voren'thal, straightened his clothes, his purple robe spotless, and headed to the Holy Light Plaza in the city center to listen to A'dal's teachings.
Prophet Voren'thal was Kael'thas's most outstanding strategist and the elder Kael'thas relied on most, who obeyed his every command.
It was Voren'thal's idea to defect to Illidan and enter Outland.
Two years ago, twenty-four years after the Dark Portal, the Naaru sailed into Outland from Tempest Keep and rebuilt Shattrath City on its ruins.
Voren'thal suggested that they take advantage of the Naaru's unstable foothold and try to capture the city.
Kael'thas hesitated because he didn't want to offend the Army of the Light, but ultimately agreed to Voren'thal's request.
The two had a clear division of labor: Kael'thas would feign an attack on Tempest Keep, while Voren'thal would probe Sha'tar's defenses.
Unexpectedly, Voren'thal led his men to defect to the Naaru Legion, infuriating Kael'thas and causing the Blood Elves to waver.
Afterwards, Kael'thas and his people became puppets, having no time to deal with this the Betrayer.
Above the Holy Light Plaza, Naru'adar shone as brightly as the sun.
Voren'thal led his men to the center of the square, where a group of Draenei had arrived before them.
Aldor's leader, High Priestess Ishanah, turned around and sneered:
"Look who's here! The Betrayer Voren'thal, your Prince has awakened. I wonder what you intend to do?"
The Aldor and the Scryers are bitter enemies because Kael'thas's men once killed Draenei.
Interestingly, the Aldor showed remarkable tolerance towards the Orcs nearly wiped out the Draenei; Ishanah practically knelt down and licked Thrall's toes every time she saw Thrall.
Voren'thal scoffed, "By the Holy Light, my loyalty to Shattrath City is unwavering. Do you really think the Orcs will participate in the Battle of Tempest Keep?"
At the mention of Orcs, Ishanah's face lit up with a look of adoration. "Orcs are great and kind, I'd be willing to be Thrall's dog."
"Hopeless piece of trash," Voren'thal sneered.
With most of the people present, A'dal slowly descended, stopping above their heads and retrieving the scattered Naaru Shard.
In the Holy Light Plaza, everyone knelt on the ground, submitting to the Sha'tar King.
"Kael'thas has broken free of his restraints." A'dal's voice was calm and warm. "We must retake Tempest Keep. What suggestions do you have?"
Air Force Captain Dur'in, belonging to the Sha'tar Skyguard, said devoutly, "The Skyguard is ready. We have used the Nether Rays as bait to cultivate a large number of adventurers, who will become the main force in the attack on Tempest Keep."
High Priestess Ishanah retorted, "The Aldor have recruited a large number of adventurers, ready to sacrifice themselves for Sha'tar at any time."
A'dal's voice came through. "Ishanah, the Aldor's loyalty is beyond question. Your mission is to fight against the Burning Legion. Voren'thal, I want you to lead the Battle of Tempest Keep."
Voren'thal said respectfully, "Although Kael'thas is a fool, his four advisors are all resourceful. It won't be easy for the Scryers to win, and we also need to be wary of reinforcements from the Black Temple."
Ishanah immediately seized the opportunity to sneer under her breath, "Scryers are a bunch of incompetent good-for-nothings."
A'dal for a moment. "Voren'thal, do you have a complete plan?"
Voren'thal replied, "Yes, my plan is to unite the forces of the Alliance and the Horde in Azeroth."
