The crowd cheered when they were presented with the heir of Stormwind. After the harem had done their admiring, close friends and confidantes came in to give their congratulations, then high nobles and other officials and finally the royal couple had gone to the city-facing balcony to show the child to the common people. All of it had taken several hours, but Anduin didn't mind. The whole world was to see his son.
The cheers, however, were cut short when a giant tear opened up in the sky. A blue portal, above a kilometre wide, opened up from above and a grey, upside down tower slowly lowered itself out of a ghastly grey and verdant green landscape. For a moment, Anduin was confused, but then he recognized Deadwind Pass. It had only been a few days, but the green dragons must have already made first successes in re-fertilizing the area. The tower that slowly descended was Karazhan in its entirety.
With the flair of arcane purple, Khadgar and Modera appeared next to him. "My congratulations to your first child, High King," the old arch mage greeted. "What a lucky timing that our ritual is finished just in time for a present."
"What are you doing?" Anduin wanted to know, furrowing his eyebrows at the gargantuan construction hanging over Stormwind Keep. The two structures were of similar size and he felt uncomfortable at the thought of one falling onto the other.
"You wanted the Dusk Pond here in Stormwind and my old teacher thought he may as well give you a bit more than that," Khadgar explained. "Karazhan wasn't doing much good for the world where it stood. Don't worry, I've inspected everything about this and deemed it perfectly safe!"
Just as he said that, the gargantuan tower began to fall apart. Brick for brick loosened and fell towards Stormwind Keep. Putting his trust in the arch mage and the Last Guardian, he watched as the falling bricks lost their dull grey colour. Assuming royal purple, glowing silver, and shining gold, the bricks spread out. At the same time, Stormwind Keep began to be pulled apart, its many small towers, bridges and fortifications being dissected like a simple engineering project. The stones of Karazhan laid themselves into the resulting gaps.
As Karazhan was dissolved, Anduin's palace grew into a structure beyond magnificence. Massive crystal pylons, the intricate depth of Slaveforge, the Summerwind Nexus and the other magical wonders of Dalaran, the new, massive cathedral and the growing of the other districts had all contributed to leaving the seat of power to look oddly small given its de-facto importance. What had once been the marble-white fortress overlooking the city had been degraded to a second-rate landmark.
Now it was being reconstructed by the might of most of the greatest mages of the last century. Marble white blended with purple, silver and gold to create towers small and large. The surrounding mountains were flattened by magical force to make more room for the self-placing bricks, as they expanded the walls. The fortress walls became taller and thicker than before, surrounding a keep of great splendour. The bricks didn't just randomly insert themselves, but created large patterns through the walls. Windows were rearranged and transformed, roofs for towers and stretches of living quarters tiled in dark red and circular courtyards arranged to give room to parks inside the absolutely gargantuan palace that was created.
A particular large courtyard at the very centre of the grounds became the resting place of the Dusk Pond. The well of Fel power hovered, confined by its pool, down as one into its new home. It was one of the last elements to settle, only followed by a sudden torrent of blue and purple energies that cascaded down through the now closing portal. They seeped into the stones, giving them an arcane lustre, and into the very ground. The balcony attached itself to the large tower facing the city, right above the new entrance.
The reconstruction was complete and Medivh appeared next to Anduin. "Greetings," the ghost raised his hand as if nothing of note had happened. "I hope you approve of my gift to you."
"I'm not honestly not quite sure what just happened, outside of the obvious," the High King responded, looking over what he could still see of the palace walls from his current perspective. The keep had doubled in terms of the material visibly used for it, but the surface it actually covered had more than tripled. Its highest spires were now almost as tall as the mountain of Slaveforge. From every part of the city, Stormwind Keep could be seen.
"I made your home the greatest and most secure place currently on Azeroth," Medivh explained. "A fortress of unparalleled beauty, power and size. You may think that what you see is already massive, but thanks to carrying over Karazhan's unique properties, you will find that this palace is even larger on the inside than it could conceivably be judging from the outside. Every stone is enchanted and power will never be an issue. The leyline I shackled to my mage tower has been pulled along with its essence, leaving it underneath Stormwind."
Jaina furrowed her eyebrows. "Arcane manipulation of such a scale is..."
"...absolutely possible if you're me," the Last Guardian dismissed even the beginning of a complaint.
"Just believe him, it makes things quicker," Khadgar stated. "That aside, things that happen around Anduin are hardly deemed impossible anymore, are they?"
"Doesn't this mean we will have to deal with all of the dark things still lurking in your tower, Medivh?" Anduin wanted to know, putting his arms protectively around his first wife and son. "The ghosts, demons and other beasts?"
"Do not worry, with the sealing of the Dusk Pond, the majority of these problems are withering. Those who haven't fled will die in a short while. You may find some dark chambers filled with an absurd amount of spiderwebs, but that will be the worst of it," Medivh assured. "I will personally make sure these new halls are secure. For as long as fragments of my spirit remain, I will guard it... which effectively makes me the eternal watcher, it seems. Guardian of Stormwind, a title more accurate to the times than Guardian of Tirisfal."
