I am an Alien in another reality.

In the Ravenclaw common room, Alex sat waiting for Luna. He gave a mental suggestion to the fox, urging it to run to the common room so Luna would come out. After a while, Alex saw Luna in her pajamas, running after the little fox.

"Hey Luna, good evening," Alex greeted.

"Hi Alex, why are you awake?" Luna replied, slightly out of breath.

"Come, sit beside me. I have something to ask you," Alex gestured to the space next to him.

Luna came over and sat, looking at him curiously.

"Wanna come with me? To travel?" Alex asked softly, his gaze steady.

"Like Harry? I'd love to," Luna replied without hesitation.

"Sort of, but different. Let's go this weekend."

"Okay," Luna said, puzzled but intrigued.

They talked for a while before returning to their dormitories. Alex looked around his familiar room but felt nothing. Perhaps the only attachment he had to this world now was Luna. He still valued this world and wanted to perfect it, even if achieving that meant inducing war. For Alex, the end justified the means.

Three days later, Alex held Luna's hand as they traveled through worlds. Arriving at the Moors, Luna's eyes sparkled with excitement as she took in the lush forest and the magical creatures frolicking nearby.

"Look how excited you are," Alex chuckled, handing her a pouch of energy beads. "These will help you befriend even the most cautious creatures."

"Thank you, Alex!" Luna beamed, hurrying toward a group of water fairies playing in a stream. She crouched low, speaking softly as she stretched out her hand to offer the beads.

Alex smiled at her enthusiasm before turning to follow a faint presence he recognized. He emerged into a clearing where Eira and other fey children were riding small unicorns. As if sensing his arrival, Eira stopped and turned toward him. Her eyes lit up with joy as she leaped into the air, her delicate wings fluttering as she dove into his arms.

"I missed you, Papa," she said softly, her voice like wind chimes.

Alex stroked her hair, cradling her gently. "Papa missed you too."

Moments later, Maleficent arrived, folding her wings as she approached. Her sharp eyes softened at the sight of Alex holding Eira.

Still carrying Eira, Alex greeted Maleficent and explained the purpose of his visit, inviting them both to his wedding.

"It would be an honor. Don't worry. We can depart anytime," Maleficent replied without hesitation. She had met Arwen before and expected this day to come, though the idea of attending a wedding in another world intrigued her.

Alex then introduced Luna to them, explaining her origin and background. Eira's eyes sparkled with curiosity as she eagerly dragged Luna to meet her friends and introduce the animals she had befriended.

By evening, Eira and Luna returned, their faces glowing with happiness. Reuniting with Alex and Maleficent, they prepared for the journey to Middle Earth. With a soft glow of magic, they teleported to Middle Earth.

Arriving at Rivendell, they were guided by an elf guard to a pavilion where Elrond and Arwen were discussing something over tea. When Arwen saw Alex, she jumped from her seat and threw herself into Alex's arms like a little girl, forgetting for a moment that others were watching. With a cough from Elrond, Arwen returned to her senses, her face flushed with embarrassment as she greeted everyone formally.

Alex introduced everyone to Elrond without hiding anything, seeing no point in concealing the truth from his future father-in-law. Soon, their conversation turned to the venue for the wedding.

"Actually, I've got that covered. We need to figure out who the marriage officiant will be," Alex expressed.

"How about Gandalf?" Elrond suggested.

"Oh, I've got a better idea," Alex grinned.

Everyone looked incredulous as specks of light began to gather, forming a figure of radiant energy with indistinguishable features. The elven city hummed with solemnity, and everyone who sensed the presence knelt in reverence, except for Alex, Arwen, and those from outside Middle Earth.

"Father," Elrond called out to the figure reverently.

"What do you say, Your Excellency Eru?" Alex addressed the figure. Arwen, shocked, moved to kneel, but Alex held her firmly, preventing her from doing so.

"If it's just for formality, then I don't object. Also, after this, will you stay away from my world? I have to cope with every whimsy you bring," an ethereal, androgynous voice responded as Eru addressed Alex.

"Sure thing," Alex replied with a smile, glancing at Arwen.

The presence of Eru brought a solemn yet profound energy to the gathering, leaving an unforgettable mark on the preparations for the wedding.

Meanwhile, in Westeros, while Daenerys continues Alex's conquest; the construction of Alex's domain progressed rapidly. 

The Bloody Gate was replaced with two towering adamantium statues holding flaming torches on either side of a massive, solid black adamantium gate.

Thick and heavy, the gate could only be opened with magic, serving as the grand entrance to the main road leading to Alex's castle. The road itself was paved with polished granite slabs, exuding strength and grandeur.

Lining both sides of the main road were buildings featuring Classical architectural designs, columns, arches, and decorative friezes. The first structures housed guard posts to handle entry registration and security appraisal. Further along were shops, businesses, and apartments for merchants and visitors.

Closer to the castle gates stood barracks and residences for Alex's heavenly soldiers. The final structure before the castle is a bathhouse and changing station, where visitors were required to cleanse and dress appropriately before entering the palace grounds.

Rich or poor, all citizens were mandated to bathe and change into proper palace attire suited to their status before passing through the gates of Alex's domain, reinforcing order, respect, and the grandeur of his rule.

The throne room reflects luxury. A massive jade door opened to a plush red carpet that led to a throne made of crystal with a pale glow.

The pillars were adorned with intricate carvings, filigrees made of gold, and sparkling gemstones. Black banners hung from them, embroidered with a crescent moon and a half-golden, half-silver tree.

Golden sconces with glowing crystals decorated the walls on both sides, ensuring no shadow was cast when entering the hall. A giant chandelier filled with glowing white gems hung above the center of the hall, casting a soft, bright light.

Light filtered through high windows made of glass, illuminating a black dragon with the throne between its paws. The dragon appeared motionless, its eyes closed, but the glint of its scales indicated it was alive.

Fluffy white clouds and mist surrounded the throne, making it appear to float and obscuring the dragon's figure. On the throne, Alex's avatar sat with one hand on his cheek looking at Sansa kneeling below.
