-Mirkwood (Modern Mirkwood/After the war with Sauron 30 years later.)

Now residing in a magical elven castle nestled within the enchanting realm of Mirkwood, Kousei embraced his new life as Prince Arion with a sense of wonder and curiosity. The castle's graceful spires soared towards the heavens, adorned with intricate carvings that depicted the rich history of his people. Towering trees surrounded the castle, their canopies rustling with whispers of ancient secrets.

Within the castle's hallowed halls, Kousei discovered a world steeped in magic and tradition. He immersed himself in elven culture, learning the art of archery with Sir Legolas, and mastering the ethereal melodies of their enchanted instruments. It gave him happiness and contentment when he saw an elven piano in which he chose to keep in his room as a testament of his upbringing in the opposite Earth Realm. As a human, he had almost lost his hearing due to his trauma for losing his adopted mother but now, his senses, heightened by his elven heritage, allowed him to perceive the subtle energies that flowed through the very fabric of the realm. It was, as if, magic cured his depression. Even so, he also could feel that at the time the seal was removed, it was as if a thorn stuck in his heart suddenly vanished.

Now, Kousei's days were filled with exploration, as he ventured into the heart of Mirkwood Palace and Palace Forest, forging a connection with the natural world that surrounded him. He trained under the guidance of skilled mentors, lead by Sir Legolas, as hone his innate abilities and embracing the legacy of his royal lineage.

As time passed, Kousei's bond with his newfound family deepened, and he formed friendships with his elven kin. He found companionship in their timeless wisdom and shared in the laughter and camaraderie that echoed through the castle's corridors.

In the tranquil nights, Kousei often stood atop the castle's highest tower, gazing at the twinkling stars that adorned the velvety sky. The haunting melodies of the wind swept through the trees, carrying with them whispers of a destiny fulfilled and a realm finally at peace while a dark wizard, Ignatius wasn't anywhere to be seen after King Alexandria defeated him in a battle three years after Queen Arya brought him far from Middle Earth.

Kousei had embarked on a journey that led him from the world he had known into the realm of legends, where magic and wonder intertwined. As he looked out over the vast expanse of Mirkwood, he knew that he had found a new home, a place where his heart and soul truly belonged. It was also at this time that he had finally accepted and embraced his new name given and awarded by the Royal King and Queen of Mirkwood. Soon, he began to be called Prince Arion, son of King Alexandria by the Mirkwood Elven Council, all of the citizens of Mirkwood Kingdom, and beyond their lands.

..

Three years passed by so quickly for the young prince of Mirkwood, usually called as 'Kousei' by his closest elven and human peers. It was, of course, an uphill battle for him to adapt to his new surroundings after King Alexandria, his grand master and father returned him to his true realm and home.

Arima Kousei, now, more commonly known in Middle Earth as Prince Arion, smiled widely while walking through the majestic corridors of the Mirkwood Palace while he's with his grand master, Sir Legolas, who was once a prince of the Woodland Realm. Instead of becoming king of his land, he had chosen to be Prince Arion's teacher instead. Most of all, seeing the young prince grow into a strong and independent elven prince gave him such pride and happiness.

Arion's elven grace and Legolas' ethereal presence seemed to blend seamlessly, a testament to his successful integration into Middle Earth. It had been a long and arduous journey but he was very much grateful that Sir Legolas did his best to teach him the basics, survival in the magical realm, combat, and magic in his first three years on Middle Earth.

Everyone in the Elven Council and even in other kingdoms like Gondor knew that the Mirkwood Royal Couple brought the prince in another realm wherein there was no magic but instead, scientific technological progress, even so, if they look at him now, no one would be able to see the innocent boy from the Earth Realm as he had totally integrated himself in Middle Earth.

Reflecting upon the past three years, Prince Arion marveled at his journey of adaptation. At first, he had doubted his ability to fit into the magical realm even if his elven nature, image and look had been unsealed, but time had proven itself a remarkable ally. Gone were the initial days of uncertainty and awkwardness, replaced by a deep sense of belonging and connection to the elven way of life. Gone were the days of confusion and despair.

"Sir Legolas," Prince Arion looked beyond the palace windows and sighed. "It has been three years since I had arrived in this realm and I was now able to accept who I have become. Do you think my father would allow me to visit the villages of Mirkwood or even just its markets?"

Legolas gave him a wide, joyful smile as he saw the prince's curiousity and keenness to see the world he had stumbled on. For a boy like Kousei who came from Earth, he saw how difficult his adjustment was. The boy named Kousei who had transformed into Prince Arion had always talked about humans using electricity for light, and humans in the other Earth realm use cars or wheeled vehicles instead than horses or donkeys for transportation but there were none in Middle Earth at their first meeting. Unlike with his first months wherein he was just too clumsy and fearful, the prince had adjusted with his royal duties and studies. And with every princes in any realm, the prince now exude resilience and strength while his presence began to radiate regal authority. Clad in intricately woven robes adorned with delicate blue and gold threads, he ruled with a wisdom that belied his youthful appearance.

"You have totally changed into an Elven Prince now, Your Highness! It was always an honor to serve you," Legolas commented. "No one will ever know that you were once a boy from Terra Apenant Realm. I remember your old unaware self before but now, you've grown! Unlike when you were first here, your father would always worry about you."

"The boy I once was has to be shed and at the same time, I am forgetting who I once was. It worries me that if I meet my friends from Earth again, they wouldn't understand my position now," Prince Arion took a deep breath and sighed heavily. "Even so, I will forever still be that boy who loves music and piano. I never will be able to shed him totally away but as I totally immerse myself here, I can feel my memories from my days on Earth were fading away."

"That is normal, Your Highness," Legolas told him. "You're adapting in Middle Earth."

"That is right but I need some rest and away from the palace," Prince Arion responded, his hand resting on the hilt of sword, while his white robes and blue tunic flow elegantly. "Wasn't it time for me to finally see the outside of the palace walls?"

"Your Highness, as long as you are with me, your father won't worry about your well being. He trusts me with your welfare," Legolas said to him. "I'll escort you to the Victory Feast in Averen Market!" 

Prince Arion's heart swelled with a deep sense of goodness and unwavering loyalty, a feeling that brought a genuine smile to his face as he couldn't believe that for only three years, he'd transform from being a shy, innocent, fifteen years old pianist into an eighteen years old elven prince. "Thank you, Sir Legolas. I can't help but be thankful that my father chose you to be my teacher and my master. You have helped me adapt in a world so different from whence I came from."
