Two months had passed since Ariel's triumphant first year at Hogwarts. The warm summer sun painted Minerva McGonagall's sprawling estate with shades of gold and amber. It was within these picturesque grounds that Ariel found himself immersed in a new pursuit—the art of duelling. The tranquil gardens provided the perfect backdrop for mastering the dance of magical combat.

Under the watchful eye of Professor McGonagall, Ariel's lessons in duelling commenced. Their training began with the fundamentals—wand movements, defensive spells, and the intricate choreography of countering hexes and jinxes. Ariel's innate prowess allowed him to grasp these essentials with an almost uncanny speed, his reflexes sharp and his movements elegant.

Yet, it was his innovative approach that set him apart. In duelling scenarios, Ariel wove spells together in unexpected combinations, creating dazzling displays of magic that left opponents and onlookers alike in awe. His tactics were unpredictable, a testament to his ability to adapt and improvise.

During one training session, as his wand whirled through the air, Ariel transfigured a thin stream of water into a swirling vortex. With a swift gesture, he redirected the vortex to shield him from an oncoming curse, the water's ethereal beauty deflecting the attack with a mesmerizing dance. The transfigured water then cascaded into a torrent that surged toward his opponent, capturing them in a watery embrace. It was a blend of transfiguration and duelling that showcased his unassailable mastery.

Minerva McGonagall's stern countenance transformed into an impressed smile as she observed his performance. "You wield magic like a maestro, Ariel. This creativity is your greatest asset."

But with the arrival of autumn, a new figure stepped into Ariel's journey—the formidable Albus Dumbledore. His wisdom and intuition infused Ariel's training with a new dimension, pushing his boundaries even further.

Dumbledore's lessons were akin to unveiling hidden realms within Ariel's magic. He taught Ariel to listen to the whispers of the universe, to feel the currents of magic that flowed through his veins. They explored the intricacies of spell craft, dissecting the origins of each incantation, and unravelling the possibilities that lay within. Ariel's magic became an extension of his very being, an embodiment of his thoughts and will.

As days turned into nights and nights into days, the training montage spanned the summer. Ariel's progress was a testament to his dedication, his proficiency now marked by an unparalleled understanding of magic's intricacies. He had become a duelling prodigy, his very presence commanding attention.

Amidst his training, Ariel's evenings were often accompanied by the ethereal strains of his singing—a hobby that had woven itself into the fabric of his life. His voice was a symphony of beauty and emotion, a melody that resonated through the estate and beyond. Magical creatures of all kinds would gather, drawn by the enchanting harmonies—a testament to his affinity with the natural world.

In the Three Broomsticks Inn, the warm aroma of butterbeer filled the air as Ariel's melodious voice filled the room. His singing was not just a skill—it was enchantment. With each note, he cast a spell on the hearts of those present, his voice weaving a tapestry of emotions that resonated deep within. Even Madam Rosmerta herself couldn't help but pause to listen, her eyes transfixed on Ariel as if under a bewitching charm.

Ariel's eyes, like twin orbs of intense power, held a depth that seemed to pierce the very fabric of reality. They radiated a commanding presence, drawing others into his orbit with a magnetic pull. In their depths, a universe of magic and mystery resided—an embodiment of his enigmatic and formidable nature.

As the sun dipped below the horizon, Ariel's heart beat in rhythm with the magic around him. The International Youth Duelling Competition loomed on the horizon, an event that promised to unveil a new chapter in his journey—one that would carry him beyond the serene estate and into the wider world of magic.

The days were filled not only with training but also camaraderie. A trip to Hogsmeade village brought moments of laughter and bonding. Ariel and Minerva explored the quaint shops, enjoying the company of familiar faces and meeting new ones. In the Three Broomsticks, they shared stories with Madam Rosmerta, a warm and welcoming presence who marvelled at Ariel's singing prowess. It was a day that infused a sense of unity and belonging into Ariel's journey.
