Hadrian Bael found himself standing in a vast, unfamiliar hall, its ceiling seemingly enchanted to reflect the night sky above. Hundreds of eyes were fixed upon him, a sea of unfamiliar faces wearing expressions of confusion and curiosity. At the far end of the hall, seated at a long table, was an elderly man with a long silver beard and half-moon spectacles, his blue eyes twinkling with interest.

The old man rose from his seat, his vibrant purple robes swishing as he approached Hadrian. "Welcome, young man," he said, his voice gentle yet carrying across the silent hall. "I am Albus Dumbledore, Headmaster of Hogwarts School of Witchcraft and Wizardry. Might I ask who you are?"

Hadrian's posture remained straight and confident, despite his inner confusion. He had no idea where he was or how he'd gotten there, but years of training had taught him to remain composed in unexpected situations. "I am Hadrian Bael," he replied, his voice clear and steady. "I'm afraid I don't know where I am or how I came to be here."

Dumbledore's eyebrows rose slightly. "Interesting," he murmured. "Tell me, Hadrian, does the name Harry Potter mean anything to you?"

A flicker of recognition passed through Hadrian's eyes. "That... was my name once, a long time ago. But I haven't been called that for years. I am Hadrian Bael now, a proud member of the House of Bael."

The hall erupted in whispers at this revelation, but Dumbledore silenced them with a raised hand. "I see," he said, his voice tinged with curiosity. "And how did this change come about, if I may ask?"

Hadrian's lips curved into a slight smile. "It's a complex story, sir. One that involves a blood adoption ritual. I understand such magic is considered illegal here in Britain, but where I come from, it's a respected ritual."

Dumbledore's eyes widened at this revelation. "Blood adoption? That is indeed powerful magic, my boy. And you're right, it is illegal here. But let's set that aside for now. We should discuss why you've been brought here. You see, your name – or rather, the name Harry Potter – has just emerged from the Goblet of Fire, naming you as a champion in the Triwizard Tournament."

"Triwizard Tournament?" Hadrian repeated, his brow furrowing slightly. "I'm afraid I'm not familiar with it."

As Dumbledore explained the nature of the tournament and the magical binding contract, Hadrian listened intently, his mind already working through the implications. When the Headmaster finished, Hadrian nodded slowly, a glimmer of understanding in his eyes.

"I appreciate your explanation, Headmaster Dumbledore," Hadrian said, his voice calm and measured. "While I understand the gravity of the situation, I believe there might be a misunderstanding regarding the binding nature of this contract."

Dumbledore's eyes widened slightly. "Oh? How so, my boy?"

Hadrian straightened his shoulders, his gaze steady. "As I mentioned, I underwent a blood adoption ritual. I am, in every magical and legal sense, a Bael. The name Harry Potter no longer holds any power over me. As such, I don't believe this contract can be binding for me."

A murmur of surprise rippled through the Great Hall. Dumbledore stroked his beard thoughtfully, his blue eyes studying Hadrian with renewed interest.

"That is indeed a fascinating development," the old wizard said. "If what you say is true, it could indeed nullify the contract. However, we must be certain. The consequences of breaking a magically binding contract can be severe."

Hadrian nodded, his expression serious. "I understand, sir. And while I believe the contract isn't binding, I've decided to compete in the tournament nonetheless."

Dumbledore's eyebrows shot up in surprise. "Indeed? May I ask why?"

Hadrian's lips curved into a slight smirk. "Consider it curiosity, Headmaster. I'm interested in seeing what challenges this tournament has to offer. Besides, it seems like an excellent opportunity to learn more about this... world of yours."

Dumbledore's eyes twinkled with interest at Hadrian's choice of words. "Very well, Mr. Bael. We welcome your participation. Now, perhaps we should continue this discussion in private at a later date, where we can explore all the implications of your unique situation."

"That would be acceptable," Hadrian agreed. "However, I would like to make it clear that while I've chosen to participate, my life and responsibilities lie elsewhere. My presence here is temporary."

The old wizard nodded, a mix of curiosity and concern in his eyes. "Of course, Hadrian. We'll sort out the details. For now, why don't you join us at the feast? We can discuss matters further after everyone has had a chance to eat and calm down."

As the students began to leave the Great Hall, Professor McGonagall stepped forward. "Mr. Bael, if you'll follow me, I'll show you to your quarters."

Hadrian followed the stern-looking witch through the winding corridors of Hogwarts. The castle's ancient magic thrummed around them, and Hadrian couldn't help but feel impressed at the history contained within these walls.

"Here we are," Professor McGonagall said, stopping in front of a large portrait of a medieval wizard. "This will be your room during your stay at Hogwarts. The password is 'Crimson Dawn.' You may change it if you wish."

As the door closed behind Professor McGonagall, Hadrian let out a small sigh. He was grateful for the private room, away from the curious stares of the Hogwarts students. However, his mind was already racing with plans.

"I need to get back," Hadrian murmured to himself. "They'll be worried."

He closed his eyes, focusing on his connection to his Evil Pieces. As a High-Class Devil, he possessed a set of these chess-like pieces, each imbued with demonic power. One of his Rook pieces was currently in the Underworld, in the safety of the Bael family estate.

Hadrian took a deep breath, gathering his demonic energy. It was a risky move, attempting to castle across dimensions, but he knew he had the power to do it. He pictured the Rook piece in his mind, visualizing the swap.

"Castling," he whispered, activating the technique.

A surge of power coursed through him. For a moment, the world seemed to blur and twist. Hadrian felt a sudden pulling sensation, as if he was being yanked through space itself.

When the sensation faded, Hadrian opened his eyes. Instead of the Hogwarts guest room, he found himself standing in the familiar surroundings of his family's mansion in the Underworld. The Rook piece now occupied his place back at Hogwarts.

Hadrian let out a breath of relief. "I'm home," he said softly, a small smile playing on his lips. Now, he could properly inform his family about the situation and plan their next move. The Triwizard Tournament could wait for now; family came first.

I have removed the talk with Sirius. The Goblet of Fire summoning differs from devil summoning. In devil summoning the devil feels a 'call', while in Goblet of Fire summoning they feel a strong 'pull'. Only the house elves noticed Hadrian leave the castle.
