Prologue

The young girl stepped out of the helicopter and looked around nervously. She wasn't sure about this strange man who had called and invited her to his private island. She'd always been jealous of him growing up, but he was practically a stranger to her. The only thing she knew him as was her beloved sister's childhood sweetheart. However, the young Miss Edinburg pushed these negative emotions aside with a slight flip of her fallen hair as she pinned it back up. The girl looked around, surprised that there wasn't anyone there to greet her this time. When the helicopter had picked her up in Los Vegas, there had been two of the man's security agents and a bouquet of a mix of her sister and her flowers, with a note. The note explained that he was not there in person due to a tournament he was hosting which was scheduled to end before she arrived. The note went on to invite her to request any comfort she required during her stay with "her brother". The note had aggravated her. Where did the man get off claiming they were related? She shook her head at her immaturity and refocused on the situation at hand. Something about the difference gave her an ominous feeling deep in her gut. Young Miss Edinburg bit her lip and headed toward the first door she saw. Before going inside the mysterious castle, she took one last look at the island's view.

The girl made her way through the dark maze of the halls. Somehow, she found herself in a brighter, friendlier level of the castle. She sighed in relief when she heard voices. She ran towards the direction of the voices, catching some of the conversation. Something was wrong, though. The male voices sounded worried, and when they came into view, there was something odd about the two men. They were dressed as the other agents had been, with dark suits and sunglasses, and they stood close together. However, they seemed reluctant to have to be speaking.

"Um, excuse me?" she said nervously stepping forward. The two men jumped as if they had been caught committing a crime.

"What are you doing here, punk?" the taller brunette agent demanded aggressively.

"I'm here to see someone named Pegasus? He invited me here last week," she explained quickly.

"You're Miss Edinburg?" the older, grey-haired agent asked in a gravelly voice. The girl nodded apprehensively at the two men looming over her. "Welcome, Miss Edinburg, I apologize for not greeting you when you arrived. Your pilot neglected to confirm his arrival time. My name's Croquet, Head of Security for Maximillion Pegasus. I trust your trip was comfortable?"

"Very much, once I convinced the pilot to fly at a respectable speed," Miss Edinburg replied as the men led her further into the castle.

"Mr. Pegasus has ordered us to ensure your comfort during your stay at Castle Pegasus. We regret to inform you that Mr. Pegasus will not be able to meet with you at the moment. He is currently indisposed from the conclusion of the Duelist Kingdom tournament."

"Oh, that's fine. I don't mind waiting," she said as they came to a halt.

"If you need anything, please don't hesitate to ask," Croquet said bowing before he left with the other agent. The young Edinburg opened the door, eager to see her accommodations. The room was enormous, complete with a king-sized bed, armoire, and vanity. She was pleased to see her luggage trunk was waiting for her. She eagerly changed into more comfortable clothes, having reluctantly dressed up to meet Pegasus. She pulled on the soft, warm purple sweater her sister had sent to her at boarding school. She sat down on the soft, luxurious bed and looked around. Edinburg had always known Pegasus was the sole heir to a large fortune and that he had amassed a large private fortune on top of it from his successful business, Industrial Illusions. The twenty-four year-old tycoon's wealth didn't intimidate or impress her though; in fact, it struck her as ridiculous and over-the-top. It only sealed the girl's determination. Maximillion Pegasus would answer to her for taking the closest thing to a real family she had. The teenager stood up and paced around the room, trying to calm down. When that failed, she decided to follow the path down to the beach.

The young Edinburg girl returned to the castle a few hours later, feeling relaxed and refreshed, totally nonplused about her long hair dripping salt water on the floor. She stopped when she heard anxious whispering around the corner again, amused by the déjà vu.

"This is terrible! First we lose Mr. Pegasus' guest, then we lose Mr. Pegasus," Croquet said, obviously tormented.

The teen stepped forward, "He's gone?"

Croquet and the brunette agent exchanged nervous glances. "Welcome back, Miss Edinburg, I trust your accommodations are to your liking?"

"They're lovely, as expected of Pegasus," she said dismissively. "Now where's Pegasus?"

"Miss Edinburg, Mr. Pegasus has…vanished."

"Vanished? He's…gone?"

"I'm sorry ma'am, you're welcome to stay until Mr. Pegasus returns," Croquet said before walking away. The girl automatically made her way through the castle. She reached her room and closed the door. The click of the door brought her sinking into the carpet, despair and hopelessness swallowing her whole. What am I going to do? she thought desperately. Her only lead about her sister was gone. Slowly, she breathed piecing herself together and made it across the room to sit on the bed. She looked in the large trunk at the foot of the bed for the picture of her and her sister that she always kept. Pegasus had painted it for her years ago to make her sister happy. Young Edinburg smiled sadly as she gazed at the picture. Her fingers moved slightly, brushing the back of the picture, feeling an envelope caught on it. It was a letter from her old friend, whom she called "Uncle" Solomon. In the letter, the old man had been fawning over his grandson, whose name she didn't remember. She frowned and dug through the trunk until she found a picture of the boy Solomon had sent. Yugi, she read and a spark of recognition flashed through her mind. She could have sworn she had heard the name somewhere else. Young Edinburg suddenly remembered what she had overheard when she first arrived.

"I can't believe that Yugi kid from Domino beat Pegasus!" Croquet said.

"That must be why Pegasus is acting so strangely," the other agent whispered.

The girl bit her lip. She knew Solomon and his grandson Yugi lived in a place called Domino City. She wasn't sure if these were the same place. Then, there was the kid. If she remembered correctly, Yugi should be a few years younger than her, about fifteen or sixteen. She also wasn't sure how common "Yugi" was as a name. Could this kid be the link to my sister and Pegasus?
