Chapter I; Wake Up
Sora...
"..."
Sora...wake up...You still have much to do.
"Huh?" Sora groaned. The spikey brown-haired boy's eyes fluttered open and slowly rose up onto his feet. He looked around to find himself in a black, empty void with no sight of any light but could see himself perfectly clear. "Am I... dead?"
"Thankfully, no, you are not dead my friend." spoke a voice from behind him.
Sora turned around to see a man in a black coat with a hood hiding his face. The black coat usually worn by members of Organization XIII. He swiped his hand back and the Kingdom Key materialized in his hand and pointed the keyblade towards the man. "I thought we already dealt with you Organization clowns."
"Woah, woah, settle down there kid. But are you associating me with the 13 Seekers of Darkness? I'm flattered that I look like someone else but that just hurts. I am not a part of those group of troublesome but yet interesting individuals." the man placed his hand on his chest to gesture how offended he was.
"Then who are you? Where are we?" Sora quickly questioned the man.
"So quick to ask questions this time around huh? Well, you can call me the Master of Masters. To answer your second question, you should know exactly where we are. I mean, what do you think we are standing on?"
Sora looked down to see a dimly lit floor of...himself? It appeared to be a large circular platform that looked somewhat familiar to him. He's been here before...when he freed Ventus's heart, before he woke up on the beach before the Destiny Islands were swallowed by darkness, and when he first fought Roxas. Although, the platform was shattered with several pieces missing.
"Is this... my heart?" Sora asked as he placed his hand over his chest where his heart should be.
"I'm afraid so. Although, you don't seem surprised." said the Master of Masters
"Well, I knew that bringing Kairi back would cost me something...I guess it was my life for hers." Sora let out a light chuckle as he threw his arms behind him and placed them on the back of his head. "Wait...I was told that there were three hearts inside of me. There was Ventus, Roxas, and someone else. Is that person you?"
The Master's head turned to look around and then pointed at himself, "Me? Sorry to disappoint you kid but the heart you're speaking of is not mine. That one actually belonged to the girl named Xion. The black-haired girl who battled with you and Roxas when you fought one of the members of that Organization XIII fellows. I'm here inside you because your role has yet to be fulfilled." explained the Master.
"My role?"
"Yes. You see, there is a keyblade out there that has one of my eyes. I put it in this keyblade so that I could be able to see what happens in the future after I disappeared from my own time." the Master glanced at Sora who had a disturbed facial expression. The Master's shoulders lowered and he sighed heavily. "Yes, I placed one of MY eyes inside a keyblade. How disgusting." mocked the Master.
"E-eh I-I'm sorry. That's just... a strange idea. Can I see it?" Sora asked hesitantly.
"I can't."
"Why not?"
A low and rough groan echoed all around them suddenly. The ground shook beneath them. In the dark abyss that surrounded the platform where they stood, a large dark figure rose from its shadowy depths. It was a Darkside. This one looked different however, red markings glowed all throughout its body. Its facial appearance even looked more human than how they usually looked.
"It seems it has found me again. Welp, sorry to cut this conversation short but I'm going to be sending you off now. Do not tell anyone that you have met me." said the Master.
"Wait, what do you mean?" Sora quickly asked.
The Master raised his hand to Sora and he was suddenly covered in light. The platform below started to put itself back together and shined brightly, blinding Sora until all he could see was nothing but the bright white light that consumed him. After a few moments, the light dissipated, leaving only the Master and the new Darkside heartless alone.
"Well now, where were we?... Ah yes." muttered the Master. He turned towards the Darkside and quickly jumped towards it. Before the heartless could make a move, the Master swiped his hand vertically, cutting his opponent in half. "Go now, live on your life...young Sora."
