Kingdom Hearts: Shadow Saga: Chapter 4: A Shadow's History

In the Mysterious Tower, Master Yen Sid, along with Riku, Lea, Donald and Goofy were in the Master's chamber with a comatose Sora in the background being cared by Kairi. Master Yen Sid then called Riku, Lea and Kairi to his desk where he sat in his chair.

"I called you three here for an important announcement." Master Yen Sid said. "Kairi and Lea are going to be trained by Riku to be Keyblade masters under my teaching's. I've herd word that something bigger is approaching us."

"Are you referring to me Master?" A mysterious voice said with sarcasm.

"It couldn't be…" Master Yen Sid said.

"Oh but it is." The voice said. "Ladies and Gentlemen. I present to you. The one. The only. SHADIX! Can I get an applause?!"

As the voice said this, A corridor of darkness appeared in the chamber and out walked a hooded Shadix.

"Adshi. I thought you were under Ansem's care." Master Yen Sid said.

"First of all, that's not my name." Shadix said. "Secondly, that old coot had no authority over me a long time ago. Twelve years to be exact."

Riku then got closer to Shadix.

"Who do you think you are?" Riku asked. "Either you tells us what you want or I'll 'escort' you out."

As Riku said this, he held his Keyblade, Way To The Dawn, at Shadix's neck.

"Calm down Riku. I only wanted to see my older twin." Shadix said in a faux pleading tone of voice.

"Wait." Riku started. "How did you know my name? And what do you mean by 'older twin'?"

"I know a lot about you and your friends." Shadix said. "I know you and the King closed the door to darkness when Xehenort's Heartless tried to conquer Kingdom Hearts, I also know about Kairi, Lea, AKA Axel, and especially Sora. Who is my older twin brother."

Shadix lowered his hood to show his face, which to Riku's surprise, looked like Sora's. Except Shadix had orange eyes, pale skin and black hair. But his appearance was very similar to Sora's. Kairi then took noticed of it, she then thought if she saw him from behind, she would mistake him for Sora.

"So explain to us." Kairi started. "How come we've haven't seen you until now?"

"I was in hiding most of the time." Shadix started. "It all started when me and Sora were born. One day a man by the name of Ansem the wise. He came for me, because I had darkness, unlike Sora. He took me to Radiant Garden where I spent most of my life in. Sometime during that, a boy by the name of Vanitas came to me one day, he told me that I had potential in using these powers I didn't even know about. He then drew out his Keyblade, and let me hold it. He then said I had a power that will awaken in me someday. Another day, I was in my heart, and this fuming black orb appeared, it said that I was the remains of Vanitas, and needed a place to go. So I let it into my heart. Nine years later, there was an invasion of these things I didn't know what they were at first. Then this witch by the name of Maleficent came to me. She told me that I either had to leave, or be turned into a Heartless. I decided to let her do so. All I remember from that is that I was floating into a black void. Then I regained my thoughts in a new form. I didn't know where I was, or who I was. I was in a dark city, and in the sky was this huge castle. Then A hooded figure came to me, and told me I had a purpose to be with him and his group. Letters forming my former name then appeared. The figure placed an X in the group of letters. They swirled around until they formed a new name: Shadix. The figure then said that this new name was only the beginning. He then took me to the castle. He got the rest of his Organization, which I knew was then called "Organization XIII" and introduced me as Number XV, Shadix, The Shadow Thief. I was put onto a lot of thieving missions during this time. When I herd Sora was coming to the castle, I told Lord Xemnas that I was running for it, which he called me a fool to do. But I did anyway, knowing it was the right thing to do. I then ended up back in Radiant Garden, and that's how my mission began."

Shadix then finished his story. Everyone was listening to him carefully. Not missing a single detail. Lea then finally spoke.

"I remember you now." Lea said. "You used to spy on me, Roxas and Xion back at the clock tower. That was the creepiest thing to do you know."

Shadix then had a confused look on his face.

"How did you know I did so?" Shadix asked.

"I always felt something dripping on my shoulder, when I went to see what it was, I knew from the drippy feel, it was ice cream. I went to taste it, and it was sour, Dark Berry. We all knew you were the only one who could handle Dark Berry Ice Cream. So I knew it was you all along."

Shadix then broke out in an applause.

"Well done Axel." Shadix said sarcastically. "You know how to see for an assassin."

"I'm no longer Axel." Lea pointed out. "I'm Lea. Got it memorized?"

"Very well then." Shadix said. "It seems I can't do anything with Sora at the moment. I'll be on my way then."

Shadix then opened a corridor of darkness.

"But know this." Shadix continued. "I'll be a much bigger foe than both Xemnas AND Marluxia ever were."

Shadix walked into the corridor and I disappeared behind him.

"It seems we got bigger things than we expected." Master Yen Sid said. "Riku, I'm putting you in charge of training Kairi and Lea into becoming Keyblade Masters. We need to act fast. Something greater is happening beyond the shadows."

I know this was long. But I wanted to get this out sooner or later. Well I'll be seeing you in the next Chapter. Thanks for reading. -1up
