Outside the Mysterious Tower, two people are seen training with one person and a moogle onlooking...
Kairi: One more time!
Kairi – A girl who came to the Destiny Islands during a meteor shower. She is one of the seven princesses of hearts and has recently found out that she can wield a keyblade.
Matthew: Okay. Let's go!
Matthew – A boy from the Destiny Islands, Sora's best friend and Nick's younger brother. He inherited his ability to wield a keyblade from Ventus ten years ago and became a keyblade master alongside Riku after restoring the sleeping realm.
After a while...
Matthew: Right. I reckon that's enough for today. You're getting really good, Kairi!
Kairi: Thanks! Well, it's mainly because I had a good teacher.
Matthew: Oh come on. I'm no teacher.
Tina: You're both doing really well.
Tina – A girl from Radiant Garden. Her real name is Terra Branford but when she met the keyblade wielder Terra ten years ago, she named herself Tina she should not dishonour her name. She has the power to turn into an Esper and is really good friends with Matthew.
Mog: Nice job, kupo!
Mog – A moogle who has the power to time travel. He was freed from being encased in a statue by Matthew and has travelled with him ever since.
Matthew: Just doing what I usually do. Now come here, my little moogle buddy!
Mog: No! Don't ruffle my fur, kupo!
Then, Riku exited the tower...
Riku – A boy from the Destiny Islands and Sora and Nick's best friend. At first, he was tempted by the darkness and was controlled by Ansem but has sworn to walk the road to dawn. He became a keyblade master alongside Matthew after restoring the sleeping realm.
Riku: Hey Matthew. Master Yen Sid wants to see us.
Matthew: Okay. Wait here guys.
Riku and Matthew went back into the tower and went to Master Yen Sid...
Yen Sid: Riku. Matthew. You have recently became keyblade masters and I have called you here because there is something amiss in a world far away from here that connects to worlds here and if it is not solved, then the people who have been drawn into that world will never return.
Riku: Never return?
Matthew: How come?
Yen Sid: In that world, there has been a conflict that has lasted ever since the ancient keyblade war but is different. It is a battle between the goddess of harmony, Cosmos, and the god of discord, Chaos. They have summoned warriors to fight for them and a small fraction of them have come from the Radiant Garden.
Matthew: Wait. So then, has Cloud and the other members of the restoration committee been brought into that world?
Yen Sid: That I am unsure of. However, three people have come to three worlds here from that world. One has come here, another has appeared in Twilight Town and the last in Radiant Garden. I want the two of you to find a way to end this conflict so that nobody will brought there again.
Riku: Understood. Nick's already so he should be alright but...
Matthew: I'll go tell Kairi and Tina about what's going on then find out who came here.
Riku: Good. I'll go to Twilight Town then go tell Nick about what's going on.
Matthew: Okay. See you later!
Matthew exited the tower...
Matthew: Listen guys, something's gone wrong in a world and...!
What Matthew saw was that Tina, Kairi and Mog had all been knocked out by a familiar swordsman with a long sword and long, silver hair...
(music playing: One-Winged Angel – Kingdom Hearts II)
Matthew: Sephiroth!
Matthew summoned his keyblades Oathkeeper and Fenrir...
Matthew: I reckon you're the one that Master Yen Sid was talking about! What are you doing here?
Sephiroth: Collecting a comrade. When they tried to interfere, (points his sword toward Kairi and Mog) I defeated them.
Matthew: Collecting a comrade? Tina's no comrade of yours!
Sephiroth: Maybe. But not by choice. Accept it. She is a warrior of Chaos.
Matthew: No. That's not true!
Matthew proceeded to attack Sephiroth but was taken down in one strike...
Sephiroth: Hm. This should be interesting.
Sephiroth brought the knocked out Matthew, Kairi and Tina together and teleported all three of them and himself to the world of the conflict of the gods. Meanwhile, in Radiant Garden...
Nick: 48... 49... 50! Yep. That's all the things Cid needs for the computer.
Nick – A young boy from the Destiny Islands, Riku's best friend and Matthew's older brother. Unlike the others, he doesn't know how he's able to wield a keyblade. His keyblade was originally Oblivion and it had the unique ability to absorb Heartless but during the battle of 1000 Heartless, it was destroyed and was reincarnated into Darkest Oblivion. Nick is also aware of the vast darkness in his heart and is unsure why he has so much of it.
Nick: Right. I'd best get this over to Merlin's house. But how am I going to carry all of it? Maybe if I cast Zero Gravity, it'll be able to-
Yuffie: Nick!
Nick saw Yuffie running over to him...
Nick: Oh hey Yuffie. What's up?
Yuffie: Leon, Zidane, Cloud, Tifa and Lightning just disappeared!
Nick: What?!
Yuffie: I don't know what happened. They were there one minute and then gone the next!
Nick: Okay. I'll go look around to find out what's going on.
Nick proceeded to look around the two to find what happened to them. But when he got to the Bailey...
?: Hmm... It seems the prelude has begun.
Nick: Who's there? Show yourself!
A kind-looking man with long silver hair appeared...
Nick: Who are you? Haven't seen you in around Radiant Garden before. Have you got something to do with Leon and the others' disappearance?
?: Don't worry. All of your questions will be answered soon enough. Are you the keyblade wielder Nick?
Nick: Yeah. So?
Kuja: My name is Kuja. I am an acquaintance of Zidane and I'm afraid that me, him and the others you refer to are in the midst of a grand conflict of the gods.
Nick: A conflict of the gods? What do you mean?
Kuja: It is a battle between the god of discord, Chaos, and the goddess of harmony, Cosmos. Zidane and I fight for Cosmos and we, along with an assortment of allies, must defeat Chaos and his warriors if we ever wish for an end to this conflict. However...
Nick: You need help?
Kuja: That is why I'm here. I need you to come and help us this conflict. I had hoped that the conflict will end but if you helped, I feel that it will be a certainty.
Nick: My friends are in this conflict and I'm gonna help them. Count me in, Kuja!
Kuja: Marvellous.
Kuja summoned a portal that led to the world where the conflict is taking place...
Kuja: Come. Let us see this new actor take to the stage and turn this never ending drama into a victory cry.
Kuja went into the portal shortly followed by Nick. Meanwhile, at Twilight Town, Riku had made his way to the clock tower...
Riku: It's been a while since I've been here.
Riku gazed out to the sunset and felt a brief moment of nostalgia. However, that nostalgia came to halt as he felt the presence of someone who could use the darkness. He turned around quickly and saw an armoured man with a cape...
Riku: Who are you?
?: I am a warrior of Chaos. As you may already know, a conflict of the gods is forcing more of your friends into it. Your fellow wielders of the keyblade are being brought into it as well.
Riku: What?! You mean Matthew, Nick and Kairi?! Sora and Mickey too?!
?: I am unsure which of them have joined the conflict but I advise you should do the same if you want to see them again!
The man raised his hands and teleported him and Riku to the other world. Now that these four new heroes have been brought into the conflict, can they rewrite what destiny has in store for them and their friends? To be continued...
