Prologue Collect the Keys Peace. That is what had been achieved in the part of the universe that Sora's journey had touched. While this part was probably just a tiny part compared to the much more significant whole, it was still peace. With the creation of the World Defense System, or WDS, 50 years ago that peace could finally be taken to other worlds. It would weaken, or even defeat, Heartless, Nobodies, and even Unversed in the worlds without the denizens ever knowing of their existence or being affected by their existence. Thanks to the work of the World Defense Committee, or WDC, the influence of the WDS has been expanded to beyond just the worlds that Sora touched. Thanks to this, more worlds were beginning to become protected from the various threats. It was a slow expansion sure, but the WDC eventually figured that they would be able to speed up the expansion of the WDS' influence. It was what they were striving for. On a day like any other, as most stories begin, Mickey was upon his throne, talking with Queen Minnie. As he did so, the smaller door at the bottom of the gigantic doors that lead into the throne room burst open. A duck was running in with great speed, his feathers ruffled as he was quite flustered. "Your Majesty, there's been an emergency!" the Court Mage Donald Duck called out to the king, his rather obnoxious voice echoing to every part of the throne room. Mickey, obviously quite alarmed and concerned by his good friend's outcry, stood up from his throne and strode to meet Donald somewhat midway in the Throne Room. "What is i--" Before he could even finish though, Donald grabbed his wrist with one of his own feathery appendages. "Its the WDS, you need to see this right away!" With this, Mickey was quickly dragged out of the throne room to the secondary, slightly more accessible, computer room within Disney Castle that was located in the now much larger library. The two of them, Goofy, and Chip and Dale were looking over some recent footage that the WDS had spotted. "The strange signature only appeared for a second, but some of the Heartless are showing signs of not being affected at all!" Spoke one of the chipmunks. Mickey looked at the screen, examining the various bits of data presented to him. "And you're sure its nothing we have ever seen before?" Goofy nodded. "A-hyuk, thats correct your majesty. Of course, it could also be a malfunction to". "That's what I hope it is Goofy... as that would be alot easier to deal with, but with this present on multiple worlds... it is definitely no coincidence". "What should we do?" Donald now turned towards Mickey, ready to carry out any assignment needed. "We need to try and request the help of the new Keybladers the WDS found. In the end, we need to deal with these immune heartless... Donald, go speak with Merlin. He should be able to use his magic to more easily summon and contact them". With Mickey's request, Donald gave a salute and left the room. They needed the help of the Keybladers. While Mickey knew of three, including himself, one of them was out away in a different world and the other was just one person who couldn't be in three worlds at once, the newest recruit to the WDC, Tidus. As for himself, he figured he would tend towards the Defense System more personally through its power source. Of course he was willing to go if needed, but right now he needed to scan the system to see if a hands on scan could help. After about several hours the preparations for calling and summoning the new Keybladers was complete. A special letter would be sent out to each of them. It would either appear in their mailboxes, if they had any, or be delivered to them via other means whether its just being on the ground where they could easily find them or be passed to them through other means. When the Keybladers in these other worlds managed to get the letter and examine it the letter was addressed to them as their name was on the front of the envelope. The letter's contents read as following. The Letter (Move your mouse to reveal the content) The Letter (open) The Letter (close) Dear (The Recipient's name would be here), You may not be aware, but there are other worlds out there. There are as many worlds as there are stars in the sky, the amount being something that no one person could ever count. A long time ago, the worlds were plagued by a threat known as the Heartless, creatures that come from the darkness in peoples hearts. While the major threats of these creatures has been brought down, they still plague worlds to this day. As such, to protect the worlds, a system called the World Defense System, or WDS, was created about fifty years ago. It is a system meant to defeat the Heartless that plagues the worlds and help us monitor them, but its reach was limited. Now though it is expanding its reach to many different worlds, your world being one of them that entered its protection about two years ago. The purpose of this letter is that I need your help. The WDS also has another function. To find wielders of a weapon known as a Keyblade, a special weapon that is the best means of permanently subduing the Heartless, since when defeated through any other means they will just appear elsewhere at a later date. When the system reached your world, it detected that you were indeed a Keyblade wielder. What I need your help for is for investigating a strange anomaly that was spotted on one world. Aside from the Heartless, the WDS is meant to monitor for other threats as well and recently it picked up a strange signature that we have never seen before and unfortunately we lack the manpower to investigate it at the moment, since continuously working to expand the range of the WDS to protect other worlds from the Heartless has taken all we have. As such, I wish to ask for your help in investigating the world that the strange signature was spotted in. If you do not wish to do so, then you are free to say no. We are not forcing you by any stretch of the imagination. Of course, you will not be alone on this manner, as we are asking a few other Keybladers we have recently spotted for help in this matter, since a team is better suited for this situation then just one or two people alone. Again, you do not have to accept our request. If you wish to ignore this request, simply dispose of this letter. If you do accept the request, simply press your thumb upon the seal at the bottom of the letter and say the words 'I accept' and you will be teleported to the place where you will be briefed on your mission. With best regards, King Mickey (The Seal is here) Tidus, in the meantime, would instead receive a different message. Not a letter, since he was already a member of the WDC, but rather on the special bracelet he had been given a transmission would be sent to him. It was from Kazumi, the leader of the WDC, relaying to him that he needed to report to Disney Castle right away due to an urgent matter concerning the WDS arising and his help and Keyblade being needed to investigate the problem.
